What Is a Health Insurance Claim?
Health Insurance Claim — also called Health insurance claim
A health insurance claim is a request for payment that a healthcare provider or patient submits to a health insurance company after medical services are provided. The claim includes information about the care you received so your insurer can determine whether the services are covered, how much it will pay, and what portion of the cost, if any, you may owe. Most health insurance claims are submitted electronically by healthcare providers.

What is a health insurance claim?
A health insurance claim is the process used to request payment for covered healthcare services.
After you receive medical care, your doctor, hospital, pharmacy, or other healthcare provider typically sends a claim to your insurance company.
The claim contains information such as:
- Your health insurance policy information.
- The services you received.
- Medical diagnosis codes.
- Procedure codes.
- Dates of service.
- Charges submitted by the provider.
Your insurance company reviews the claim to determine how it will be processed under your health plan.
Who submits a health insurance claim?
In most cases, your healthcare provider submits the claim on your behalf.
This is known as an assigned claim, meaning the provider bills your insurance company directly.
In some situations, you may need to submit your own claim, including when:
- You receive care from an out-of-network provider.
- Your provider does not bill your insurance company.
- Your plan requires reimbursement requests for certain services.
- You receive care while traveling.
Each insurance company has its own claim submission requirements.
What happens after a claim is submitted?
After receiving the claim, your insurance company reviews it to determine:
- Whether you were covered on the date of service.
- Whether the provider participated in your network.
- Whether the service is covered under your plan.
- Whether prior authorization was required.
- Whether the service meets medical necessity requirements.
- How much the insurer will pay.
- Whether you owe any deductible, copayment, or coinsurance.
Once the review is complete, the insurer processes the claim and issues payment according to your plan's benefits.
What information is included on a claim?
Health insurance claims generally include:
- Patient information
- Insurance identification numbers
- Healthcare provider information
- Diagnosis codes (ICD)
- Procedure codes (CPT or HCPCS, when applicable)
- Dates of service
- Charges for each service
- Supporting documentation when required
Healthcare providers use standardized coding systems so insurers can process claims consistently.
Why might a health insurance claim be denied?
Claims may be denied for many reasons, including:
- The service is not covered under the health plan.
- Prior authorization was required but not obtained.
- Required documentation is missing.
- Billing or coding errors occurred.
- The claim was submitted after the filing deadline.
- The service was determined not to be medically necessary.
- The patient was not eligible for coverage on the date of service.
A denied claim does not always mean the decision is final. Many denials can be corrected or appealed.
Health insurance claim vs. Explanation of Benefits (EOB)
These terms describe different parts of the payment process.
Health insurance claim
A request for payment submitted to the insurance company.
Explanation of Benefits (EOB)
A statement explaining how the insurance company processed the claim after its review.
The claim comes first.
The EOB explains the outcome.
Health insurance claim vs. medical bill
People often confuse these documents.
Health insurance claim
Sent to the insurance company to request payment.
Medical bill
Sent to the patient if money remains owed after insurance processes the claim.
You may receive an Explanation of Benefits before receiving a medical bill.
Common misconceptions
Myth: If my doctor submits a health insurance claim, my insurance company will automatically pay the full bill.
Reality: Submitting a claim does not guarantee payment. The insurance company reviews each claim according to your health plan's coverage, eligibility, medical necessity requirements, prior authorization rules, and cost-sharing provisions.
Why this matters
Every doctor visit, hospital stay, prescription, laboratory test, or medical procedure depends on accurate claims processing. Understanding how health insurance claims work can help you identify billing errors, understand Explanation of Benefits statements, respond to claim denials, and avoid unexpected medical expenses.
In real life
- After a primary care appointment, the physician's office submits an electronic claim to the patient's health insurance company for payment.
- A patient receives an Explanation of Benefits showing that part of the claim applied toward their deductible and that the remaining balance will be billed by the provider.
- An insurance company denies a claim because prior authorization was required for an outpatient procedure. The provider submits additional documentation during the appeals process.
