Core RCM KPIs: Clean-Claim Rate, Days in A/R, Denial Rate, Net Collection Rate

Core Revenue Cycle KPIs#

These metrics quantify the health of a revenue cycle and are the levers an AI/automation strategy is measured against.

Clean-Claim Rate (First-Pass Yield). The percentage of claims that are accepted and adjudicated correctly on the first submission, without edits, rejections, or denials. A high clean-claim rate means fewer reworks and faster cash. Claim scrubbing and front-end edits drive this number up.

Denial Rate. The percentage of submitted claims that are denied by payers. Lower is better. Tracking denial rate *by reason* (CARC) reveals systemic problems — e.g., a spike in CARC 197 points to a prior-authorization process failure.

Days in Accounts Receivable (A/R). The average number of days it takes to collect payment after a service is billed. Lower days in A/R means faster cash conversion. Aging A/R (especially the 90+ day bucket) signals collection problems and timely-filing risk.

Net Collection Rate. The percentage of *collectible* revenue actually collected — payments divided by (charges minus contractual adjustments). It measures how well the organization captures what it is contractually owed, isolating performance from contractual write-offs (CO-45).

Cost to Collect. The total cost of running the revenue cycle as a percentage of collections. Automation aims to lower cost to collect while holding or improving collection performance.

First-Pass Resolution / Denial-Overturn Rate. How often denials are resolved on the first appeal attempt, and what share of appealed dollars is recovered.

Why these matter for AI strategy. Each KPI maps to an automation opportunity: clean-claim rate → claim scrubbing; denial rate → front-end eligibility/auth automation and denial classification; days in A/R → automated status checks (276/277) and worklist prioritization; net collection rate → underpayment detection from the 835. A credible RCM AI initiative ties every model or automation to one of these measurable outcomes.
