Revenue Cycle and Reimbursement
What the exam tests
Revenue cycle knowledge ties coding to payment. You should understand the front-end (registration, eligibility), mid-cycle (coding, charge capture), and back-end (billing, denials, collections) processes, plus the key reimbursement methodologies that apply to outpatient services.
Concepts to master
- Charge capture: accurate translation of services into billable codes; missed charges and duplicate charges both harm revenue integrity.
- Payers: Medicare, Medicaid, commercial, and managed care; each has different rules and timely filing limits.
- Reimbursement methods: fee schedule, APC/OPPS, and capitation; know that Medicare physician payment uses the MPFS (RVUs × conversion factor).
- Denials management: root-cause analysis of denials (eligibility, coding, medical necessity, timely filing) and the appeals process.
- Key metrics: clean claim rate, days in A/R, denial rate, and first-pass resolution rate.
Traps in questions
Questions may test the difference between a denial and a rejection (rejections are front-end edits; denials are payer decisions). Another trap is assuming a coder controls charge entry - coders assign codes, but charge capture is a broader process. Watch for items that confuse the conversion factor with the payment amount.
Rule of thumb
Payment = RVU × conversion factor for physician services; for facilities, payment follows APC grouping. A clean claim the first time is the cheapest claim.
