Article Guidance

Article Text

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”).

High frequency chest wall oscillation devices are covered under the Durable Medical Equipment benefit (Social Security Act §1861(s)(6)). In order for a beneficiary’s equipment 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, there are specific statutory payment policy requirements, discussed below, that also must be met.

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.

The diagnosis code that justifies the need for these items must be included on the claim.


MODIFIERS

KX, GA, AND GZ MODIFIERS:

Suppliers must add a KX modifier to codes for an HFCWO device and accessories only if all of the criteria in the Coverage Indications, Limitations, and/or Medical Necessity section of the related LCD have been met.

If all of the criteria in the Coverage Indications, Limitations and/or Medical Necessity section of the related LCD have not been met, the GA or GZ modifier must be added to the code. When there is an expectation of a denial as not reasonable and necessary, suppliers must enter GA on the claim line if they have obtained a properly executed Advance Beneficiary Notice (ABN) or GZ if they have not obtained a valid ABN.

There must be information in the beneficiary’s medical record that describes in detail the underlying medical condition(s) that cause the accumulation of pulmonary secretions, the treatment interventions (for example, chest physiotherapy, postural drainage, medications used, mechanical modalities such as in-exsufflation devices (not all-inclusive)) and the effectiveness of the treatment. This information must be available upon request.

Claim lines billed without a KX, GA, or GZ modifier will be rejected as missing information.

CODING GUIDELINES

HCPCS code E0483 (HIGH FREQUENCY CHEST WALL OSCILLATION SYSTEM, WITH FULL ANTERIOR AND/OR POSTERIOR THORACIC REGION RECEIVING SIMULTANEOUS EXTERNAL OSCILLATION, INCLUDES ALL ACCESSORIES AND SUPPLIES, EACH) devices (HFCWO) use positive and negative pressure changes to augment peripheral and tracheal mucus movement towards the airway opening. This function is performed by extra-thoracic oscillations generated by forces external to the respiratory system. External chest wall oscillations are applied using a vest worn around the torso, which vibrates at variable frequencies and intensities, as set by the operator. E0483 devices may use differing technologies, e.g. air-pulse generators and an inflatable vest, an array of mechanical oscillators in a vest providing synchronized oscillation. E0483 is all-inclusive regardless of the technique used to produce HFCWO. 

HCPCS code A7025 (HIGH FREQUENCY CHEST WALL OSCILLATION SYSTEM VEST, REPLACEMENT FOR USE WITH PATIENT OWNED EQUIPMENT, EACH) describes a complete replacement vest. This includes all components such as mechanical oscillators, electrical componentry, inflatable air sacs, connectors. Separate billing of vest components when an entire vest is replaced is incorrect coding – unbundling.

HCPCS code A7026 (HIGH FREQUENCY CHEST WALL OSCILLATION SYSTEM HOSE, REPLACEMENT FOR USE WITH PATIENT OWNED EQUIPMENT, EACH) describes the tubing used with an air pulse generator type of HFCWO device.

HCPCS code E0483 describes a complete system. Separate billing of A7025 and/or A7026 in combination with E0483 is incorrect coding – unbundling.

Suppliers should contact the Pricing, Data Analysis, and Coding (PDAC) contractor for guidance on the correct coding of these items.
