Billing teams should catch errors before a claim reaches the payer to reduce the risk of denial. Claim scrubbing is one way to catch those errors before submission. During this pre-check claim scrubbing process, the billing team reviews patient information, insurance details, coding, modifiers, claim formatting, and payer-specific rules.
These denials stem from simple clerical oversight while entering patient information, to more technical NCCI bundling errors. Each denial forces the practice to correct the claim and submit it again. The billing team spends more time on follow-up. The practice also waits longer for payment. Practices now deal with more first-submission denials from Medicare, Medicaid, and commercial payers. A thorough claim-scrubbing process reduces avoidable back and forth rework.
What Is Claim Scrubbing in Medical Billing?
A claim scrubber runs the 837P or 837I claim file through data, coding, and payer-specific edits. Claim scrubbing in medical billing is a quality control process to identify errors in claims prior to submitting to an insurance company or clearinghouse for processing. This can cause a claim to reject or deny before it enters payer adjudication. It flags missing or invalid patient information, subscriber details, provider identifiers, CPT or HCPCS codes, ICD-10-CM codes, diagnosis pointers, modifiers, place-of-service codes, units of service, duplicate lines, and required payer fields. It also checks code combinations against NCCI procedure-to-procedure edits and reviews units against medically unlikely edit thresholds.
The billing team resolves each failed edit, corrects the source data or coding issue, and releases the claim only after it passes the applicable checks. The aim is to maximize the First Pass Acceptance Rate (FPAR) of medical billing claims.
Why Claim Scrubbing Matters More Than Ever
As Medicare/Medicaid & commercial payers implement more sophisticated auto-denial Algorithms, practice claim scrubbing is becoming the primary line of defence .According to the data, the average claim denial rate is 11.8% (OS Healthcare, 2026) and 86% of these denials are the result of fixable claim errors. The Healthcare Financial Management Association (HFMA) estimates that it costs between $25 to $118 to rework and appeal a single denied claim.
The HFMA and MGMA estimate that 60% of denied claims are never re-submitted and billions of dollars are lost annually to the healthcare industry. The solution to recover these lost billions is claim scrubbing prior to claim submission. The industry standard is that 95% of claims should be error free on the first submission and practices are encouraged to scrub claims prior to submission to reach this standard. All this data is a testament to the importance of Claim Scrubbing in Revenue Cycle Management.
How the Claim Scrubbing Process Works
Claim scrubbing in medical billing follows a clear sequence that begins the moment a patient is seen and ends only when a verified and error-free claim reaches the payer. Here is how each step works:
Step 1 — Charge Capture: Claim Scrubbing starts with converting clinical documentation into a billable financial claim. This step is critical as any errors caused here will be carried forward into the subsequent steps. Any clerical oversight at this step, will trigger a ripple effect.
Step 2 — Medical Coding: In this step, CPT Codes are assigned to the procedure rendered, ICD codes are used for the disease diagnosed and HCPCS Codes are used for equipment and supplies. If necessary, modifiers are also appended. Errors at this step will be carried forward into the adjudication of the claim
Step 3 — Claim Creation: The billing system generates a claim, typically in the 837 electronic format. The system structures the claim with patient and charge information. An initial version of the claim is created at this system step.
Step 4 — Pre-Submission Scrubbing: This claim scrubber step examines the claim against payer requirements, demographic data and a multitude of coding requirements. It ensures that all required claim fields are filled, no duplicate service lines are present and ensures the rules are followed. Payer line scrubbing, demographic data scrubbing and required field completion are also performed. In established workflows, step 4 also includes eligibility verification to confirm active coverage prior to submission.
Step 5 — Payer-Specific Rule Checks: The processing rules for multiple payers, including Medicare, Medicaid, commercial payers, workers’ compensation carriers and managed care plans can be poles apart. This is true even when dealing with the same service. Some payers will mandate the use of modifiers, while others may require prior authorization or appropriate use of place-of-service codes. The scrubber uses the payer-specific logic to highlight these variances before the claims are submitted.
Step 6 — NCCI Edit and Bundling Review: National Correct Coding Initiative (NCCI) edits are checks for code pairs that are not to be billed together in most circumstances as established by CMS. If an NCCI edit is found, the claim will be checked. Documentation will support billing for the service with the claim and modifier 59, XE, XS, XP, or XU will be added. The modifier will not be added without the supporting documentation and clinical justification as it creates a compliance risk.
Step 7 — Error Correction and Release: All claims that are flagged are submitted for a biller-review. The team resolves the issue and verifies the documentation (when applicable) and resubmits the claim to the clearing house or the payer. Only claims that have passed all of the aforementioned steps are submitted in this final stage.
Common Errors Caught During Claim Scrubbing
Claim scrubbing helps avoid human induced errors and streamline the claim submission and payment processing. While some denials involve complex concepts of medical necessity, the majority claims stem from administrative oversight.
Coding Errors
Errors in coding stem from invalid or out of date CPT/ICD-10 codes, missing or incorrect modifiers, absence of medical necessity or may/ may not be up or down coded. Scrubbing identifies coding errors where the documentation is inconsistent with the level of service billed.
Patient Information Errors
Errors in patient demographics, misspelled names, incorrect or missing date of birth, incorrect and/or outdated insurance, incorrect insurance policy numbers are all errors that will cause immediate claim rejections. Claim scrubbing is critical for correct data entry.
Authorization and Eligibility Issues
Claim denials occur due to missing prior authorization, services that are out of plan or are not covered and services that are out of the patient care service date or provider network. Scrubbing systems are designed to identify these errors before submission.
