Lower Limb Prostheses - Policy Article

NON-MEDICAL NECESSITY COVERAGE AND PAYMENT RULES

For any item to be covered by Medicare, it must 1) be eligible for a defined Medicare benefit category, 2) be reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member, and 3) meet all other applicable Medicare statutory and regulatory requirements. Information provided in this policy article relates to determinations other than those based on Social Security Act §1862(a)(1)(A) provisions (i.e. “reasonable and necessary”).

Lower limb prostheses are covered under the Medicare Artificial Legs, Arms and Eyes benefit (Social Security Act §1861(s)(9)). In order for a beneficiary's lower limb prosthesis to be eligible for reimbursement, the reasonable and necessary (R&N) requirements set out in the related Local Coverage Determination must be met. In addition to meeting the benefit policy, there are specific statutory payment policy requirements, discussed below, that also must be met.

GENERAL:

A repair is a restoration of the prosthesis to correct problems due to wear or damage.

An adjustment is any modification to the prosthesis due to a change in the beneficiary's condition or to improve the function of the prosthesis.

The following items are included in the reimbursement for a prosthesis and, therefore, are not separately billable to Medicare under the prosthetic benefit:

• Evaluation of the residual limb and gait

• Fitting of the prosthesis

• Cost of base component parts and labor contained in HCPCS base codes

• Repairs due to normal wear or tear within 90 days of delivery

• Adjustments of the prosthesis or the prosthetic component made when fitting the prosthesis or component and for 90 days from the date of delivery when the adjustments are not necessitated by changes in the residual limb or the beneficiary's functional abilities.

Payment for Prostheses Provided During a Medicare Part A Covered Hospital Stay

Payment by Medicare Part A for a prosthesis provided to a beneficiary for use during a Medicare Part A covered hospital stay is eligible for inclusion in the payment for the hospital stay if the following criteria (1 and 2) are met:

1. The prosthesis is provided to a beneficiary during the inpatient hospital stay; and,

2. The beneficiary uses the prosthesis for reasonable and necessary inpatient treatment or rehabilitation.

In this situation, a claim must not be submitted to the DME MAC.

Payment by the DME MAC for a prosthesis delivered to a beneficiary, not for use during a Medicare Part A covered hospital stay, is eligible for DME MAC coverage if the following criteria (1 – 3) are met:

1. The prosthesis is reasonable and necessary for a beneficiary after discharge from a hospital; and,

2. The prosthesis is delivered to the beneficiary no more than two days prior to discharge to home; and,

3. The prosthesis is not used for inpatient treatment or rehabilitation.

Payment for Prostheses Provided During a Medicare Part A Covered Skilled Nursing Facility (SNF) Stay

Payment by Medicare Part A for a prosthesis provided to a beneficiary, described by codes L5000, L5010, L5020, L5400, L5410, L5420, L5430, L5450, L5460, L5987, L8400, L8410, L8417, L8420, L8430, L8440, L8460, L8470, and L8480, for use during a Medicare Part A covered SNF stay is eligible for inclusion in the payment for the SNF stay if the following criteria (1 and 2) are met:

1. The prosthesis is provided to a beneficiary during the SNF stay; and,

2. The beneficiary uses the prosthesis for reasonable and necessary treatment or rehabilitation.

In this situation, a claim must not be submitted to the DME MAC.

Claims (other than for the above HCPCS codes) for a lower limb prosthesis provided to a beneficiary during a Medicare Part A covered SNF stay (see below), and claims for any lower limb prosthesis provided to a beneficiary during a non-covered Medicare Part A SNF stay, are to be submitted to the DME MAC.

Payment by the DME MAC for a prosthesis delivered to a beneficiary during a Part A covered SNF stay is eligible for DME MAC coverage if:

1. The prosthesis is reasonable and necessary for a beneficiary’s use during the Medicare Part A covered SNF stay; and,

2. The prosthetic components are classified as major category III codes under the SNFs consolidated billing.

ADJUSTMENTS, REPAIRS, AND COMPONENT REPLACEMENT:

Routine periodic servicing, such as testing, cleaning, and checking of the prosthesis is noncovered. Adjustments to a prosthesis required by wear or by a change in the beneficiary's condition are covered under the initial treating practitioner's order for the prosthesis for the life of the prosthesis.

