The DME billing procedure is entirely different than that of the other medical billing and coding processes. DME has been classified under the HCPCS level II codes. These codes are of 5 digits and come in a combination of alphabets and numeric. Adhering to these codes requires domain-specific expertise. There are multiple steps involved in coding the DME billing. The process consists in getting the prescription from the medical practitioner, assigning the codes, and processing the billing for claims from the insurance payer. Finally, getting it distributed to the patient.