Duplicate and Incomplete Claims
Claims that are duplicated due to unnecessary resubmission and/or lack phrased requirements (such as NPI, Referring Provider, etc.) can be denied due to scrubbing oversight.

Who Should Use Claim Scrubbing?
Claim scrubbing should be used by all healthcare organizations that submit claims. These organizations include practicing physicians, specialty clinics, urgent care, hospitals, outpatient or ambulatory surgery centers, therapy practices, behavioral health groups, diagnostic centers and medical-dental billing teams. The complexity and diversity of what a healthcare organization does and the type of payers they work with makes scrubbing more critical. Scrubbing claims should be used by practice managers to improve and maintain cash inflow and decrease the workload on the billing team.
Key Benefits of Claim Scrubbing for Your Practice
One of the biggest benefits your practice will derive from scrubbing claims will be fewer denials. Claims that are submitted to payers in an error-free manner will be processed in an accelerated manner. Compliance will improve too, since scrubbing will prevent billing errors. Incorporating NCCI edits, coding and payer policy scrubbing will make improper billing much less likely.
| Metric | Without Strong Scrubbing | With Strong Scrubbing |
| Clean claim rate | Lower and inconsistent | Higher and more predictable |
| Denial volume | More preventable denials | Fewer avoidable denials |
| Payer Processing Turnaround | Claims delayed by 14–21 days | Claims auto-adjudicated in under 14 days |
| Cash flow | Slower reimbursement | Faster payment cycles |
| Compliance risk | High exposure to NCCI violations and audit flags | Real-time pre-submission control and rules |
How to Choose Claim Scrubbing Software
Your software selection for claim scrubbing should be data-driven and address your firm’s unique challenges. Instead of going straight to the feature sheets; consider your trends in denial history and your payer mix and calculate your first-pass acceptance rate. The ideal system for your practice will not only have a range of features but will plug your specific revenue leaks.
At a minimum, high-performance scrubbing software must have Real-time NCCI edits, CPT/ICD-10 validation and automated modifier logic. It must also have built-in prior-authorization alerts, eligibility verification and duplicates detection.

Claim Scrubber vs. Denial Management Software: What’s the Difference?
A claim scrubber prevents problems before claims are submitted. Denial management software helps manage problems after claims are denied. Both are useful, but they solve different parts of the revenue cycle. Practices need both but prevention should come first. A denial management system can help recover revenue but it cannot recover the time already lost.
Claim Scrubbing vs. Clearinghouse Edits vs. Claim Adjudication
In revenue cycle management, a claim is subjected to three entirely different separate layers of validation before reimbursement is issued. Claim scrubbing is the first of these three layers, followed by Clearinghouse edits and finally there is claim adjudication which is payer’s internal evaluation process. Understanding the significance of each is equally crucial to the success of the billing process.
| Feature | Claim Scrubbing | Clearinghouse Edits | Claim Adjudication |
| Where It Happens | Within the practice’s internal software (PMS/EHR). | At a neutral third-party platform (e.g., Availity). | Inside the insurance payer’s private portal or system. |
| When It Occurs | Before the claim leaves the provider’s domain. | After leaving the provider, but before reaching the payer. | After the payer formally receives the claim transmission. |
| Primary Focus | Deep coding compliance, clinical logic, and medical necessity. | Structural file formatting, basic loop errors, and clean routing. | Contractual coverage rules, benefit limits, and final payouts. |
| Core Benefit | Catches 86% of avoidable front-end billing and code errors. | Minimizes structural electronic transmission formatting failures. | Results in a final financial decision |
Conclusion
Claim Scrubbing in Medical Billing is an effective means of mitigating preventable denials. Claim scrubbers identify a host of claim issues that would otherwise result in payment delays. These include demographic errors, gaps in authorization, duplicate claims, incomplete data, NCCI edits and numerous payer issues. The key takeaway for all the decision makers in a healthcare setting or a medical billing company is the establishment and employment of an effective Claim Scrubbing Mechanism if they wish to accelerate reimbursement and minimize claim backlog. If an organization focuses on denial prevention during the claim submission process ultimately they will avoid spending time on post claim denial management processes.
Frequently Asked Questions
- Does claim scrubbing assure payment?
No. Guaranteeing payment is not possible with claim scrubbing because payers can still deny claims due to a lack of medical necessity, coverage limitations, insufficient documentation, or policy changes. Claim scrubbing does, however, substantially reduce errors caused by negligence prior to claim submission.
- What is the average time for claim scrubbing?
With the use of an automated system, the average time for claim scrubbing is only a few seconds to minutes. The time is highly dependent upon the volume of claims being processed and the configuration of the system. Claims that do not clear system edits are more time consuming because they are processed manually after being reviewed and corrected.
- What is an acceptable clean claim rate?
Generally, practices strive for a first pass claim rate of 95% or more. Revenue cycle management teams perform best when they monitor this metric and compare it against claim submission acceptance rate, denial rate, accounts receivable days and net collection rate.
- What is the effect of claim scrubbing on denial rates?
Denial rates are decreased considerably by claim scrubbing due to timely detection of coding errors, incomplete or incorrect information, eligibility and authorization issues, and payer-specific claim issues.
- What is the effect of claim scrubbing on telehealth claims?
Telehealth claims may rely on the correct use of claim-specific place of service codes, the use of telehealth modifiers and an understanding of payer policy rules, provider eligibility, and coverage. Claim scrubbing can identify and resolve these issues prior to claim submission.
