  • Treating practitioner name or NPI (42 CFR 410.38(d)(1)(i)(E))
  • Treating practitioner signature (42 CFR 410.38(d)(1)(i)(F))

Amounts are the Medicare DMEPOS fee-schedule allowables effective October 2026 (CMS DMEPOS Fee Schedule October 2026 (DME26-D)). Medicare typically pays 80% of the allowable after the Part B deductible; the patient owes 20%. A 2% sequestration reduction applies to the Medicare share. Former competitive-bidding-area adjustments and non-continental rates can differ — verify with your DME MAC.

Unit limit (MUE)

Medicare's Medically Unlikely Edit caps L5505 at 2 units per date of service (absolute). Units above the MUE deny — typically as CO-151. Rationale: Anatomic Consideration.
