How to Appeal a Durable Medical Equipment (DME) Denial

Insurance denials for durable medical equipment (DME) are extremely common. Whether it's a wheelchair, CPAP machine, hospital bed, or prosthetic device, this guide walks you through every step of the appeal process.

Common Reasons DME Is Denied

  • Not deemed medically necessary
  • Documentation doesn't meet coverage criteria
  • Prior authorization wasn't obtained
  • Equipment considered convenience rather than medical need
  • Supplier isn't contracted with your plan

Building Your Appeal

Step 1: Understand the Denial

Read the denial letter carefully. Identify the specific reason code and policy section cited.

Step 2: Gather Documentation

  • Prescription from your physician
  • Letter of medical necessity detailing your condition
  • Clinical notes describing functional limitations
  • Any test results (e.g., sleep study for CPAP, mobility assessment for wheelchair)
  • Photographs if applicable

Step 3: Meet Coverage Criteria

Review your plan's DME coverage policy. Then specifically address each criterion in your appeal:

  • Diagnosis matches covered conditions
  • Equipment is the most appropriate option
  • Equipment will be used in the home
  • Expected duration of need

Step 4: Submit the Appeal

Include the appeal letter, LMN, supporting documentation, and a copy of the denial letter. Send via certified mail and keep copies.

Medicare-Specific DME Rules

For Medicare beneficiaries, DME must be ordered by the treating physician, supplied by a Medicare-enrolled supplier, and meet specific coverage criteria in Local Coverage Determinations (LCDs).
