What Is a Clean Claim?
A clean claim is one that passes through the payer's adjudication system without requiring additional information, correction, or manual review. It contains accurate patient demographics, valid insurance information, correct procedure and diagnosis codes, appropriate modifiers, and supporting documentation that matches the billed services.
The MGMA recommends a clean claim rate of 95% or higher. Practices that consistently achieve this benchmark spend significantly less on rework, experience faster payment cycles, and maintain healthier cash flow. Every percentage point below 95% represents real revenue delayed or lost. According to the Healthcare Financial Management Association (HFMA), the cost to rework a denied claim ranges from $25 for simple corrections to $118 for complex multi-level appeals.

Rendering provider NPI is correct and active
Billing provider NPI and tax ID match payer enrollment records
Referring provider NPI included when required
Provider is credentialed and in-network with the patient's plan
5 Documentation
Clinical notes support every billed service and diagnosis code
Medical necessity is clearly documented for services that require it
Notes are signed and dated by the rendering provider
Any required attachments (operative notes, pathology reports) are ready to submit
6 Final Verification
Claim is being submitted within the payer's timely filing window
No duplicate claim already submitted for the same date of service and procedure

Frequently Asked Questions
What is a clean claim rate and how do I calculate it?
Your clean claim rate is the percentage of claims that are accepted and paid on first submission without any rework. Calculate it by dividing the number of claims paid on first submission by the total number of claims submitted in the same period. For example, if you submit 500 claims in a month and 475 are paid without needing correction, your clean claim rate is 95%.
What are the most common reasons for claim rejections?
The most frequent causes are incorrect or inactive patient insurance information, coding errors (wrong CPT or ICD-10 codes, missed modifiers, unbundling violations), missing or expired prior authorizations, and provider credentialing issues. Eligibility verification alone prevents an estimated 30% of all denials.
Should I use this checklist for every single claim?
Ideally, every claim goes through a pre-submission review. For high-volume practices, focus the manual checklist on high-dollar claims, new patients, complex procedures, and any service that has historically generated denials. Use automated claim scrubbing software to handle the routine checks at scale. Our guide on claim scrubbing best practices covers how to prioritize.