Repairs to a prosthesis are covered when necessary to make the prosthesis functional. If the expense for repairs exceeds the estimated expense of purchasing another entire prosthesis, no payments can be made for the amount of the excess. Maintenance which may be necessitated by manufacturer's recommendations or the construction of the prosthesis and must be performed by the prosthetist is covered as a repair.

Replacement of a prosthesis or prosthetic component is covered if the treating practitioner orders a replacement device or part because of any of the following:

1. A change in the physiological condition of the beneficiary; or

2. Irreparable wear of the device or a part of the device; or

3. The condition of the device, or part of the device, requires repairs and the cost of such repairs would be more than 60% of the cost of a replacement device, or of the part being replaced.

Replacement of a prosthesis or prosthetic components required because of loss or irreparable damage may be reimbursed without a practitioner's order when it is determined that the prosthesis as originally ordered still fills the beneficiary's medical needs.

MISCELLANEOUS:

A prosthetic donning sleeve (L7600) will be denied as noncovered.

REQUIREMENTS FOR SPECIFIC DMEPOS ITEMS PURSUANT TO Final Rule 1713 (84 Fed. Reg Vol 217)

Final Rule 1713 (84 Fed. Reg Vol 217) requires a face-to-face encounter and a Written Order Prior to Delivery (WOPD) for specified HCPCS codes. CMS and the DME MACs provide a list of the specified codes, which is periodically updated. The required Face-to-Face Encounter and Written Order Prior to Delivery List is available here.

Claims for the specified items subject to Final Rule 1713 (84 Fed. Reg Vol 217) that do not meet the face-to-face encounter and WOPD requirements specified in the LCD-related Standard Documentation Requirements Article (A55426) will be denied as not reasonable and necessary.

If a supplier delivers an item prior to receipt of a WOPD, it will be denied as not reasonable and necessary. If the WOPD is not obtained prior to delivery, payment will not be made for that item even if a WOPD is subsequently obtained by the supplier. If a similar item is subsequently provided by an unrelated supplier who has obtained a WOPD, it will be eligible for coverage.

POLICY SPECIFIC DOCUMENTATION REQUIREMENTS

In addition to policy specific documentation requirements, there are general documentation requirements that are applicable to all DMEPOS policies. These general requirements are located in the DOCUMENTATION REQUIREMENTS section of the LCD.

Refer to the LCD-related Standard Documentation Requirements article, located at the bottom of this Policy Article under the Related Local Coverage Documents section for additional information regarding GENERAL DOCUMENTATION REQUIREMENTS and the POLICY SPECIFIC DOCUMENTATION REQUIREMENTS discussed below.

When submitting a prosthetic claim, the billed code for knee, foot, ankle and hip (HCPCS codes L5610, L5611, L5613, L5614, L5616, L5710, L5711, L5712, L5714, L5716, L5718, L5722, L5724, L5726, L5728, L5780, L5810, L5811, L5812, L5814, L5816, L5818, L5822, L5824, L5826, L5828, L5830, L5840, L5848, L5856, L5857, L5858, L5859, L5930, L5961, L5970, L5971, L5972, L5973, L5974, L5975, L5976, L5978, L5979, L5980, L5981, L5982, L5984, L5985, L5986, L5987) components must be submitted with modifiers K0 - K4, indicating the expected beneficiary functional level. This expectation of functional ability information must be clearly documented and retained in the prosthetist's records. The simple entry of a K modifier in those records is not sufficient. There must be information about the beneficiary’s history and current condition which supports the designation of the functional level by the prosthetist.

For L5859, the medical records should describe the nature and extent of the comorbidity of the spine or the sound limb which is what is limiting this beneficiary to a household ambulator, and clearly document how this feature will enable the beneficiary to function as a community ambulator.

Refer to the Supplier Manual for more information on documentation requirements.

REPAIR/REPLACEMENT (BPM Ch 15, §120)

Adjustments and repairs of prostheses and prosthetic components are covered under the original order for the prosthetic device.

