What Is Claim Scrubbing?
Claim scrubbing is the automated pre-submission process that runs claims through a rule-set of payer-specific and standards-based edits (NCCI, MUE, HIPAA syntax, payer policies) to identify and correct errors before the claim leaves the practice.
- Maintain a continuously updated edit library and review denial and rejection reason codes monthly, but sort that list into two buckets before building anything.
- Some recurring reasons map cleanly onto a pre-submission edit: a missing or invalid modifier, a code pair that keeps hitting the same NCCI edit, units over a published MUE.
- Those need a named owner, a standing work queue and an appeal path rather than another edit.
- Treating every recurring denial as an edit-shaped problem is how an edit library grows noisy without moving the rate.
Claim Scrubbing
Also known as: Claim Editing; Pre-submission Edits; Front-end Edits
Claim scrubbing is the automated pre-submission process that runs claims through a rule-set of payer-specific and standards-based edits (NCCI, MUE, HIPAA syntax, payer policies) to identify and correct errors before the claim leaves the practice.
Definition
Performed by the practice management system, the EHR, or the clearinghouse, claim scrubbing applies a layered set of edits: HIPAA syntax (loop/segment validity, required data elements), code validity (current-year CPT/ICD-10), NCCI PTP edits, MUE limits, payer-specific edits (e.g., Medicare LCD ICD-10 lists), modifier appropriateness, and place-of-service consistency. Claims that fail edits are queued for correction; claims that pass are transmitted to the payer. What a scrubber can test is bounded by what is machine-readable on the claim — structure, code validity and stated relationships. It can check whether a required modifier is present and permitted, whether a code pair hits a CMS procedure-to-procedure edit and which modifier indicator that edit carries, and whether the units billed exceed a published medically unlikely edit. It cannot read the clinical note, so it cannot decide whether the documentation supports the code selected, whether the service was medically necessary, or how a payer will apply its own coverage, benefit and authorization rules. Those are the decisions that survive a clean scrub and come back as denials. Scrubbing does lift First-Pass Resolution Rate, but the 95% figure usually quoted beside it is an operating target a practice sets for itself, not a measured benchmark: no free primary source publishes an observed first-pass distribution for physician practices.
Example
A claim for CPT 99213 with modifier 25 paired with CPT 11102 (a tangential biopsy of skin, single lesion) on the same date. The scrubber can confirm that modifier 25 is present and valid on the E/M line, screen the code pair against NCCI procedure-to-procedure edits and read the modifier indicator where an edit applies, confirm that each ICD-10-CM code is valid and pointed at a service line, and apply whatever payer-specific modifier-25 edit has been loaded into the rule set. What it cannot check is the thing the modifier actually asserts — that the E/M was significant and separately identifiable from the procedure. That judgment lives in the documentation, and it is what an auditor or a post-payment reviewer will read.
Common Misconceptions
Clearinghouse scrubbing is not a substitute for in-system scrubbing — clearinghouse edits typically run last and miss many payer-specific rules. A common arrangement is a primary scrub in the PM/EHR, a secondary scrub in the clearinghouse, and a charge-edit dashboard to catch repeat patterns.
Practical Application
Maintain a continuously updated edit library and review denial and rejection reason codes monthly, but sort that list into two buckets before building anything. Some recurring reasons map cleanly onto a pre-submission edit: a missing or invalid modifier, a code pair that keeps hitting the same NCCI edit, units over a published MUE. Others cannot be edited away, because they are decided only after the claim reaches adjudication — medical necessity and coverage determinations, benefit limits, coordination of benefits, and payer documentation requirements. Those need a named owner, a standing work queue and an appeal path rather than another edit. Treating every recurring denial as an edit-shaped problem is how an edit library grows noisy without moving the rate.

Clean Claim
A clean claim is a properly completed claim that requires no additional information from the provider or a third party and no special handling, so the payer can accept it into adjudication without manual intervention. Clean means accepted for processing — not paid.
Read definitionNCCI (National Correct Coding Initiative)
NCCI is a CMS-published set of edits that prevent improper payment when incorrect code combinations or unit counts are submitted. The program contains three edit types: Procedure-to-Procedure (PTP) edits, Medically Unlikely Edits (MUE) limiting units of service, and Add-on Code edits.
Read definitionMUE (Medically Unlikely Edits)
MUEs are CMS-published per-line, per-beneficiary, per-day unit limits for HCPCS/CPT codes that flag claim lines exceeding the maximum number of units typically performed for a given service.
Read definitionFirst-Pass Resolution Rate
First-Pass Resolution Rate is the percentage of claims paid on first submission — no rejection, no denial, no corrected claim and no appeal — measured against every claim submitted in the period. Its complement is rejections plus denials, not denials alone.
