Power wheelchair — group 2 denied as non-formulary by UnitedHealthcare?

Under UnitedHealthcare's Commercial medical policy, mobility devices including manual wheelchairs, electric wheelchairs, transfer chairs, scooters/power-operated vehicles (POV), canes, and walkers are a covered health care service when medically necessary. The policy aligns with CMS LCD L33789, which establishes that the beneficiary must have 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 limitation that prevents the beneficiary from accomplishing an MRADL entirely, places the beneficiary at heightened risk of morbidity or mortality, or prevents completing an MRADL within a reasonable time frame ; additionally, the 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. Use of a power wheelchair must significantly improve the beneficiary's ability to participate in MRADLs and the beneficiary will use it in the home (for severe cognitive/physical impairments, participation in MRADLs may require caregiver assistance), and the beneficiary has not expressed an unwillingness to use a power wheelchair in the home. For a Group 2 standard PWC, a Group 2 PWC (K0820, K0821, K0822, K0823, K0824, K0825, K0826, K0827, K0828, K0829) is covered if all of the coverage criteria (a)-(e) for a PWC are met and the wheelchair is appropriate for the beneficiary's weight. For a Group 2 Single Power Option PWC, all coverage criteria (a)-(e) must be met, plus the beneficiary meets coverage criteria for a power tilt or recline seating system OR requires a drive control interface other than a hand or chin-operated standard proportional joystick (examples include head control, sip and puff, switch control) , and a specialty evaluation must be performed by a licensed/certified medical professional (PT, OT, or practitioner with rehab wheelchair training) with no financial relationship with the supplier, and the wheelchair must be provided by a supplier that employs a RESNA-certified Assistive Technology Professional (ATP) with direct, in-person involvement in the wheelchair selection. DME has a reasonable useful lifetime (RUL) of 5 years , and payment is made for only one wheelchair at a time; backup chairs are denied as not reasonable and necessary.

- **Document MRADL impact in detail**: Provide a clinician note specifying which MRADLs (toileting, feeding, dressing, grooming, bathing) the patient cannot complete or completes only with heightened morbidity/mortality risk, directly mapping to the LCD L33789 definition of a qualifying mobility limitation . - **Stepwise rule-out of lesser devices**: Submit PT/OT documentation explaining why a cane, walker, and optimally-configured manual wheelchair each fail — addressing strength, endurance, ROM, coordination, pain, or upper-extremity deformity per the LCD's enumerated upper-extremity assessment factors (strength, endurance, range of motion, coordination, pain, deformity or absence of one or both upper extremities) . - **Provide compliant face-to-face and WOPD**: Attach the dated face-to-face mobility examination note and the signed Standard Written Order before delivery; cite Final Rule 1713's requirement of a face-to-face encounter and Written Order Prior to Delivery as satisfied. - **Include RESNA ATP and independent specialty evaluation**: For Group 2 Single Power Option chairs, include both the ATP credential attestation and the independent PT/OT specialty evaluation, satisfying the requirement that a licensed PT/OT with no financial relationship to the supplier perform the specialty evaluation and that a RESNA-certified ATP have direct involvement in wheelchair selection . - **Demonstrate in-home use**: Document home assessment showing adequate access between rooms and maneuvering space, and explicitly state the device will be used in the home to meet the requirement that the beneficiary's home provides adequate access and that the power wheelchair will significantly improve the beneficiary's ability to participate in MRADLs in the home . - **Justify Group 2 over Group 1**: If denied as needing only a Group 1, document the patient's weight against capacity limits or, for Single Power Option, the medical necessity of power tilt/recline (e.g., pressure ulcer risk, inability to perform a functional weight shift) or alternative drive control interface per LCD L33789 Group 2 Single Power Option criteria including need for non-standard drive control such as head control, sip and puff, or switch control . - **Replacement vs. repair**: For replacement requests, document the 5-year RUL and that the existing chair cannot be repaired or no longer meets the patient's needs, citing the 5-year reasonable useful lifetime standard and UHC's allowance for upgrades when the member's condition changes (e.g., impaired function necessitates an upgrade to a power wheelchair from a manual one) .

## Why UnitedHealthcare Denies a Group 2 Power Wheelchair as Non-Formulary

While "non-formulary" is a term most often associated with prescription drugs, UHC sometimes uses analogous coverage-tier or preferred-supplier logic for durable medical equipment (DME). A non-formulary denial for a Group 2 power wheelchair typically means that either: (a) the specific wheelchair model or manufacturer is not on UHC's preferred DME supplier list; (b) the supplier used to obtain the equipment is out-of-network; or (c) a specific component or accessory has been designated as non-covered. Understanding which of these applies to your denial is the first step in building your appeal.

## Why This Denial Is Appealable

If the denial is supplier-network based, you may have rights under UHC's out-of-network exception process — particularly if no in-network supplier in your area carries the specific equipment your clinician has determined is medically necessary. If the denial is model or feature-based, the appeal centers on why the specific equipment your prescriber ordered is medically necessary and why a covered alternative is clinically insufficient. UHC is required to have an exceptions process, and medical necessity can override formulary/tier restrictions when properly documented.

## Federal Appeal Framework

• Coverage exception / formulary exception request: File first. Explain why the non-formulary equipment is medically necessary and why the covered alternative is inadequate for your clinical needs.
• Internal appeal (ERISA §503 / state law): If the exception is denied, file a formal internal appeal within the timeline on your denial notice.
• External review (ACA §2719): A final internal denial is subject to independent external review within approximately four months.
• Network adequacy complaint: If no in-network supplier can provide the medically necessary equipment, UHC has a network-adequacy obligation. Filing a network adequacy complaint with your state's insurance commissioner can run parallel to your appeal.
• Expedited track: Request if your mobility needs create urgent functional or safety risk.

## Documentation to Gather

1. Prescriber specification of required equipment: A letter from your prescribing physician and/or therapist explaining why the specific model or component is medically necessary — not merely preferred — and why the covered/formulary alternative does not meet your functional needs. 2. Functional mobility assessment: Documenting the clinical basis for the specific equipment features required. 3. Supplier documentation: If the supplier is out-of-network, obtain documentation showing that no in-network supplier in your area stocks the medically necessary equipment. 4. UHC's preferred equipment or supplier list: Obtain this from member services so you understand exactly what UHC considers "formulary" for DME. 5. Diagnosis and chart records: Confirming the mobility-limiting diagnosis and current clinical status.

## Criteria-Mapping Structure

| UHC Non-Formulary Exception Criterion | Your Evidence | |---|---| | Covered alternative is clinically inadequate | [Prescriber/therapist letter with functional comparison] | | Requested equipment is medically necessary | [Face-to-face eval, therapist assessment, Rx letter] | | No in-network supplier available (if applicable) | [Supplier search documentation, distances, availability] | | Diagnosis and functional need | [Chart records, diagnosis confirmation] |

If the denial is based on model/feature non-coverage rather than supplier network, focus the appeal entirely on clinical necessity — why this specific feature (e.g., power tilt, specific drive configuration) is required for your documented functional limitations, not merely preferred.
