How Highmark denies dme — wheelchairs, prosthetics, orthotics — and how to counter it

Where Highmark pushes back: 1) No documentation of patient benefit / no improvement; 2) Home not documented accessible; 3) Pressure surface not justified.

Counter-arguments that hold up: Cite Jimmo v. Sebelius (2013) directly — improvement standard impermissible; equipment to maintain function or prevent deterioration is covered. Submit ATP home assessment. NPUAP staging documentation for ulcers + DTI; for Group 2 cite multiple Stage 2 + comprehensive program; for Group 3 cite Stage 3-4 + Group 2 failure.

How to submit the appeal to Highmark

1. Read the denial letter — note the exact denial reason code and the appeal deadline (180 days from the date on the letter).
2. Gather supporting documentation: physician letter of medical necessity, relevant clinical notes, peer-reviewed citations supporting the treatment for your indication, and the policy or coverage document Highmark cited in the denial.
3. File the appeal through Highmark's portal (members: https://www.highmark.com ; providers: https://www.highmark.com/provider). Standard decision returns within 30 days; expedited urgent appeals return within 72 hours.
4. If denied again, request external review by an independent reviewer within 4 months of the final internal denial. In PA, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
