Power Mobility Documentation and the Face-to-Face Requirement
A 68-year-old woman with advanced rheumatoid arthritis and severe hand deformities requests a power wheelchair. She lives alone in a small apartment with 30-inch doorways and a 4-inch threshold at the entry. Her physician's note says she 'cannot walk more than a few steps' and 'needs a power chair for mobility.' There is no 7-element order, no face-to-face encounter note specific to the wheelchair, and no mobility evaluation by a physical or occupational therapist. The supplier's rehab specialist believes a complex power wheelchair with power seating is needed because of her hand deformities and seating needs. The patient's Medicare Part B coverage is active, and she has secondary insurance.
1. Identify the documentation gaps and explain why each matters for this power mobility device claim.

Several gaps exist. First, there is no detailed written order containing the seven required elements - the beneficiary's name, the item ordered, the date of the order, the treating practitioner's signature, the description of the item, the quantity, and the date of the face-to-face encounter. Without a compliant order, the claim is vulnerable to denial.
Second, there is no wheelchair-specific face-to-face encounter note documenting the patient's mobility limitation, the physical exam, and the reason a power wheelchair is needed rather than a cane, walker, or manual wheelchair. A generic note saying she 'cannot walk more than a few steps' is not enough. Third, there is no mobility evaluation, which is typically required for a complex power wheelchair and should be performed by a qualified clinician such as a PT or OT. The evaluation should address her ability to operate the controls, seating and positioning needs, and the home environment. Fourth, the home assessment matters: 30-inch doorways and a 4-inch threshold may affect whether the specific device can be used in the home, and the supplier should document that the device fits and can be used there.
2. The supplier wants to deliver the complex power wheelchair next week. What sequence should the supplier follow, and what should it tell the patient about timing?

The supplier should not deliver and bill until the documentation is complete. The sequence is: (1) the treating practitioner performs and documents a wheelchair-specific face-to-face encounter; (2) a qualified clinician performs a mobility evaluation, including a home assessment or a documented evaluation of the home environment; (3) the practitioner writes a detailed order with the seven elements and the specific equipment; (4) the supplier confirms the patient can operate and benefit from the device, documents the home assessment, and verifies coverage and prior authorization requirements; (5) the supplier delivers, fits, and trains the patient, documenting all of it; (6) the supplier bills with the order, encounter note, evaluation, and delivery documentation.
The supplier should tell the patient the delivery will likely take several weeks because the evaluation and order must be completed first. Promising next-week delivery before documentation exists sets up a denial and a dissatisfied patient. If the patient's secondary insurance requires prior authorization, that adds time.
3. The home assessment finds the 4-inch threshold and 30-inch doorways. How should this affect the equipment selection and the claim?
Read the worked answer
The home assessment is part of the justification for the device. A complex power wheelchair that cannot be used in the home may not be medically necessary for this patient, and the supplier should consider a device that fits the environment or document why the selected device is appropriate. The supplier should measure the doorways, the threshold, turning space, and the bathroom access, and record those measurements.
If the selected device cannot navigate the threshold, the supplier should discuss alternatives with the clinician - a different base, ramps, or a modification - and document the discussion. The claim should include the home assessment showing the device can be used in the home. If the patient cannot use the device in the home, the supplier should not bill it as medically necessary without addressing the discrepancy, because the payer may deny on that basis. The supplier should also confirm the patient can safely operate the controls given her hand deformities, and document any specialized control interface.
