Claim scrubbing
The automated process of reviewing and validating claims for errors, missing data, and rule violations before they are submitted to payers. Claim scrubbing software checks for demographic completeness, valid CPT and ICD-10 code combinations, NCCI bundling edits, modifier requirements, and payer-specific rules. Claims that fail the scrubber are returned to the billing team for correction before submission.
Why this matters for your clinic
Claim scrubbing is the quality gate between your billing workflow and the payer's adjudication system. A rejection at the payer level costs you the same rework time as a denial, and in some cases more, because rejected claims do not always generate an ERA response. A scrubber that catches the same errors before submission saves the rework and keeps AR days lower.
Scrubbers are not perfect. They enforce rules programmatically but cannot check whether the documentation actually supports the code submitted, whether medical necessity criteria are met, or whether the clinical information in the claim is consistent with the encounter. A claim can pass the scrubber and still be denied for medical necessity or documentation reasons. Scrubbing reduces technical errors; it does not eliminate clinical review denials.
Payer-specific scrubbing rules are the most important and the most often overlooked. Most practice management systems include generic NCCI edit checking but do not capture the proprietary bundling and medical necessity rules that individual commercial payers apply. A clearinghouse with payer-specific rules loaded into its scrubber provides a material improvement over generic scrubbing alone.
What good looks like
HFMA MAP Keys treat clean claim rate (post-scrubbing) at or above 98% (HFMA MAP Keys high-performer target; 95% is the broader healthy band) as the target. AAPC and HFMA both recommend clearinghouse-level scrubbing with payer-specific edits as a best practice. CMS publishes the NCCI edit tables, which are the authoritative source for Medicare-specific bundling edit rules that scrubbers use.
Example
A practice submits 1,800 claims per month. Before implementing payer-specific claim scrubbing, 12% of claims are rejected or denied on the first pass, requiring rework. After implementing a clearinghouse with commercial payer-specific rules loaded, the rejection/denial rate on first pass drops to 6%. At an estimated $30 rework cost per claim, the 108-claim monthly reduction in rework saves $3,240 per month in billing staff time and accelerates cash flow on those claims.
From Sorso
Scrubber quality varies significantly between clearinghouses. In the RCM reviews we do, the clearinghouse with the most comprehensive payer-specific rules loaded consistently outperforms the generic alternatives on first-pass resolution rate for the same billing team.
