The Medical Billing Claim Lifecycle

Follow a claim from scheduling and eligibility through coding, submission, adjudication, payment, denial, and follow-up.

Quick answer

A reliable claim starts before the encounter. Eligibility, authorization, documentation, coding, claim edits, payer routing, remittance posting, and follow-up are one connected control system.

Rules to know

  • Verify payer and benefit facts before service.
  • Code only from supported documentation.
  • Separate front-end rejection from post-adjudication denial.
  • Use the ERA to route each balance to the correct next action.

Operational workflow

  1. 01Confirm demographics, payer order, eligibility, and authorization.
  2. 02Capture complete documentation and charges.
  3. 03Assign supported diagnosis, procedure, modifier, POS, and unit data.
  4. 04Scrub and submit the correct professional or institutional transaction.
  5. 05Reconcile acknowledgments, claim status, ERA, payment, and patient responsibility.

Common failure modes

  • Treating a clearinghouse acceptance as payer acceptance.
  • Working denials without reading all group, reason, and remark codes.
  • Correcting one field without checking the rest of the claim context.
