Power Wheelchair Group 2 denied as non-formulary by UnitedHealthcare?

UnitedHealthcare's Commercial policy states that mobility devices including manual wheelchairs, electric wheelchairs, transfer chairs, scooters/power-operated vehicles (POVs), canes, and walkers are a covered health care service when medically necessary. The policy applies the Medicare DME MAC LCD for Power Mobility Devices (L33789) criteria, which require that 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, where the mobility limitation prevents the beneficiary from accomplishing an MRADL entirely, places the beneficiary at heightened risk of morbidity or mortality, or prevents completion within a reasonable time frame. The beneficiary's mobility limitation cannot be sufficiently and safely resolved by an appropriately fitted cane or walker, and 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. For a Group 2 Single Power Option PWC (K0835–K0840), all basic coverage criteria (a)–(e) must be met, plus the beneficiary requires a drive control interface other than a hand or chin-operated standard proportional joystick (e.g., head control, sip and puff, switch control), OR meets coverage criteria for a power tilt or power recline seating system being used on the wheelchair, AND has had a specialty evaluation performed by a licensed/certified medical professional (PT, OT, or practitioner) with specific training and experience in rehabilitation wheelchair evaluations documenting medical necessity. The wheelchair must be provided by a supplier that employs a RESNA-certified Assistive Technology Professional (ATP) who specializes in wheelchairs and has direct, in-person involvement in the wheelchair selection. Section 6407 of the ACA requires a face-to-face encounter, documented by a physician (or NP, PA, or CNS), occurring within the 6 months before the order is written for the DME. Weight-class criteria apply: a Heavy Duty PWC is covered for beneficiaries weighing 285–450 pounds, Very Heavy Duty for 428–600 pounds, and Extra Heavy Duty for 570 pounds or more. Payment is made for only one wheelchair at a time; backup chairs are denied as not reasonable and necessary.

- **Document in-home MRADL impairment in detail** — Provide specific examples of how the member cannot independently/safely complete toileting, feeding, dressing, grooming, or bathing in the home, mapping directly to the LCD MRADL definition: a mobility limitation that prevents accomplishment of an MRADL, places the beneficiary at heightened risk of morbidity/mortality, or prevents completion within a reasonable time frame. - **Demonstrate failure of lesser alternatives** — Include PT/OT trial documentation showing that the beneficiary lacks sufficient upper extremity function to self-propel an optimally-configured manual wheelchair in the home to perform MRADLs during a typical day due to weakness, fatigue, pain, ROM limits, or absent extremities, satisfying LCD basic criterion C. - **Submit a compliant specialty evaluation and ATP attestation** — Provide the LCMP/PT/OT evaluation with the no-financial-relationship attestation per the requirement of a signed and dated attestation by the supplier or LCMP that the LCMP has no financial relationship with the supplier , plus documentation that the wheelchair is provided by a supplier that employs a RESNA-certified Assistive Technology Professional (ATP) who specializes in wheelchairs and has direct, in-person involvement in the wheelchair selection. - **Justify the Group 2 power option upgrade** — For K0835–K0840, document either a non-standard drive control need (head control, sip-and-puff, switch) OR concurrent need for a power tilt/recline system per the LCD requirement that the beneficiary requires a drive control interface other than a hand or chin-operated standard proportional joystick, or meets coverage criteria for a power tilt or power recline seating system being used on the wheelchair. - **Provide a timely 7-element order and face-to-face note** — Submit the in-window F2F note and order; per the LCD policy article, the 7-element order must be received by the supplier within 45 days after completion of the face-to-face examination , and per CMS, the encounter must occur within the 6 months before the order is written. - **Verify accurate weight-class coding** — Confirm the member's weight aligns with the prescribed class boundaries set by the LCD: Heavy Duty 285–450 lb, Very Heavy Duty 428–600 lb, and Extra Heavy Duty 570 lb or more , and amend the HCPCS code if a misclassification triggered the denial. - **Cite clinical/professional standards** — Reference RESNA's position papers on the application of power wheelchairs and seat-elevation/tilt systems, and AOTA/APTA wheelchair assessment guidelines, to support the medical necessity narrative that mirrors LCD L33789 — the framework UnitedHealthcare explicitly adopts via its Mobility Devices policy and the DME MAC LCD for Power Mobility Devices (L33789).

## UnitedHealthcare Medicare Advantage "Non-Formulary" Denials on Group 2 Power Wheelchairs (K0835–K0843)

The "non-formulary" label is a misnomer here. Durable medical equipment does not sit on a Part D formulary — Group 2 PMDs are Part B benefits administered by UHC Medicare Advantage under 42 CFR §422.101(b), which obligates the plan to cover any item Original Medicare would cover. When UHC's denial letter says "non-formulary" or "not on covered list," what the plan is almost always doing is substituting an internal coverage grid (the UHC MA Coverage Summary: DME, Prosthetics, Orthotics… Grid) for the controlling DME MAC LCD L33789. That substitution is appealable, and in most cases reversible, because §422.101(b)(2) forbids MA plans from applying coverage criteria more restrictive than the National Coverage Determination / LCD framework unless internal criteria are publicly posted and based on current clinical evidence (CMS-4201-F, effective 2024).

Where these denials originate. UHC routes PMD requests through Optum (the delegated UM vendor) and increasingly through naviHealth/Home & Community for post-acute mobility. Optum reviewers frequently downcode a K0835–K0843 request to a K0823 Group 2 standard, or deny entirely, citing "not on covered DME list," "alternative item available," or "failed step to manual/scooter." None of those are valid LCD L33789 criteria. The LCD requires only criteria (A)–(C) plus the Group 2 add-ons (specialty PT/OT evaluation, non-standard drive control or power seating, and for K0841–K0843 a neurological/myopathic/congenital etiology or vent dependence).

The procedural lever. File a Part C reconsideration under 42 CFR §422.582 within 60 days, and explicitly invoke §422.566(b) (organization determination scope) and §422.101(b). Demand the plan's internal coverage criteria in writing under §422.101(b)(6) — if UHC cannot produce evidence-based, publicly posted criteria stricter than L33789, the denial collapses. Attach the seven-element order, the LCMP (PT/OT) specialty evaluation, the home assessment, and a face-to-face note dated within 45 days prior to the SWO. Cite Wit v. UBH (N.D. Cal. 2019, aff'd in relevant part 9th Cir. 2023) for the principle that an insurer may not substitute internally drafted utilization criteria for generally accepted standards of care — directly applicable to Optum-delegated UM.

If reconsideration fails, the case auto-forwards to the Part C IRE (Maximus Federal). Maximus reverses UHC Group 2 PMD denials at a notably high rate when the LCMP evaluation is complete and the home accessibility narrative is documented. Beyond IRE: ALJ hearing (AIC $190 in 2026), Medicare Appeals Council, then federal district court under 42 USC §1395w-22(g)(5).

Tactical tip: Before filing, pull UHC's specific Coverage Summary version cited on the denial and line-item compare it against LCD L33789 §III. Any criterion in the UHC grid that adds a step (e.g., "trial of K0823 required," "scooter must fail first," "weight redundancy documentation") that is not in L33789 is a §422.101(b) violation — flag each one in the appeal letter as an ultra vires restriction and request the denial be vacated on that basis alone, separate from the clinical merits.
