Revenue Cycle Management and Reimbursement
The revenue cycle
Revenue cycle management (RCM) spans pre-service, service, and post-service activities: scheduling, registration, eligibility verification, coding, charge capture, claim submission, and denial management. Candidates must understand charge capture accuracy, clean claim rates, and the impact of coding errors on reimbursement. Know the difference between fee-for-service, capitation, and value-based payment models.
Payers and reimbursement methods
Understand Medicare (Part A/B), Medicaid, and commercial payers. Familiarize yourself with DRG-based inpatient payment, APC-based outpatient payment, and RVU-based physician payment. Know the role of NCCI edits in preventing improper unbundling, and the importance of medical necessity in claim approval.
Traps to watch
- Assuming a code is payable simply because it is valid.
- Confusing DRG (inpatient) with APC (outpatient).
- Overlooking medical necessity documentation.
- Ignoring NCCI edits and bundling rules.
- Misunderstanding capitation (fixed per-member payment) versus fee-for-service.
Rule of thumb
Payment follows documentation + medical necessity + correct coding. A clean claim is one that passes edits and matches the payer's rules on the first submission.
Worked example
An inpatient claim is grouped into a DRG based on the principal diagnosis, procedures, and complications. An outpatient claim is grouped into an APC. The same procedure coded in the wrong setting can change the payment methodology entirely.