Medicare payment may be made for the replacement of prosthetic devices which are artificial limbs, or for the replacement of any part of such devices, without regard to continuous use or useful lifetime restrictions if a treating practitioner determines that the replacement device, or replacement part of such a device, is reasonable and necessary. Claims involving the replacement of a prosthesis or major component (foot, ankle, knee, socket) must be supported by a new treating practitioner's order and documentation supporting the reason for the replacement. The reason for replacement must be documented by the treating practitioner, either on the order or in the medical record, and must fall under one of the following:

1. A change in the physiological condition of the patient resulting in the need for a replacement. Examples include but are not limited to, changes in beneficiary weight, changes in the residual limb, beneficiary functional need changes; or,

2. An irreparable change in the condition of the device, or in a part of the device resulting in the need for a replacement; or,

3. The condition of the device, or the part of the device, requires repairs and the cost of such repairs would be more than 60 percent of the cost of a replacement device, or, as the case may be, of the part being replaced.

The prosthetist must retain documentation of the prosthesis or prosthetic component replaced, the reason for replacement, and a description of the labor involved irrespective of the time since the prosthesis was provided to the beneficiary. This information must be available upon request. It is recognized that there are situations where the reason for replacement includes but is not limited to: changes in the residual limb; functional need changes; or irreparable damage or wear/tear due to excessive beneficiary weight or prosthetic demands of very active amputees.

CONTINUED MEDICAL NEED

For all DMEPOS items, the initial justification for medical need is established at the time the item(s) is first ordered, therefore, beneficiary medical records demonstrating that the item is reasonable and necessary are created just prior to, or at the time of, the creation of the initial prescription. Once initial medical need is established, unless continued coverage requirements are specified in the LCD, ongoing need for the lower limb prosthesis is assumed to be met. There is no requirement for further documentation of continued medical need as long as the beneficiary continues to meet the Artificial Legs, Arms and Eyes benefit.

MODIFIERS

LT and RT MODIFIERS:

The right (RT) and left (LT) modifiers must be used with prosthesis codes (refer to the CODING GUIDELINES section for additional information).

CODING GUIDELINES

REPAIR AND LABOR CODING

Code L7510 is used to bill for any "minor" materials (i.e., those without specific HCPCS codes) used to achieve the adjustment and/or repair.

Code L7520 is used to bill for labor associated with adjustments and repairs that either do not involve replacement parts or that involve replacement parts billed with code L7510. Code L7520 must not be billed for labor time involved in the replacement of parts that are billed with a specific HCPCS code. Labor is included in the allowance for those codes.

One unit of service of code L7520 represents 15 minutes of labor time. Documentation must exist in the supplier's records indicating the specific adjustment and/or repair performed and the time involved. The time reported for L7520 must only be for actual repair time. Time performing the following services (not all-inclusive) must not be billed using code L7520:

• Evaluation to determine the need for a repair or adjustment or follow-up assessment

• Evaluation of problems regarding the fit or function of the prosthesis

• General beneficiary education or gait instruction

• Programming of electronic componentry

SUSPENSION

Code L5671 includes both the part of the suspension locking mechanism that is integrated into the prosthesis socket and the pin(s), lanyard, or other component which is attached to the socket insert. L5671 does not include the socket insert itself. The socket inserts used in conjunction with a suspension locking mechanism are billed with codes L5673, L5679, L5681, or L5683, as appropriate. These codes include socket inserts with or without a distal umbrella adapter for attaching the pin or lanyard of the locking mechanism.

Codes L5681 and L5683 are for use only with the initial issue of a custom fabricated socket insert. Additional inserts (either custom fabricated or prefabricated) provided at the time of initial issue or replacement socket inserts are coded L5673 and L5679, whichever is applicable.

Codes L5647 and L5652 describe a modification to a prosthetic socket that incorporates a suction valve in the design. The items described by these codes are not components of a suspension locking mechanism (L5671).

L5781 describes a complete device that is an addition to a lower limb prosthesis. The primary function of the vacuum pump is to suspend the prosthetic limb. Additionally, products coded L5781 provide residual limb volume management and moisture evacuation. The pump mechanism evacuates air and accumulated moisture between the limb and socket walls. The pump mechanism can be actuated by either external power and/or mechanical system(s).

