Common Reasons Health Insurance Claims Are Denied and How to Address Them

Introduction: Understanding Health Insurance Claim Denials

Health insurance is an essential part of life in the United States, helping millions of people cover their medical expenses. When you have health insurance, you expect your plan to pay for your medical bills as promised. However, sometimes when you or your healthcare provider submit a claim to your insurance company, the claim gets denied. This can be confusing and stressful, especially if you were counting on that coverage.

Why Health Insurance Claims Matter

Health insurance claims are requests sent to your insurance company asking them to pay for medical services you have received. These claims can include doctor visits, hospital stays, medications, surgeries, and more. If a claim is approved, your insurance will pay all or part of the bill according to your policy. If a claim is denied, you may have to pay out-of-pocket, which can be expensive.

What Does “Denial” Mean?

A denial means that the insurance company has refused to pay for a service or treatment. There are many reasons why this might happen. Sometimes it’s a simple paperwork mistake; other times it’s because the insurer thinks the service isn’t covered by your plan. No matter the reason, a denied claim can cause stress and financial worry for patients and their families.

The Impact of Denied Claims on Patients

Impact Description
Financial Stress Patients may face large unexpected bills they thought would be covered.
Delayed Care If payment is denied, patients might put off needed treatments or procedures.
Confusion & Frustration Navigating the appeals process or understanding why a claim was denied can be overwhelming.
Access Issues Sometimes denied claims prevent patients from getting the care they need.
The Bottom Line

Understanding how health insurance claims work—and what happens when they’re denied—is important for anyone with insurance in the U.S. Knowing why denials happen and what you can do about them can help you avoid surprises and stay on top of your healthcare costs.

2. Missing or Incorrect Information

One of the most common reasons health insurance claims get denied in the United States is missing or incorrect information on the paperwork. Even small mistakes, like a wrong policy number or a missing signature, can cause big headaches and lead to delays or outright denials of your claim.

Common Examples of Missing or Incorrect Information

Type of Error Description
Wrong Policy Number The policy number entered doesn’t match what’s on file with your insurance company.
Misspelled Names Your name, your provider’s name, or other important details are spelled incorrectly.
Missing Signatures Required signatures from you or your healthcare provider are left blank.
Lack of Documentation Necessary forms, receipts, or doctor’s notes are not included with your claim.
Incorrect Dates of Service The date you received care is entered wrong or does not match the records.

How to Fix These Errors

  • Double-Check All Paperwork: Before submitting any claim, carefully review all forms for accuracy. Make sure every field is filled out and all numbers match your insurance card and medical bills.
  • Gather Required Documents: Check if you need to attach extra documents, like itemized bills, referrals, or notes from your doctor. Missing paperwork is a frequent reason for denials.
  • Ask for Help: If you’re unsure about anything, contact your healthcare provider’s billing department or your insurance company. They can help clarify what’s needed.
  • Fix and Resubmit: If you find out after submission that something was missing or incorrect, correct the mistake and resubmit the claim as soon as possible. Many insurance companies allow claims to be corrected and refiled within a certain time frame.
  • Keep Copies: Always keep copies of everything you submit. This helps track what’s been sent and makes it easier to fix errors if they come up later.

Quick Tip:

If you get a denial letter that mentions “missing information” or “incomplete form,” check which specific parts were flagged. Address those directly when you resubmit so your claim moves forward smoothly.

Non-Covered Services or Out-of-Network Providers

3. Non-Covered Services or Out-of-Network Providers

One of the most common reasons health insurance claims are denied in the United States is when patients receive care that is either not covered by their plan or from providers who are not in the insurance network. Understanding your coverage and network rules can save you time, money, and stress.

What Are Non-Covered Services?

Non-covered services are treatments, procedures, or supplies that your health insurance plan doesn’t pay for. This could include elective cosmetic surgery, some alternative therapies like acupuncture (depending on your plan), or certain prescription drugs. Before you schedule a procedure or fill a prescription, check your plan’s list of covered services—also known as the Summary of Benefits and Coverage (SBC).

In-Network vs. Out-of-Network Providers

Insurance companies contract with specific doctors, hospitals, and clinics—these are called “in-network” providers. If you visit an out-of-network provider (one that does not have a contract with your insurer), you’ll often pay much more out of pocket, or your claim may be denied altogether.

