Power Mobility Devices

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.

The purpose of a Local Coverage Determination (LCD) is to provide information regarding “reasonable and necessary” criteria based on Social Security Act § 1862(a)(1)(A) provisions.

In addition to the “reasonable and necessary” criteria contained in this LCD there are other payment rules, which are discussed in the following documents, that must also be met prior to Medicare reimbursement:

• The LCD-related Standard Documentation Requirements Article, located at the bottom of this policy under the Related Local Coverage Documents section.
• The LCD-related Policy Article, located at the bottom of this policy under the Related Local Coverage Documents section.
• Refer to the Supplier Manual for additional information on documentation requirements.
• Refer to the DME MAC web sites for additional bulletin articles and other publications related to this LCD.

For the items addressed in this LCD, the “reasonable and necessary” criteria, based on Social Security Act § 1862(a)(1)(A) provisions, are defined by the following coverage indications, limitations and/or medical necessity.

The term “treating practitioner” is defined as both physicians (defined in section 1861(r)(1) of the Social Security Act) and non-physician practitioners (i.e., PA, NP, and CNS; defined in section 1861(aa)(5) of the Social Security Act).

The term power mobility device (PMD) includes power operated vehicles (POVs) and power wheelchairs (PWCs).

Power Mobility Device bases require a Standard Written Order (SWO) prior to delivery. The SWO may also list all associated options and accessories that are billed separately. Refer to this LCD’s related Policy Article for more information.


 GENERAL COVERAGE CRITERIA:

All of the following basic criteria (A-C) must be met for a power mobility device (K0800, K0801, K0802, K0806, K0807, K0808, K0812, K0813, K0814, K0815, K0816, K0820, K0821, K0822, K0823, K0824, K0825, K0826, K0827, K0828, K0829, K0835, K0836, K0837, K0838, K0839, K0840, K0841, K0842, K0843, K0848, K0849, K0850, K0851, K0852, K0853, K0854, K0855, K0856, K0857, K0858, K0859, K0860, K0861, K0862, K0863, K0864, K0868, K0869, K0870, K0871, K0877, K0878, K0879, K0880, K0884, K0885, K0886, K0890, K0891, K0898) or a push-rim activated power assist device (E0986) to be covered. Additional coverage criteria for specific devices are listed below.

1. The beneficiary has a mobility limitation that significantly impairs his/her ability to participate in one or more mobility-related activities of daily living (MRADLs) such as toileting, feeding, dressing, grooming, and bathing in customary locations in the home. A mobility limitation is one that:
   • Prevents the beneficiary from accomplishing an MRADL entirely, or
   • Places the beneficiary at reasonably determined heightened risk of morbidity or mortality secondary to the attempts to perform an MRADL; or
   • Prevents the beneficiary from completing an MRADL within a reasonable time frame.
2. The beneficiary’s mobility limitation cannot be sufficiently and safely resolved by the use of an appropriately fitted cane or walker.
   
   
3. The beneficiary does not have sufficient upper extremity function to self-propel an optimally-configured manual wheelchair in the home to perform MRADLs during a typical day.
   • Limitations of strength, endurance, range of motion, or coordination, presence of pain, or deformity or absence of one or both upper extremities are relevant to the assessment of upper extremity function.
   • An optimally-configured manual wheelchair is one with an appropriate wheelbase, device weight, seating options, and other appropriate nonpowered accessories.

POWER OPERATED VEHICLES (K0800, K0801, K0802, K0806, K0807, K0808, K0812):

A POV is covered if all of the basic coverage criteria (A-C) have been met and if criteria D-I are also met.

4. The beneficiary is able to:
   • Safely transfer to and from a POV, and
   • Operate the tiller steering system, and
   • Maintain postural stability and position while operating the POV in the home.
5. The beneficiary’s mental capabilities (e.g., cognition, judgment) and physical capabilities (e.g., vision) are sufficient for safe mobility using a POV in the home.
   