L5782 describes a complete device that is an addition to a lower limb prosthesis. The primary function of the vacuum pump is to suspend the prosthetic limb. It also provides residual limb volume management and moisture evacuation. The pump mechanism evacuates air and accumulated moisture between the limb and socket walls. The pump mechanism can be actuated by either external power and/or mechanical system(s). Products described by this code would have components built to withstand higher prosthetic limb forces than L5781.

Code L7700 (GASKET OR SEAL, FOR USE WITH PROSTHETIC SOCKET INSERT, ANY TYPE, EACH) describes a stand-alone (i.e., not integrated into or a part of a prosthetic socket insert) sealing ring that is added to a socket insert to assist in providing or maintaining negative pressure for socket suspension. The ring creates a seal against the outer surface of the insert and against the inner wall of the socket. L7700 is not intended for use with mechanical socket suspensions such as a pin-lock system. It may be made of any suitable material. L7700 may be used with upper or lower extremity sockets. Unit of service (UOS) is 1 (one) item. This code is not to be used to bill for gaskets, seals, or other sealing materials that are included as part of an insert. Integrated seals are included in the code for the insert. Separate billing of integrated gaskets or seals as L7700 is unbundling.

PROSTHETIC SYSTEMS

Exoskeletal prosthetic lower limb codes L5200, L5250, L5270, L5280 include a molded prosthetic socket, and exoskeletal single axis knee-shin system, and a SACH foot.

L5150 and L5160 includes a knee disarticulation molded prosthetic socket, external knee joints, and a SACH foot.

Endoskeletal prosthetic lower limb codes L5312, L5321, L5331, L5341 include molded prosthetic socket, an endoskeletal single axis knee-shin system and a SACH foot.

L5100, L5105, L5301 includes a below knee molded prosthetic socket, and a SACH foot.

SOCKETS

Codes L5940, L5950, and L5960 for ultra-light materials may only be used when materials such as carbon fiber, fiberglass, Kevlar, or other advanced composite lamination materials are used in the fabrication of a socket for an endoskeletal prosthesis. They are not used for ultralight materials used in other components of a prosthesis – e.g., knee/shin system, pylon, ankle, foot. For codes L5940, L5950, and L5960, the unit of service is per limb.

L5301, L5540, L5321, L5590 should not be used when billing a replacement socket for an existing prosthesis. The use of L5301, L5540, L5321, L5590 with a replacement socket is incorrect coding (unbundling). Code L5999 (LOWER EXTREMITY PROSTHESIS, NOT OTHERWISE SPECIFIED) must not be used to bill for any features or functions included in the socket or addition codes. Use of L5999 is incorrect coding (unbundling).

Infinite Socket (LIM Innovations) is an open-socket design that has distinct below knee and above knee products. These sockets are custom-fabricated from a model of the patient's residual limb and utilize struts that extend from a base to an adjustable brim enclosing an inner shell to form the primary structure of the socket. The LIM Innovations socket is functionally equivalent to design features of current HCPCS codes. The correct combination of HCPCS codes for the Infinite Socket TT-S (below-knee socket) are L5301 or L5700 with the addition of L5629, L5637, and L5940. The correct combination of HCPCS codes for the Infinite Socket T/F (above-knee socket) are L5321 or L5701 with the addition of L5631, L5649, and L5950.

PROTECTIVE COVERS

Lower limb prosthetic covers (L5704, L5705, L5706, and L5707) are complete products and afford shape, protection and waterproofing for normal daily usage of the prosthesis. They offer sufficient protection and weatherproofing for beneficiaries who require lower limb prosthetics.

Protective outer surface covering systems (L5962, L5964, and L5966) are specialized covers intended to be worn over an existing prosthesis. They are used by a beneficiary who has special needs for protection against unusually harsh environmental situations where it is necessary to protect the lower limb prosthesis beyond the level of protection that is afforded by L5704, L5705, L5706, and L5707. They are not for cosmetic or convenience reasons, or for everyday usage in a typical environment. Protective outer surface coverings are different from the covering that is already reimbursed as part of L5704, L5705, L5706, and L5707.

FOOT COVERS

Foot covers are included in the codes for a prosthetic foot component and are not separately payable.

KNEES

With the exception of items described by specific HCPCS codes, there should be no separate billing and there is no separate payment for a component or feature of a microprocessor controlled knee, including but not limited to real time gait analysis, continuous gait assessment, or electronically controlled static stance regulator.

