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))