   
6. The beneficiary’s home provides adequate access between rooms, maneuvering space, and surfaces for the operation of the POV that is provided.
   
   
7. The beneficiary’s weight is less than or equal to the weight capacity of the POV that is provided and greater than or equal to 95% of the weight capacity of the next lower weight class POV – i.e., a Heavy Duty POV is covered for a beneficiary weighing 285 – 450 pounds; a Very Heavy Duty POV is covered for a beneficiary weighing 428 – 600 pounds.
   
   
8. Use of a POV will significantly improve the beneficiary’s ability to participate in MRADLs and the beneficiary will use it in the home.
   
   
9. The beneficiary has not expressed an unwillingness to use a POV in the home.

If a POV will be used inside the home and coverage criteria A-I are not met, it will be denied as not reasonable and necessary.

Group 2 POVs (K0806, K0807, K0808) have added capabilities that are not needed for use in the home. Therefore, if a Group 2 POV is provided it will be denied as not reasonable and necessary.

If a POV will only be used outside the home, see related Policy Article for information concerning noncoverage.

If coverage criterion 1 for K0013 is not met, the claim will be denied as not reasonable and necessary.

If coverage criterion 2 for K0013 is not met, the claim will be denied for incorrect coding (see related Policy Article for additional information).

A custom motorized/power wheelchair base is not reasonable and necessary if the expected duration of need for the chair is less than three months (e.g., post-operative recovery).

If the PWC base is not covered, then related accessories will be denied.


MISCELLANEOUS:

A POV or power wheelchair with Captain's Chair is not appropriate for a beneficiary who needs a separate wheelchair seat and/or back cushion. If a skin protection and/or positioning seat or back cushion that meets coverage criteria (see Wheelchair Seating LCD) is provided with a POV or a power wheelchair with Captain's Chair, the POV or PWC will be denied as not reasonable and necessary. (Refer to Wheelchair Seating LCD and Policy Article for information concerning coverage of general use, skin protection, or positioning cushions when they are provided with a POV or power wheelchair with Captain's Chair.)

For beneficiaries who do not have special skin protection or positioning needs, a power wheelchair with Captain’s Chair provides appropriate support. Therefore, if a general use cushion is provided with a power wheelchair with a sling/solid seat/back instead of Captain’s Chair, the wheelchair and the cushion(s) will be covered only if either criterion 1 or criterion 2 is met:

1. The cushion is provided with a covered power wheelchair base that is not available in a Captain’s Chair model – i.e., codes K0839, K0840, K0843, K0860, K0861, K0862, K0863, K0864, K0890, K0891; or
2. A skin protection and/or positioning seat or back cushion that meets coverage criteria is provided.

If one of these criteria is not met, both the power wheelchair with a sling/solid seat and the general use cushion will be denied as not reasonable and necessary.

If a heavy duty, very heavy duty, or extra heavy duty PWC or POV is provided and if the beneficiary’s weight is outside the range listed in criterion G or L above (i.e., for heavy duty – 285 – 450 pounds, for very heavy duty – 428 – 600 pounds, for extra heavy duty – 570 pounds or more), it will be denied as not reasonable and necessary.

Refer to the related Policy Article for information concerning coverage of Group 2 PWCs with seat elevators (K0830, K0831).

For PWCs that go through Advance Determination of Medicare Coverage (ADMC) or Prior Authorization (PA) and receive an affirmative determination, the delivery must be within 6 months following the determination.

An add-on to convert a manual wheelchair to a joystick-controlled power mobility device (E0983) or to a tiller-controlled power mobility device (E0984) will be denied as not reasonable and necessary.

Payment is made for only one wheelchair at a time. Backup chairs are denied as not reasonable and necessary.

One month's rental of a PWC or POV (K0462) is covered if a beneficiary-owned wheelchair is being repaired. Payment is based on the type of replacement device that is provided but will not exceed the rental allowance for the power mobility device that is being repaired.