Addition codes for exoskeletal knee-shin systems are L5710, L5711, L5712, L5714, L5716, L5718, L5722, L5724, L5726, L5728, L5780 are considered an upgrade to the knee-shin system. The beneficiary may qualify for an upgraded knee-shin system depending on their assigned K-level modifier (K0-K4), as referenced in the LCD. These HCPCS codes can fully describe a complete prosthetic knee-shin system commonly referred to as a “base knee code”. A single addition code can fully describe a complete knee-shin system and thus the use of two codes from the list would be considered incorrect coding (unbundling).

Addition codes for endoskeletal knee-shin systems are L5610, L5611, L5613, L5616, L5810, L5811, L5812, L5814, L5816, L5818, L5822, L5824, L5826, L5828, L5830, L5840 are considered an upgrade to the knee-shin system. The beneficiary may qualify for an upgraded knee-shin system based on their assigned K-Level modifier (K0-K4), as referenced in the LCD. These HCPCS codes can fully describe a complete prosthetic knee-shin system commonly referred to as a “base knee code”. A single addition code can fully describe a complete knee-shin system and thus the use of two codes (L5610, L5611, L5613, L5616, L5810, L5811, L5812, L5814, L5816, L5818, L5822, L5824, L5826, L5828, L5830, L5840) would be considered incorrect coding (unbundling).

L5925, L5930, L5845, L5848, L5850, L5856, L5857, L5858, L5859 are additional features and/or functions that do not describe a complete endoskeletal knee-shin system and must be used in combination with an L-code for a knee-shin system (L5610, L5611, L5613, L5616, L5810, L5811, L5812, L5814, L5816, L5818, L5822, L5824, L5826, L5828, L5830, L5840). The use of additional feature L-codes may also depend on the assigned K-Level modifier (K0-K4), as referenced in the LCD.

L5856 refers to a feature of an endoskeletal knee component which is incorporated into the entire knee-shin system. The microprocessor componentry with sensors, any type, provide automated adjustment for controlling the swing and stance phase of gait. This feature would be discernable from schematic drawings and user manual documentation. The documentation would provide details for all of the adjustments for the dynamic properties of this sub-system within the knee component. Adjustments could factor user characteristics such as the activity level, body weight, or gait preferences, among others. This adjustment feature is energized by an on-board rechargeable battery source. The code would include any external components needed to access the microprocessor for modification of the settings.

L5857 refers to a feature of an endoskeletal knee component which is incorporated into the entire knee-shin system. The microprocessor componentry with sensors, any type, provide automated adjustment for controlling the swing phase of gait. The documentation would provide details for all of the adjustments for the dynamic properties of this sub-system within the knee component. Adjustments could factor user characteristics such as the activity level, body weight, or gait preferences, among others. This adjustment feature is energized by an on-board rechargeable battery source. The code would include any external components needed to access the microprocessor for modification of the settings.

L5858 refers to a feature of an endoskeletal knee component which is incorporated into the entire knee-shin system. The microprocessor componentry with sensors, any type, provide automated adjustment for controlling the stance phase of gait. The documentation would provide details for all of the adjustments for the dynamic properties of this sub-system within the knee component. Adjustments could factor user characteristics such as the activity level, body weight, or gait preferences, among others. This adjustment feature is energized by an on-board rechargeable battery source. The code would include any external components needed to access the microprocessor for modification of the settings.

ANKLE AND LOWER EXTREMITY MOTION UNITS

Codes L5968, L5982, L5984, L5985, L5986 and L5988 describe separate products which provide either a single motion or a combination of motions generally attributed to functional movement of the lower limb during ambulation. The use of these codes can be used to fully describe additional features or functions not found in the prosthetic foot system (L5969, L5970, L5971, L5972, L5973, L5974, L5975, L5976, L5978, L5979 L5980, L5981 and L5987).

L5968 describes a product that is used as an addition to L-code foot systems for lower limb prosthesis construction. The product provides multiaxial motion in the coronal and sagittal plane from articulating components. At transition of stance phase to swing phase, the product will increase the ankle’s dorsiflexion angle and maintain it throughout swing phase. The product provides an accommodation of changing heel heights without the user’s input. The predicate product is the Rincoe R-Hab Ankle manufactured by R.G. Rincoe & Associates, Inc.

