How to read your insurance Explanation of Benefits (EOB)

Understand what your insurance paid and what you owe.

Step-by-step

1. Step 1: Find the date of service and provider

   The EOB lists each claim by date of service. Match each EOB line to a visit you actually had. If you see a claim for a service you don't recognize, call your insurer immediately — it may be fraud or a billing error.

2. Step 2: Read the billed amount vs allowed amount

   Billed Amount is what the provider sent the insurer. Allowed Amount is what the insurer agreed to pay under your network contract. The difference (write-off) is the in-network discount you negotiated by being insured.

3. Step 3: Identify your responsibility (copay, coinsurance, deductible)

   The EOB shows what the insurer paid and what you owe. Your responsibility breaks into: Deductible (the amount you pay before insurance kicks in), Copay (a fixed dollar amount per visit), and Coinsurance (a percentage of the allowed amount).

4. Step 4: Cross-reference with the provider's bill

   The provider bills you for the patient responsibility shown on the EOB. The two numbers should match. If the provider bills you more than the EOB shows, push back — providers cannot 'balance bill' you above the allowed amount in most cases.

5. Step 5: Track toward your out-of-pocket maximum

   Every dollar of copay, coinsurance, and deductible counts toward your out-of-pocket maximum. Once you hit it, the insurer pays 100% of in-network costs for the rest of the year. Your EOB shows year-to-date totals.
