Order readiness — what the written order must contain

Every Medicare DMEPOS claim needs a Standard Written Order with all six elements (42 CFR 410.38(d)):

  • Beneficiary name or Medicare Beneficiary Identifier (MBI) (42 CFR 410.38(d)(1)(i)(A))
  • General description of the item (42 CFR 410.38(d)(1)(i)(B))
  • Quantity to be dispensed, if applicable (42 CFR 410.38(d)(1)(i)(C))
  • Order date (42 CFR 410.38(d)(1)(i)(D))
  • Treating practitioner name or NPI (42 CFR 410.38(d)(1)(i)(E))
  • Treating practitioner signature (42 CFR 410.38(d)(1)(i)(F))

Not on the F2F/WOPD list (CMS Required F2F & WOPD List — 83 items in force on 2026-10-26; 22 more from 2026-10-28; sources: CMS list effective 2026-04-13 (91 FR 1250), CMS-6109-N (91 FR 47972)). The standard written order must reach the supplier before claim submission.

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 K0050 at 2 units per date of service (clinical). Units above the MUE deny — typically as CO-151. Rationale: Nature of Equipment.