L5982 describes an exoskeletal device that allows adjustable amount of vertical twisting motion between the foot and pelvis during ambulation.

L5984 describes an endoskeletal device that allows an adjustable, or non-adjustable, amount of vertical twisting motion between the foot and pelvis during ambulation.

L5985 describes an endoskeletal pylon device that provides simulated multiaxial ankle motion through a dynamic vertical shank separate from any similar incidental prosthetic foot motions. The predicate product is The Seattle Ankle manufactured by Seattle Medical Systems Group.

L5986 describes a product that is used as an addition to L-code foot systems for lower limb prosthesis construction. The product provides multiaxial motion in all three planes of motion, sagittal, coronal, and transverse. This code does not describe the multiaxial motion achieved from the inherent flexibility of the prosthetic keel or a split keel/heel prosthetic foot design. The predicate product is a device that was manufactured by Medical Center Prosthetic, which is represented in the coding narrative by “MCP.”

Use of L5968, L5982, L5984 or L5986 is based on the beneficiary’s K-level modifier (K0-K4), as referenced in the LCD.

L5988 describes an endoskeletal pylon device that allows vertical shock reduction between the foot and pelvis during ambulation. The vertical shock reducing pylon feature of L5988 is a separate function from other products which use a piston/telescoping mechanism such as products described by L5781 or L5782. The predicate product is the Total Shock that was manufactured by Century XXII International, Inc.

FEET

Addition codes for lower extremity prostheses, L5970, L5971, L5972, L5974, L5975, L5976, L5978, L5979, L5980, L5981, L5987 are considered an upgrade to the SACH foot. The beneficiary may qualify for an upgraded prosthetic foot based on their assigned K-level modifier (K0-K4) as referenced in the LCD. A single addition code (L5970, L5971, L5972, L5974, L5975, L5976, L5978, L5979, L5980, L5981, L5987) can fully describe a complete foot and thus the use of more than one code would be considered incorrect coding (unbundling).

L5968, L5982, L5984, L5985, L5986, L5988, L5990 are additional features and/or functions that do not describe a complete prosthetic foot and may be used in combination with L5970, L5971, L5972, L5974, L5975, L5976, L5978, L5979, L5980, L5981, and L5987. The use of additional feature L-codes may also depend on the assigned K-Level modifier (K0-K4) as referenced in the LCD.

L5980 describes a product that can be used for either endoskeletal or exoskeletal lower limb construction. The Flex Foot has an energy storing J-shaped keel design. Heel component is attached onto the J-shaped keel section. The Flex Foot System’s J-shaped keel design extends proximally as a monolithic composite shank. Shank height is determined and modified by supplier to utilize the dynamics of the composite shank. L5980 includes foot cover.

L5981 describes a product that can be used for either endoskeletal or exoskeletal lower limb construction. The Flex Walk has an energy storing J-shaped keel design. Heel component is attached to the J-shaped keel section. The Flex Walk J-shaped keel design proximally terminates at a nonadjustable fixed height determined and modified by the prosthetic foot manufacturer. L5981 includes foot cover.

L5987 describes a product that can be used for either endoskeletal or exoskeletal lower limb construction. All components are integrated as a single product, i.e. not an assembly of separate products or components. The product has an energy storing J-shaped keel design. Heel component is attached onto the J-shaped keel section. Vertical loading pylon allows controlled motion for shock absorption. This code does not describe vertical loading or shock absorption achieved from the inherent flexibility of the J-shaped keel section. L5987 includes foot cover.

PARTIAL FOOT AND TOE FILLER INSERTS

Codes L5000, L5010, and L5020 describe products that are necessary for standing balance and toe off support in beneficiaries who are missing the forefoot or digits including the hallux (great toe) and who require the rigidity and support offered by these products, in order to achieve or maintain an effective gait.

L5000 describes a shoe insert with a rigid longitudinal arch support that also incorporates material accommodating the void left by the missing digit(s) or forefoot. Additional soft material is added where contact is made with the residual limb or toes. These inserts are designed to provide standing balance and toe off support for improved gait. L5000 is inclusive of variations in materials or combinations such as differing stiffnesses or Shore value.

