Definition
DMEPOS is a Medicare Part B benefit category covering durable medical equipment (CPAP, oxygen, walkers, wheelchairs, hospital beds), prosthetics, orthotics, and supplies. Items are coded under HCPCS Level II, billed to one of four DME Medicare Administrative Contractors (DME MACs), and may be subject to Competitive Bidding pricing in designated areas. Suppliers must be enrolled, bonded, and accredited under 42 CFR 424 Subpart D. What the regulation says
Statutory authority: 42 USC 1395m. Coding: HCPCS Level II (CMS-maintained). Coverage: National Coverage Determinations and DME MAC LCDs. Competitive Bidding: 42 CFR 414 Subpart F.
What this means in practice
DMEPOS Competitive Bidding has materially compressed pricing in covered categories and reshaped supplier-distribution economics. Surety bonds, accreditation (e.g., ACHC, BOC), and PECOS enrollment are the operational floor. Common pitfalls
- •Launching a DME product without confirming HCPCS coding and DME MAC coverage path.
- •Underestimating the operational burden of DMEPOS supplier accreditation and surety bond.
