DME billing is a big part of medical billing and coding. HCPCS Level II codes capture non-physician services, supplies and durable medical equipment. MedCare MSO is a certified DME billing company that knows the unique coding requirements of DME. Partner with us to get paid more, increase patient satisfaction and focus on what matters most patient care.
CMS updates HCPCS Level II codes for DME in medical billing every year medical billers need to update codes These complexities can impact claims big time and requires attention to detail.
Accurate documentation is the foundation of DME billing compliance. This includes:
Detailed physician orders: also known as a Standard Written Order (SWO) or Detailed Written Order (DWO), is a document that confirms what a physician has prescribed for a patient. Must be signed, dated, specify the exact DME, patient’s diagnosis, patient information, physician information, length of need and any special instruction. For DME drugs under the DME benefit the order must also specify: drug name, dosage/concentration, duration, quantity and refills.
The detailed physician order acts as a bridge between the physician’s prescription and the DME supplier’s billing process, so the right equipment gets to the right patient and the claim is properly supported for reimbursement.
Streamlined prior authorization (PA) in Durable Medical Equipment (DME) billing refers to optimizing the process of obtaining approvals from insurance payers before providing DME items to patients.
Also using outdated coding resources and not meeting specific payer requirements contributes to denials.

MedCareMSO pairs DMEPOS-specialized expertise with end-to-end revenue cycle management built for equipment suppliers. We handle the details that make or break DME claims accurate HCPCS Level II coding, matched modifiers (RR, NU, UE, KX), complete SWO and Proof of Delivery documentation, prior authorization tracking, and root-cause denial management. The result is a higher clean claim rate, fewer recoupments, and lower days in A/R, plus PECOS, CMS-855S, and DMEPOS accreditation support to keep you enrollment- and audit-ready.
Durable medical equipment (DME) billing is the process of securing reimbursement from Medicare, Medicaid, and commercial payers for reusable, home-use medical equipment such as wheelchairs, CPAP machines, oxygen concentrators, and hospital beds. Unlike standard medical billing, DME billing relies on HCPCS Level II codes (not CPT), and involves rental periods, capped allowances, proof of delivery, and strict medical necessity documentation. Because DMEPOS is one of the most audited claim categories in US healthcare, accuracy across coding, modifiers, and documentation is what keeps claims paid.
A payable DME claim requires a Standard Written Order (SWO) signed by the treating practitioner, documented medical necessity, and a Proof of Delivery (POD) confirming the patient received the equipment. Higher-cost items like oxygen and power mobility also require a face-to-face encounter and, in many cases, Written Order Prior to Delivery (WOPD). Missing or incomplete documentation is the leading cause of DME denials and audit takebacks, so MedCareMSO verifies every required document before a claim goes out.
DME billing uses HCPCS Level II codes mostly the E series (e.g., E0601 for a CPAP device, E1390 for an oxygen concentrator) and the K series for power mobility (e.g., K0813). Modifiers are mandatory and must match how the item is supplied: RR for rental, NU for new purchase, UE for used equipment, and KX to confirm coverage criteria are met. Advance Beneficiary Notice modifiers (GA, GZ, GY) signal expected denials and determine whether the patient can be billed for misusing them, such as GZ instead of GA, forfeits your ability to collect from the patient.
DME is billed as either a rental or a purchase, and the modifier must reflect that RR for rental, NU for new purchase, UE for used. Many high-cost items are billed as capped rental: they bill monthly (with RR) for up to 13 months, after which ownership transfers to the patient, rather than as a one-time purchase. Getting the rental category, monthly cap, and modifier right is essential to avoid overpayment recoupments and denials.
Yes, MedCareMSO improves DME cash flow by fixing errors upstream and working every claim to payment. We combine real-time eligibility verification, accurate HCPCS coding with correct modifiers, complete SWO/POD documentation, prior authorization tracking, and proactive denial management with appeals. The result is a higher clean claim rate, fewer recoupments, and lower days in A/R with transparent KPI reporting on denial rate, aging, and net collections.