L5010 describes a partial foot device including a molded socket for the residual limb with a proximal height terminating at the ankle or extending proximally as needed to achieve appropriate support and function. L5010 is inclusive of a rigid longitudinal arch support that also incorporates material accommodating the void left by the missing digit(s) or forefoot. Additional soft material is added where contact is made with the residual limb or toes. L5010 devices are designed to provide standing balance and toe off support for improved gait. All closures are included, any type. L5010 is inclusive of variations in materials or combinations such as differing stiffnesses or Shore value.

L5020 describes a partial foot device including a molded socket for the residual limb with a proximal height terminating at or near the tibial tubercle to achieve appropriate support and function. L5020 is inclusive of a rigid longitudinal arch support that also incorporates material accommodating the void left by the missing digit(s) or forefoot. Additional soft material is added where contact is made with the residual limb or toes. L5020 devices are designed to provide standing balance and toe off support for improved gait. All closures are included, any type. L5020 is inclusive of variations in materials or combinations such as differing stiffnesses or Shore value.

MICROPROCESSOR ANKLE FOOT SYSTEMS

With the exception of items described by specific HCPCS codes, there should be no separate billing and there is no separate payment for a component or feature of a microprocessor controlled foot, including but not limited to real time gait analysis, continuous gait assessment, or electronically controlled static stance regulator.

L5973 describes an endoskeletal device with integrated energy storage and release foot and microprocessor ankle system. The integrated microprocessor is programmable along with sensors to optimize plantar and dorsiflexion angles for stance and swing phase. L5973 includes foot cover, power source(s) and charger.

A microprocessor ankle-foot system with power assist (BiOM Ankle-Foot System by iWalk, Inc) is coded as the combination of L5969 (ADDITION, ENDOSKELETAL ANKLE-FOOT OR ANKLE SYSTEM, POWER ASSIST, INCLUDES ANY TYPE MOTOR(S)) and L5973 (ENDOSKELETAL ANKLE FOOT SYSTEM, MICROPROCESSOR CONTROLLED FEATURE, DORSIFLEXION AND/OR PLANTAR FLEXION CONTROL, INCLUDES POWER SOURCE).

The right (RT) and left (LT) modifiers must be used with prosthesis codes. Effective for claims with dates of service (DOS) on or after 3/1/2019, when the same code for prostheses, sockets, or components for bilateral amputees are billed on the same date of service bill each item on two separate claim lines using the RT and LT modifiers and 1 unit of service (UOS) on each claim line. Do not use the RTLT modifier on the same claim line and billed with 2 UOS. Claim lines billed without the RT and/or LT modifiers, or with RTLT on the same claim line and 2 UOS, will be rejected as incorrect coding.

Coding Batteries and Chargers Concurrently With a Powered Base Item

Powered base items are those that contain the power source (battery). At the time that a base item is billed, all necessary batteries and/or battery chargers are considered as included in the payment for the powered base item. There is no separate payment for batteries (L7360, L7364, and L7367) and/or battery chargers (L7362, L7366, and L7368) billed concurrently with a powered base item.

Payments for items listed in Column II are included in the payment for each Column I code. Claims for Column II items billed with the provision of a Column I item will be denied as unbundling.

Suppliers should contact the DME PDAC contractor for guidance on the correct coding of these items.

CODING VERIFICATION REVIEW

The only products which may be billed using the following list of HCPCS codes are those for which a written coding verification review (CVR) has been made by the Pricing, Data Analysis, and Coding (PDAC) contractor and subsequently published on the Product Classification List (PCL). Information concerning the documentation that must be submitted to the PDAC for a CVR can be found on the PDAC web site or by contacting the PDAC. A PCL with products which have received a coding verification can be found on the PDAC web site. The effective date of the CVR is included for each code.

Effective for claims with dates of service on or after January 1, 2014:
L5969

Effective for claims with dates of service on or after January 1, 2021:
L5856, L5857, L5858, L5973, L5980, L5987

If a product is billed to Medicare using a HCPCS code that requires written CVR, but the product is not on the PCL for that particular HCPCS code, then the claim line will be denied as incorrect coding.
