# Spot a Surprise Medical Bill with AI

AI can help you compare an unexpected medical bill with your claim and prepare questions about possible surprise billing. Connect a supported health plan through Flexpa and provide the bill. A mismatch alone does not establish a No Surprises Act violation; use CMS resources to check which protections apply.

How it works: Choose a source -> Authorize access -> Available records -> Check protections. Suggested review workflow. Connect a supported source, authorize access, and check the returned records before acting on an AI summary.

## What the No Surprises Act covers

For employer and individual health coverage, the No Surprises Act protects against many out-of-network emergency bills, certain non-emergency bills at in-network facilities, and out-of-network air ambulance bills. Exceptions apply. Medicare and Medicaid have separate billing protections.

Uninsured people and people paying without insurance generally have a right to a good faith estimate when services are scheduled at least three business days ahead or when they request one. Check the CMS guidance for the conditions and dispute process.

## How your assistant helps

- Find the claim for the visit and read how your plan processed it.
- Compare the bill's balance with your share on the claim.
- Draft questions for the provider and your plan, with the claim details attached.
- Use the CMS No Surprises resources to check protections and how to file a complaint.

## Confirm which protections apply

An AI comparison is not a legal determination. Ask your plan and provider to explain the bill. If you believe surprise-billing protections were violated, use the CMS complaint resources rather than treating the billing office as the final authority.

## What you can ask

- Was this ER visit processed as in-network?
- This bill is higher than my claim says I owe. Why might that be?
- Draft questions for the hospital billing office about this bill

## Questions

**Can AI tell if I got a surprise medical bill?** AI can help compare your bill with available claims connected through Flexpa and identify questions to ask. A difference in amounts does not by itself establish unlawful surprise billing. Check the applicable protections with CMS.

**What is the No Surprises Act?** The No Surprises Act provides federal protections against many out-of-network emergency bills, certain non-emergency bills at in-network facilities, and air ambulance bills for people with employer or individual coverage. Exceptions apply; Medicare and Medicaid have separate billing protections.

**What should I do about a possible surprise bill?** Ask your provider and health plan to explain the bill using your EOB and payment records. If you believe surprise-billing protections were violated, consult the CMS No Surprises complaint resources. An AI summary does not determine your legal rights.
