What Is a Health Insurance Claim?

health insurance claim is a request for your insurer to cover medical expenses. There are two main types:

  1. Provider-Filed Claims (most common) – Your doctor/hospital submits the claim directly.

  2. Self-Filed Claims – You submit receipts for reimbursement (common for out-of-network care).

Fun Fact: Many claims are processed automatically, but mistakes happen—so it’s smart to double-check!


Step 1: Know What Your Plan Covers (Before Treatment)

Why? Avoid surprise bills! Check:
✅ Is the provider in-network? (Out-of-network = higher costs)
✅ Does your plan cover this service? (Some exclude chiropractic, fertility, etc.)
✅ Do you need pre-authorization? (Required for surgeries, MRIs, etc.)

Pro Tip: Call your insurer or check your policy documents before treatment.


Step 2: Get an Itemized Bill from Your Provider

After treatment, request an itemized bill that lists:

  • Each service provided (CPT codes)

  • Costs for each service

  • Dates of service

Why? Errors like duplicate charges or wrong codes can lead to claim denials.


Step 3: Submit the Claim Correctly

If Your Provider Files the Claim:

  1. Confirm they’ve submitted it (ask for a copy).

  2. Check your Explanation of Benefits (EOB) for updates.

If You File the Claim Yourself:

  1. Download your insurer’s claim form (usually on their website).

  2. Attach the itemized bill and receipts.

  3. Submit via mail, email, or online portal.

Deadline Alert: Most insurers require claims within 90 days–1 year of service.


Step 4: Track Your Claim’s Status

Don’t assume it’s processed! Follow up by:
📞 Calling your insurer’s customer service
💻 Checking your online account
📧 Reviewing your EOB (Explains what’s covered/denied)

Typical Processing Time: 15–45 days.


Step 5: Review the EOB for Errors

Your Explanation of Benefits (EOB) shows:
✔ What the insurer paid
✔ What you owe (copay/deductible)
✔ Denied charges (if any)

Found an error? Dispute it ASAP with your insurer!


Step 6: Pay Your Share (If Applicable)

If the claim is approved:
💰 Pay any remaining balance (copay/coinsurance).
📩 Keep records of payments for tax/tracking purposes.


What If Your Claim Is Denied?

Don’t panic! Follow these steps:

1. Find Out Why It Was Denied

Common reasons:

  • Out-of-network provider

  • Missing pre-authorization

  • Coding errors

2. Appeal the Decision

  • Write a formal appeal letter (include supporting documents).

  • Submit within deadlines (usually 180 days).

3. Escalate If Needed

If the appeal fails, contact:

  • Your state’s Department of Insurance

  • health insurance lawyer (for major disputes)