Key Differences at a Glance

In-Network Provider Out-of-Network Provider
Coverage Level Usually higher coverage; lower costs to you Lower coverage or none; higher costs to you
Claim Denial Risk Low (if service is covered) High (many claims denied)
Billing Process Provider bills insurance directly You may need to pay upfront and file your own claim

How to Check Coverage Before Receiving Care

  • Review Your Plan Documents: Always read your SBC and provider directory before scheduling any appointments.
  • Call Your Insurance Company: Use the customer service number on your insurance card to ask about specific services or providers.
  • Ask Your Provider: Confirm they are in-network for your specific plan—not just the insurance company in general.
  • Get Pre-Authorization: For some procedures, you must get approval from your insurer before receiving care. Ask if this step is needed.
If You Receive a Denial Due to Non-Covered Service or Out-of-Network Care:
  • Contact your insurer for clarification—it may be a billing error.
  • If possible, appeal the denial following the steps listed in your policy documents.
  • If urgent care was required while traveling or in an emergency, provide documentation to support an exception request.
  • Ask about payment plans or financial assistance options if you owe a large bill.

By understanding what’s covered and sticking with in-network providers, you can avoid many claim denials and keep your healthcare costs under control.

4. Pre-Authorization and Referrals

Why Pre-Authorization and Referrals Matter

One of the most common reasons health insurance claims are denied in the U.S. is because a required pre-authorization or referral was not obtained before receiving care. Many insurance plans require you to get approval (pre-authorization) for certain procedures, tests, or medications, and sometimes you need a referral from your primary care doctor before seeing a specialist.

What Can Happen Without Them?

If you skip these steps, your claim might be denied—even if the treatment itself is covered under your plan. This can lead to surprise bills or having to pay the full cost out-of-pocket.

Typical Scenarios Requiring Pre-Authorization or Referral

Situation Is Pre-Authorization Needed? Is Referral Needed?
MRI or CT Scan Yes, usually No
Elective Surgery Yes Sometimes
Seeing a Specialist No Often, especially with HMO plans
Expensive Prescription Medications Yes, often No
Physical Therapy Sometimes Sometimes

How Policyholders Can Avoid These Denials

  • Check Your Plan Details: Before scheduling any procedure or specialist visit, review your insurance policy documents or member portal to see if pre-authorization or a referral is needed.
  • Talk to Your Doctor’s Office: Ask your provider’s office staff—they’re used to dealing with insurance and can help get the necessary approvals.
  • Contact Your Insurance Company: If you’re unsure, call the customer service number on your insurance card. Get confirmation in writing if possible.
  • Keep Documentation: Save emails, approval letters, and any reference numbers related to pre-authorizations and referrals.
  • Avoid Last-Minute Requests: Getting approvals can take several days. Don’t wait until right before your appointment or procedure.
If Your Claim Is Denied for Missing Authorization or Referral:
  • You have the right to appeal. Gather all documentation showing you followed the process—or that you were not informed a pre-authorization was needed—and submit it along with your appeal.
  • If there was a misunderstanding or emergency situation, explain this clearly in your appeal letter.
  • Your doctor’s office may also help by providing supporting documents to back up your claim.

The key takeaway: Always double-check with both your insurance provider and healthcare provider about what’s required before getting non-emergency care. This small step can save you time, money, and stress later on.

5. How to Appeal a Denied Claim

Understanding Your Rights

If your health insurance claim is denied, don’t panic. Under U.S. law, you have the right to appeal the decision. This means you can ask your insurance company to review and reconsider their decision about your claim. The Affordable Care Act (ACA) requires insurers to explain why they denied your claim and provide instructions on how to file an appeal.

Steps to Take When a Claim Is Denied

Step What To Do
1. Review the Denial Letter Read your Explanation of Benefits (EOB) or denial letter carefully. It should state the reason for denial and give details about your appeal rights.
2. Gather Documentation Collect all relevant paperwork, including medical records, doctor’s notes, bills, and previous communications with your insurer.
3. Contact Your Insurance Company If anything in the denial letter is unclear, call your insurer’s customer service line for clarification. Ask them to explain exactly why the claim was denied.
4. Request an Internal Appeal Submit a written request for an internal appeal. Follow the instructions in your denial letter and include any supporting documents or statements from your healthcare provider.
5. Consider an External Review If your internal appeal is denied, you may be eligible for an external review by an independent third party. This option is required by federal law for most health plans.

Your Appeal Rights Under U.S. Law

  • You usually have 180 days (about six months) from receiving a denial to file an appeal.
  • The insurer must provide a clear process for filing appeals and respond within set timeframes (typically 30-60 days).
  • If the situation is urgent, you may request an expedited (faster) review.
  • You can appoint someone (like a doctor or family member) to act on your behalf during the appeal process.

Tips for a Successful Appeal

  • Be organized: Keep copies of everything you send and receive.
  • Write clearly: Explain why you believe the claim should be covered and reference any policy language that supports your case.
  • Get professional help if needed: Some states offer consumer assistance programs, or you can ask your doctor’s office for support with medical documentation.
  • Follow up regularly: Check in with your insurance company to track the progress of your appeal.
