Responsibility for a medical billing error depends on where the mistake occurred. The healthcare practice generally remains responsible for ensuring that claims submitted under its billing credentials are accurate and compliant, even when billing is outsourced. However, the specific error may originate with a provider, coder, biller, front-office employee, or billing company.
Does the Healthcare Provider Remain Responsible for Billing Errors?
Yes. For Medicare and Medicaid claims, providers have an important responsibility to ensure claims are accurate and supported by documentation. OIG states that providers are responsible for claims submitted under their number, while CMS also places billing and payer-information responsibilities on providers.
This does not mean every mistake was personally made by the physician. The practice should have appropriate Compliance, Medical Coding, Claim Scrubbing, and billing controls to identify and correct errors.
Can a Medical Billing Company Be Responsible for an Error?
A billing company can contribute to an error when its work causes inaccurate claims, such as incorrect CPT or ICD-10 coding, improper claim submission, or missed billing information. OIG guidance recognizes that third-party billing companies can discover provider mistakes and have their own compliance responsibilities.
The contract between the practice and billing company can also determine how operational responsibilities and financial consequences are handled.
Who Usually Causes Medical Billing Errors?
The source of an error can vary:
- Provider: Incomplete or inaccurate clinical documentation
- Coder: Incorrect CPT, ICD-10, modifier, or coding interpretation
- Biller: Claim-entry or submission errors
- Front office: Incorrect demographics or insurance information
- Authorization staff: Missing or incorrect Prior Authorization
- Billing company: Errors in outsourced billing, coding, claims, Payment Posting, or A/R Management
For example, if a cardiology practice documents a procedure correctly but the wrong CPT code is submitted, the coding or billing workflow may be the source of the error rather than the physician’s clinical documentation.
What Should a Practice Do When It Finds a Billing Error?
The practice should identify the cause, stop or correct affected claims where appropriate, review whether an overpayment occurred, and determine whether a corrected claim, refund, appeal, or other action is required. OIG recommends auditing and taking corrective action when billing problems are identified.
A medical billing audit can help identify recurring coding, documentation, claim, and workflow problems before they become larger compliance or revenue-cycle issues.
How Can Practices Prevent Medical Billing Errors?
A practical control system should include Eligibility Verification, accurate documentation, Credentialing checks, authorization review, Medical Coding oversight, Claim Scrubbing, timely claim submission, Payment Posting controls, and regular A/R review.
The Medicator’s provides medical billing and RCM services that can support these processes and help practices identify recurring billing problems.
If your practice is seeing repeated Claim Denials or billing discrepancies, reviewing the workflow that created the error is often more useful than correcting each claim individually. A structured billing audit can help pinpoint where the problem begins and what controls should be improved.
