How to Reduce Insurance Claim Denials

Measure Your Denial Rate by CARC Code

You cannot reduce denials you have not quantified. Pull a 90-day denial report from your practice management system grouped by CARC code and payer. Rank the results by dollar volume, not claim count. A handful of CARC codes — typically 50, 97, 197, 29, and 4 — drive 60% or more of denial dollars in most practices. Fix the top three codes first before addressing long-tail denial reasons.

Build Front-End Verification Into Scheduling

Verify eligibility and benefits before the patient arrives, not after the claim is submitted. Confirm prior authorization requirements for scheduled procedures and obtain auth numbers before the date of service. Capture accurate demographics and insurance information at check-in with real-time eligibility verification through your clearinghouse. Every auth missed at scheduling costs 45 minutes of appeal work later.

Clean Claim Edits Before Submission

Run claims through your clearinghouse edit checks before transmission. Catch NCCI bundling conflicts, missing modifiers, invalid diagnosis-to-procedure pairings, and duplicate claims at scrub time — not at remittance. Practices that implement pre-submission editing reduce initial denial rates by 3 to 5 percentage points within the first quarter.

Appeal Fast on Denials You Cannot Prevent

Some denials are clinical or payer-policy driven and will happen regardless of front-end work. Build a 48-hour appeal turnaround target for denials above a dollar threshold you set — $100, $250, or $500 depending on your volume. Speed matters because appeal deadlines are fixed and staff attention fades as denial queues grow. Automating appeal letter generation removes the biggest bottleneck in your denial recovery workflow.
