DefinitionWhat is medical billing? The complete process
Medical billing is the end-to-end process of submitting and following up on insurance claims so a healthcare provider is paid for services rendered. It spans front-end work — eligibility verification, prior authorization, and charge capture — and back-end work — coding, claim submission via EDI 837, denial management, and payment posting via ERA (EDI 835).
That definition sets the border for everything below. Medical billing is one phase of revenue cycle management — the work that turns a documented encounter into collected revenue. It splits cleanly into a front end and a back end.
Front-end billing
Everything before the claim leaves the office: insurance eligibility verification (the 270/271 EDI transaction), prior authorization, demographic capture, and charge capture from the encounter. Errors caught here — a wrong member ID, a missing authorization — are denials that never happen.
Back-end billing
Everything after the encounter is documented: medical coding, claim scrubbing, submission to the clearinghouse, payer follow-up, denial management, and payment posting. Back-end accuracy determines how much of the billed amount the practice actually collects.
Two standardized claim forms carry nearly every claim. The form depends on who rendered the service, and the version matters — RevalonMD verifies the current form version before submission.
A billing operation is judged on a handful of metrics. Here is how RevalonMD’s targets sit against the MGMA and HFMA benchmarks and the national average — the comparison most billing pages never publish.
Every error caught before submission is a denial that never happens.RevalonMD’s certified team verifies eligibility, codes to current code years, and scrubs every claim before it reaches a payer. Book a free billing audit →