A power mobility device will be denied as not reasonable and necessary if the underlying condition is reversible and the length of need is less than 3 months (e.g., following lower extremity surgery which limits ambulation).

A POV or PWC which has not been reviewed by the Pricing, Data Analysis, and Coding (PDAC) contractor or which has been reviewed by the PDAC and found not to meet the definition of a specific POV/PWC will be denied as not reasonable and necessary and should be coded as K0899.

GENERAL

An item/service is correctly coded when it meets all the coding guidelines listed in CMS HCPCS guidelines, LCDs, LCD-related Policy Articles, or DME MAC articles. Claims that do not meet coding guidelines shall be denied as not reasonable and necessary/incorrectly coded.

Proof of delivery (POD) is a Supplier Standard and DMEPOS suppliers are required to maintain POD documentation in their files. Proof of delivery documentation must be made available to the Medicare contractor upon request. All services that do not have appropriate proof of delivery from the supplier shall be denied as not reasonable and necessary.

DOCUMENTATION REQUIREMENTS

Section 1833(e) of the Social Security Act precludes payment to any provider of services unless "there has been furnished such information as may be necessary in order to determine the amounts due such provider.” It is expected that the beneficiary's medical records will reflect the need for the care provided. The beneficiary's medical records include the treating practitioner's office records, hospital records, nursing home records, home health agency records, records from other healthcare professionals and test reports. This documentation must be available upon request.

GENERAL DOCUMENTATION REQUIREMENTS

In order to justify payment for DMEPOS items, suppliers must meet the following requirements:

• SWO

• Medical Record Information (including continued need/use if applicable)

• Correct Coding

• Proof of Delivery

Refer to the LCD-related Standard Documentation Requirements article, located at the bottom of this policy under the Related Local Coverage Documents section for additional information regarding these requirements.

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

Refer to the DME MAC web sites for additional bulletin articles and other publications related to this LCD.


POLICY SPECIFIC DOCUMENTATION REQUIREMENTS

Items covered in this LCD have additional policy-specific requirements that must be met prior to Medicare reimbursement.

Refer to the LCD-related Policy article, located at the bottom of this policy under the Related Local Coverage Documents section for additional information.

As a condition of payment pursuant to 42 CFR 410.38, Power Mobility Devices (PMDs) require a standard written order prior to delivery (WOPD) for the base item. If the supplier does not receive the order/prescription for the base item prior to delivery, the claim will be denied as not reasonable and necessary.

The WOPD for the base item may only be written after the completion of the face-to-face encounter requirements. Pursuant to the Social Security Act, Title XVIII, §1834(a)(1)(E)(iv), the treating practitioner who completes the face-to-face requirements must be the same practitioner who writes the order/prescription for the PMD (base item).

A supplier may provide a template to the treating practitioner for their use in creating the WOPD for the base item. Such a template may list the elements of a WOPD, but the supplier must not fill in or complete any of these elements.

An SWO is required prior to claim submission for all options, accessories, and/or supplies that are separately billed in addition to the base. This SWO obtained prior to claim submission, may be prepared by someone other than a treating practitioner. If someone other than a treating practitioner prepares the SWO for separately billed options, accessories, and/or supplies, a treating practitioner must review and sign the order.

The treating practitioner who reviews and signs the SWO for separately billable options, accessories, and/or supplies does not need to be the same treating practitioner who completed the WOPD for the PMD base and conducted the face-to-face encounter. In this situation, the treating practitioner who orders the options, accessories, and/or supplies must:

• Verify that a qualifying face-to-face encounter occurred within 6-months prior to the date of the WOPD for the base item; and,
• Have documentation of the qualifying face-to-face encounter that was conducted for the base item;
• Review and sign their order.

Refer to the Policy Article NON-MEDICAL NECESSITY COVERAGE AND PAYMENT RULES section for additional information.

