What is it called when insurance denies a claim?

When an insurance company refuses to pay a claim, it is generally called a claim denial, and if the refusal is unjust or unreasonable, it is known as bad faith insurance.

Common Terms

• Claim Denial / Rejection: The formal decision by an insurer not to provide coverage or payout for a specific submitted claim.
• Bad Faith: When an insurer refuses to pay a valid claim without a reasonable basis, delays payment unnecessarily, or fails to investigate properly.
• Coverage Dispute: A general disagreement between the policyholder and the insurer regarding whether or how a policy applies to a specific loss.

What You Can Do

• Request a written explanation of the denial from your insurer.
• Review your policy documents to check for specific exclusions or definitions.
• File an internal appeal through the insurance company's formal appeal process.
• File a complaint with your state's regulatory agency, such as the California Department of Insurance if you reside in California.

Medical claim denials generally fall into three primary categories: technical (administrative) denials, clinical (medical necessity) denials, and coverage (eligibility) denials.

🗒 Overview of Denial Types

• ✅ Technical / Administrative Denials
  • Caused by clerical errors or missing data.
  • Fix: Correct the info and resubmit.
  • Examples: Missing demographics, invalid codes, or filing delays.
• ⚠️ Clinical / Medical Necessity Denials
  • Rejected because the payer deems care unneeded.
  • Fix: Submit clinical notes for appeal.
  • Examples: Diagnosis-procedure mismatch or wrong care level.
• 💡 Coverage / Eligibility Denials
  • Triggered when insurance does not apply.
  • Fix: Verify primary payer or bill patient.
  • Examples: Inactive policies or out-of-network care.

When an insurance company denies a claim, you are typically responsible for paying the bill out-of-pocket unless you successfully fight the decision. The insurer will send a formal explanation (such as an Explanation of Benefits or a denial letter) detailing why coverage was rejected.

Common Reasons for Denial

• Administrative or coding errors: Missing information, typos, or wrong medical codes.
• Lack of documentation or evidence: Insufficient proof of damage, medical necessity, or a missing police report.
• Policy exclusions or lapsed coverage: The specific service or incident isn't covered, or your policy lapsed due to missed payments.
• Missed deadlines: Submitting the claim past the allowed timeframe.

What You Can Do Next

• Review the denial letter: Read the specific rationale and note any deadlines for filing an appeal. You can learn more about managing medical denials via GoodRx.
• Gather evidence: Collect missing paperwork, medical notes, photos, or repair estimates.
• File an internal appeal: Ask the insurance company to conduct a formal review of its decision. For health plans, check details on HealthCare.gov.
• Request an external review: If the internal appeal fails, an independent third party can evaluate the case.
• Contact state regulators: File a complaint with your state's insurance commissioner if you suspect bad faith.

When an insurance claim is denied, it means the insurance company refuses to pay for the medical care, property damage, or service you submitted.

You are responsible for paying the full cost of the bill unless you successfully appeal the decision or correct an error. A denial is different from a bill you owe because you have not met your deductible yet.

Common Reasons for Denial

• Not covered: The specific treatment, service, or type of damage is excluded under your policy terms.
• Not medically necessary: For health insurance, the insurer decides the care does not meet their clinical standards.
• Administrative errors: Mistakes in billing codes, missing lab results, or late paperwork can trigger a denial.
• Lack of authorization: You or your provider failed to get a required prior authorization before receiving the service.

What You Can Do Next

• Read the denial letter: Find the specific reason why the insurance company rejected the claim.
• Fix simple errors: Contact your doctor's office or insurance agent if the denial is due to a coding or paperwork mistake.
• File an appeal: You have a legal right to challenge the decision by submitting supporting documents and a formal appeal letter. You can learn more about managing this process through resources like Patient Advocate Foundation.

The most common reason for insurance and medical claim denial is missing or inaccurate claim data—such as administrative errors, missing authorizations, or incomplete information.

Top Reasons for Claim Denials

• Missing or Inaccurate Data: Simple mistakes like misspelled names, wrong birth dates, missing policy numbers, or incorrect diagnosis and procedure codes.
• Lack of Prior Authorization: Failing to get approval from the insurance company before receiving a medical service or treatment.
• Errors in Coding: Using outdated code books or mismatching CPT (Current Procedural Terminology) and ICD-10 codes.
• Timely Filing Violations: Submitting the paperwork after the insurance company’s strict deadline (often within 90 to 180 days).
• Out-of-Network Providers: Receiving care from a doctor or facility not covered under your specific insurance plan.
