What is the revenue cycle?
The full financial lifecycle of a patient account — from scheduling to final payment. The goal: get providers accurately and fully paid for care, quickly and compliantly. It splits into three phases: front-end (before the visit), mid-cycle (coding & charges), and back-end (claims & collections).
Front, mid, and back office
| Phase | Covers |
|---|
| Front-end | Scheduling, registration, eligibility, prior authorization, patient estimates |
| Mid-cycle | Charge capture, coding, clinical documentation improvement (CDI), charge reconciliation |
| Back-end | Claims, payment posting, denials & appeals, A/R follow-up, collections |
The 13-step RCM lifecycle
| # | Step |
|---|
| 1 | Pre-registration & scheduling |
| 2 | Registration / patient intake |
| 3 | Insurance eligibility & verification |
| 4 | Prior authorization / referral |
| 5 | Encounter & documentation |
| 6 | Charge capture |
| 7 | Medical coding (ICD-10-CM, CPT, HCPCS) |
| 8 | Claim scrubbing & submission |
| 9 | Payer adjudication |
| 10 | Payment / remittance posting |
| 11 | Denial management & appeals |
| 12 | Patient statements & collections |
| 13 | Reporting & analytics |
Charge capture means recording every billable service and supply from the encounter. Coding means translating that documentation into ICD-10-CM (diagnoses) and CPT/HCPCS (services). Charge reconciliation confirms all services were actually captured and charged — accuracy here drives clean claims and fewer denials downstream.
Eligibility & authorization
| Term | What it means |
|---|
| Eligibility | Is the patient's coverage active, and what does it actually cover? |
| Verification | Confirming benefits, copay, deductible, and network status |
| Prior authorization | Payer approval required before a service is rendered |
| Referral | A PCP directing a patient to a specialist |
| ABN | Advance Beneficiary Notice — warns a Medicare patient they may owe if a service is denied |
Note: most denials start here — verifying eligibility and authorization up front prevents the majority of them.
Claim forms & key EDI transactions
| Form / Transaction | Used for |
|---|
| CMS-1500 | Professional / physician (outpatient) claims |
| UB-04 (CMS-1450) | Institutional / hospital facility claims |
| Clearinghouse | Scrubs and routes claims to payers electronically |
| 837 | Claim submission |
| 835 | Remittance advice (ERA) |
| 270 / 271 | Eligibility inquiry / response |
| 276 / 277 | Claim status inquiry / response |
| 278 | Prior authorization / referral |
Payers & insurance
| Payer | Covers |
|---|
| Medicare A / B | Inpatient / Outpatient & physician services |
| Medicare C / D | Advantage (managed care) / Prescription drugs |
| Medicaid | Lower-income individuals — jointly run by state and federal government |
| Commercial | Private insurers (BCBS, UHC, Aetna, Cigna, and others) |
| Other | TRICARE, Workers' Compensation, self-pay |
| COB | Coordination of benefits — the primary plan pays first, then the secondary |
Patient financial responsibility
| Term | What it means |
|---|
| Copay | A fixed amount owed per visit or service |
| Deductible | The amount a patient pays before the plan starts paying |
| Coinsurance | The patient's percentage share after the deductible is met |
| OOP maximum | The yearly cap on a patient's out-of-pocket cost |
| Premium | The monthly cost to keep coverage active |
Rejections vs. denials
| Term | What it means |
|---|
| Rejection | The claim never entered the payer's system (a front-end/format error) — fix it and resubmit |
| Denial | The claim was processed but not paid — research it, then correct or appeal |
| CARC / RARC | Codes on the remittance advice that explain why a claim was adjusted or denied |
Common denial reasons
- Eligibility or coverage inactive at the time of service
- Missing or invalid prior authorization
- Lack of medical necessity — the diagnosis doesn't support the service billed
- Coding errors, bundling issues, or NCCI edit conflicts
- Missing or incorrect information on the claim
- Duplicate claim submission
- Timely filing deadline missed
Appeals & timely filing
- Timely filing is the window to submit a claim — it varies by payer (Medicare, for example, allows one year from the date of service).
- An appeal formally challenges a denial with corrected information or supporting documentation.
- Appeal levels typically escalate: redetermination → reconsideration → a higher-level review.
- Track deadlines closely — a missed filing window usually means the claim is lost for good.
Key RCM metrics (KPIs)
| Metric | What it measures |
|---|
| Days in A/R | Average days to collect (target: roughly 40–50 or fewer) |
| Clean claim rate | % of claims accepted the first time (target: 95%+) |
| First-pass rate | % of claims paid on the first submission |
| Denial rate | % of claims denied (target: under roughly 5–10%) |
| Net collection rate | Amount collected vs. amount collectible, after adjustments |
| Cost to collect | Expense incurred per dollar collected |
| A/R > 90 days | Aged receivables — lower is better |
A/R aging is typically tracked in buckets: 0–30 → 31–60 → 61–90 → 90+ days. The older a balance gets, the harder it is to collect.
Money terms glossary
| Term | What it means |
|---|
| Allowed amount | The maximum the payer will pay for a service |
| Contractual adjustment | The write-off of the difference between the billed and contracted rate |
| Write-off | An amount removed as uncollectible or adjusted |
| EOB / ERA | Explanation of Benefits / Electronic Remittance Advice |
| EFT | Electronic Funds Transfer (payment) |
| Fee-for-service | Payment made per service rendered |
| Capitation | A fixed payment per patient, per period, regardless of services rendered |
Compliance & integrity
| Term | What it means |
|---|
| HIPAA | Protects patient PHI (minimum necessary standard) |
| Medical necessity | The diagnosis must justify the service billed |
| NCCI edits | Prevent improper unbundling of code pairs |
| Upcoding | Billing higher than what's documented — fraud |
| Fraud vs. abuse | Intentional deception vs. improper billing that isn't intentional |
RCM best practices
- Verify eligibility and authorization up front — this stops most denials before they start.
- Collect copays and estimates at the point of service.
- Code accurately and scrub claims before submission.
- Work denials fast, before the timely-filing window runs out.
- Monitor KPIs and A/R aging weekly.
- Keep documentation clear and complete — it supports every step downstream.
- Work the oldest and highest-dollar accounts first. DNFB (Discharged, Not Final Billed) is a key backlog metric to watch.