FACE-TO-FACE ENCOUNTER:

The face-to-face encounter must be conducted within six (6) months prior to the order date on the WOPD for the PMD (base item).

The report of the face-to-face encounter (see Policy Article) should provide information relating to the following questions.

The report should provide pertinent information about the following elements, but may include other details. Each element would not have to be addressed in every evaluation.

• History of the present condition(s) and past medical history that is relevant to mobility needs
  
  • Symptoms that limit ambulation
  • Diagnoses that are responsible for these symptoms
  • Medications or other treatment for these symptoms
  • Progression of ambulation difficulty over time
  • Other diagnoses that may relate to ambulatory problems
  • How far the beneficiary can walk without stopping
  • Pace of ambulation
  • What ambulatory assistance (cane, walker, wheelchair, caregiver) is currently used
  • What has changed to now require use of a power mobility device
  • Ability to stand up from a seated position without assistance
  • Description of the home setting and the ability to perform activities of daily living in the home
• Physical examination that is relevant to mobility needs
  
  • Weight and height
  • Cardiopulmonary examination
  • Musculoskeletal examination
    
    • Arm and leg strength and range of motion
  • Neurological examination
    
    • Gait
    • Balance and coordination

The evaluation should be tailored to the individual beneficiary’s conditions. The history should paint a picture of the beneficiary’s functional abilities and limitations on a typical day. It should contain as much objective data as possible. The physical examination should be focused on the body systems that are responsible for the beneficiary’s ambulatory difficulty or impact on the beneficiary's ambulatory ability.

The written report of this encounter must be available upon request.

Practitioners shall document the encounter in a detailed narrative note in their charts in the format that they use for other entries. The note must clearly indicate that a major reason for the visit was a mobility encounter.

Many suppliers have created forms which have not been approved by CMS which they send to practitioners and ask them to complete. Even if the treating practitioner completes this type of form and puts it in his/her chart, this supplier-generated form is not a substitute for the comprehensive medical record as noted above. Suppliers are encouraged to help educate practitioners on the type of information that is needed to document a beneficiary's mobility needs.

Practitioners shall also provide reports of pertinent laboratory tests, x-rays, and/or other diagnostic tests (e.g., pulmonary function tests, cardiac stress test, electromyogram, etc.) performed in the course of management of the beneficiary. Upon request, suppliers shall provide notes from prior visits to give a historical perspective of the progression of disease over time and to corroborate the information in the face-to-face encounter.

If the report of a licensed/certified medical professional (LCMP) examination is to be considered as part of the face-to-face encounter (see Policy Article), there must be a signed and dated attestation by the supplier or LCMP that the LCMP has no financial relationship with the supplier. (Note: Evaluations performed by an LCMP who has a financial relationship with the supplier may be submitted to provide additional clinical information, but will not be considered as part of the face-to-face encounter by the treating practitioner.)

Although beneficiaries who qualify for coverage of a power mobility device may use that device outside the home, because Medicare’s coverage of a wheelchair or POV is determined solely by the beneficiary’s mobility needs within the home, the encounter must clearly distinguish the beneficiary’s abilities and needs within the home from any additional needs for use outside the home.

SPECIALTY EVALUATION:

The specialty evaluation that is required for beneficiary's who receive a Group 2 Single Power Option or Multiple Power Options PWC, any Group 3 PWC, or a push-rim activated power assist device is in addition to the requirement for the face-to-face encounter. The specialty evaluation provides detailed information explaining why each specific option or accessory – i.e., power seating system, alternate drive control interface, or push-rim activated power assist – is needed to address the beneficiary’s mobility limitation. There must be a written report of this evaluation available on request.

HOME ASSESSMENT:

Prior to or at the time of delivery of a POV or PWC, the supplier or practitioner must perform an on-site evaluation of the beneficiary’s home to verify that the beneficiary can adequately maneuver the device that is provided considering physical layout, doorway width, doorway thresholds, and surfaces. There must be a written report of this evaluation available on request.
