How to file a medical insurance claim
When and how to file a medical claim yourself — what documents to collect, where to send them, and how to track the status.
In-network providers file claims for you. You only need to file a claim yourself when you've seen an out-of-network provider, paid out of pocket, or used an international clinic. The process is straightforward, but timelines matter — most plans give you 90–180 days to submit.
What you'll need
- Itemized bill from the provider (must include CPT/HCPCS procedure codes and ICD-10 diagnosis codes).
- Proof of payment (receipt or credit card statement).
- Your insurance ID number and group number.
- The plan's claim form (download from the member portal).
- Any referrals or prior authorizations that applied to the visit.
Step-by-step
- Get a fully itemized bill
A standard receipt isn't enough. Ask the provider for a 'superbill' or itemized statement showing the procedure codes (CPT) and the diagnosis codes (ICD-10). Without these, the claim can't be processed.
- Download the claim form
Log in to your insurer's member portal and look for 'Submit a claim.' Many insurers also accept the standard CMS-1500 form.
- Fill out the form
Include patient information, member ID, dates of service, provider details, total amount paid, and a brief description of the service. Sign where required.
- Attach supporting documents
Attach the itemized bill, proof of payment, and any required referrals or authorization letters.
- Submit through the right channel
Most insurers accept claims through the member portal upload, by mail to a claims address on the back of your card, or by fax. Portal upload is fastest.
- Track the status
You should see the claim appear in your portal within 2–5 business days. Processing typically takes 15–30 days. You'll receive an Explanation of Benefits (EOB) when it's complete.
FAQ
- Do I need to file a claim for in-network care?
No. In-network providers are contractually required to file claims on your behalf. You just pay your copay or coinsurance at the visit.
- How do I file a claim for care received abroad?
International claims need extra documentation: a translated itemized bill, currency conversion, and sometimes a notarized statement. Contact the insurer's customer service before you submit.
- What happens after I file?
The plan processes the claim, applies your deductible and coinsurance, and either reimburses you (if you already paid) or pays the provider directly. You'll get an EOB explaining the math.
