What a Clearinghouse Does

  • Acts as a middleman: It sits between a medical office and health insurance companies.
  • Checks for errors: It reviews medical bills for missing data or wrong codes before sending them out. This process is called claim scrubbing.
  • Standardizes data: It translates billing files into the exact format required by each specific insurance company.
  • Speeds up payments: It helps practices get paid faster by reducing claim rejections.

Other Common Examples

  • Waystar
  • Change Healthcare
  • Office Ally

Why would a clearinghouse reject a claim?

A clearinghouse rejects a medical claim before it reaches the insurance payer because it fails basic electronic formatting, data validation, or compliance edits.

Common Reasons for Clearinghouse Rejections

  • Incorrect Patient or Subscriber Information: Typos in the patient's name, wrong date of birth, or an invalid/missing member ID number.
  • Provider Data Mismatches: Missing, invalid, or mismatched National Provider Identifier (NPI) numbers, or missing referring provider details.
  • Invalid or Outdated Coding: Using non-billable or obsolete ICD-10 diagnosis codes, CPT procedure codes, or missing required modifiers.
  • Formatting and Data Entry Errors: Missing required data fields, incorrect data formats, or an invalid Payer ID directing the claim to the wrong place.
  • Duplicate Submissions: Accidentally submitting the exact same claim twice for the same date of service.

You can review specific submission rules using the Centers for Medicare & Medicaid Services Office Ally resources or cross-check your practice management system formatting.

What is a Clearinghouse Under HIPAA?

HIPAA Compliance Requirements

  • Business Associate Status: When they perform specific functions on behalf of other providers or health plans, they may also operate with business associate obligations.
