What Is DME Billing?

DME billing (durable medical equipment billing) is the process of submitting claims to Medicare, Medicaid, and commercial insurance for medical equipment provided to patients — including wheelchairs, CPAP/BiPAP devices, hospital beds, prosthetics, orthotics, and diabetic supplies. DME billing uses HCPCS Level II codes and requires strict documentation including physician orders, certificates of medical necessity, and proof of delivery. Medicare DME billing is one of the most heavily audited claim types in healthcare — improper documentation is the #1 audit trigger.

DME Billing FAQ

DME billing (durable medical equipment billing) is the process of submitting claims to Medicare, Medicaid, and commercial insurers for medical equipment provided to patients. It uses HCPCS Level II codes and requires specific documentation — physician orders, certificates of medical necessity (CMN), and proof of delivery — to support medical necessity. Medicare DME claims are among the most audited claim types in the US, making documentation accuracy critical.
Medicare DME billing requires: (1) a detailed written order (DWO) from the ordering physician with specific elements required by the LCD; (2) a certificate of medical necessity (CMN) for equipment categories that require it (oxygen, hospital beds, wheelchairs, etc.); (3) proof of delivery (POD) signed by the patient or authorized representative; and (4) clinical documentation in the patient's medical record supporting medical necessity. Missing any of these is the leading cause of Medicare DME denials and audit recoupments.
PDAC (Pricing, Data Analysis and Coding) is the CMS contractor that provides HCPCS coding guidance and product classification for DME. PDAC coding decisions determine which HCPCS code applies to your specific equipment and therefore which fee schedule rate you receive. Using the wrong code — even for the same device at a different feature level — can result in significantly lower reimbursement or outright denial. PDAC-verified coding is essential for maximum legitimate reimbursement.
The most common DME denials are: (1) insufficient documentation of medical necessity — the most common and most preventable; (2) missing or expired CMN; (3) wrong HCPCS code for the equipment's feature set; (4) prior auth not obtained before delivery; (5) beneficiary not eligible for the billing frequency or quantity; (6) supplier not enrolled in competitive bidding for the patient's service area. Each has a specific prevention strategy — we address all of them systematically.
We manage the entire prior auth process for DME: preparing the authorization package with physician orders and clinical documentation, submitting to the payer, tracking status, appealing denials with additional clinical support, and renewing authorizations before expiration. For Medicare's Prior Authorization Program (PAP) items — power wheelchairs, pressure-reducing support surfaces, and others — we ensure PAP compliance so claims are not automatically denied after delivery.
