Coverage, in CMS's words
Local coverage indication
Leg extensions (E0158) are covered only for beneficiaries 6 feet tall or more. A Standard Written Order (SWO) must be communicated to the supplier before a claim is submitted. If the supplier bills for an item addressed in this policy without first receiving a completed SWO, the claim shall be denied as not reasonable and necessary. For Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) base items that require a Written Order Prior to Delivery (WOPD), the supplier must have received a signed SWO before the DMEPOS item is delivered to a beneficiary. If a supplier delivers a DMEPOS item without first receiving a WOPD, the claim shall be denied as not reasonable and necessary. Refer to the LCD-related Policy Article, located at the bottom of this policy under the Related Local Coverage Documents section. For DMEPOS base items that require a WOPD, and also require separately billed associated options, accessories, and/or supplies, the supplier must have received a WOPD which lists the base item and which may list all the associated options, accessories, and/or supplies that are separately billed prior to the delivery of the items. In this scenario, if the supplier separately bills for associated options, accessories, and/or supplies without first receiving a completed and signed WOPD of the base item prior to delivery, the claim(s) shall be denied as not reasonable and necessary. 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.

What NCD 280.3 says the item is
A. General The Centers for Medicare & Medicaid Services (CMS) addresses numerous items that it terms “mobility assistive equipment” (MAE) and includes within that category canes, crutches, walkers, manual wheelchairs, power wheelchairs, and scooters. This list, however, is not exhaustive. Medicare beneficiaries may require mobility assistance for a variety of reasons and for varying durations because the etiology of the disability may be due to a congenital cause, injury, or disease. Thus, some beneficiaries experiencing temporary disability may need mobility assistance on a short-term basis, while in contrast, those living with chronic conditions or enduring disabilities will require mobility assistance on a permanent basis. Medicare beneficiaries who depend upon mobility assistance are found in varied living situations.
National coverage indication, NCD 280.3
B. Nationally Covered Indications Effective May 5, 2005, CMS finds that the evidence is adequate to determine that MAE is reasonable and necessary for beneficiaries who have a personal mobility deficit sufficient to impair their participation in mobility-related activities of daily living (MRADLs) such as toileting, feeding, dressing, grooming, and bathing in customary locations within the home. Determination of the presence of a mobility deficit will be made by an algorithmic process, Clinical Criteria for MAE Coverage, to provide the appropriate MAE to correct the mobility deficit. Clinical Criteria for MAE Coverage The beneficiary, the beneficiary’s family or other caregiver, or a clinician, will usually initiate the discussion and consideration of MAE use. Sequential consideration of the questions below provides clinical guidance for the coverage of equipment of appropriate type and complexity to restore the beneficiary’s ability to participate in MRADLs such as toileting, feeding, dressing, grooming, and bathing in customary locations in the home. These questions correspond to the numbered decision points on the accompanying flow chart.

From A55426, Standard Documentation Requirements for All Claims Submitted to DME MACs
GENERAL There are numerous CMS manual requirements, reasonable and necessary (R&N) requirements, benefit category, and other statutory and regulatory requirements that must be met in order for payment to be justified. In the event of a claim review, a DMEPOS supplier must provide sufficient information to demonstrate that the applicable criteria have been met thus justifying payment. Before submitting a claim to Medicare, the DMEPOS supplier must have on file an SWO, a WOPD (if applicable), information from the treating practitioner concerning the patient's diagnosis, and any information required for the use of specific
