How to Read a Summary of Benefits and Coverage
What each row of the standardized SBC means, how the coverage examples work, and how to compare two plans with it.
Every health plan describes itself with a marketing brochure and a legal contract. The Summary of Benefits and Coverage is the document in between. It is short, it is standardized by federal rule, and every plan has to fill out the same form. That makes it the one document where you can compare two plans line by line without decoding two different layouts.
This guide walks through the form row by row.
What the SBC is and who has to give you one
Under the Affordable Care Act, insurance companies and job-based health plans must provide two things: a plain-language Summary of Benefits and Coverage (SBC) and a Uniform Glossary of insurance terms. This applies to individual plans and job-based plans, including grandfathered plans.
You get the SBC at the moments that matter: when you shop for a plan, when you apply, when you renew, and any time you ask for it. On HealthCare.gov, each plan page links to its SBC when you preview plans and prices.
If you have a job-based plan and cannot find the SBC, use this with HR or the plan:
“I’d like a copy of the Summary of Benefits and Coverage for my plan, and for any other plan option I’m eligible for. Can you email those to me?”
You do not need a reason. The plan is required to provide it.
The top rows: the big cost questions
The first page is a table of questions and answers. These rows do most of the work:
| Row | What it actually tells you |
|---|---|
| What is the overall deductible? | What you pay before the plan starts sharing costs. Watch for separate individual and family amounts. |
| Are there services covered before you meet your deductible? | Often yes: preventive services, sometimes office visits or generic drugs. This row changes the math on how the deductible feels in practice. |
| Are there other deductibles for specific services? | Some plans run a separate prescription drug deductible. This is easy to miss and shows up here. |
| What is the out-of-pocket limit for this plan? | The most you pay in a year for covered, in-network care. Premiums do not count toward it. |
| What is not included in the out-of-pocket limit? | Usually premiums, balance bills, and non-covered services. Read this row. It is where surprises live. |
| Will you pay less if you use a network provider? | Points you to the network name. Costs in the rest of the document usually assume in-network care. |
| Do you need a referral to see a specialist? | Tells you whether the plan gates specialist visits behind a referral requirement. |
If the words in these rows are unfamiliar, the plan also owes you the Uniform Glossary, and our glossary covers the same terms. For how the deductible, copay, and coinsurance rows interact, see deductible, copay, and coinsurance.
The services table
The middle pages list common medical events: office visits, tests, drugs, outpatient surgery, emergency care, hospital stays, pregnancy, mental health, rehabilitation. For each one you get three columns: what you pay in network, what you pay out of network, and a limitations column.
Two reading habits pay off here:
- Read the in-network and out-of-network columns as different plans. A $30 copay in network can sit next to 50 percent coinsurance out of network. The gap is the real cost of leaving the network. Background: in-network vs out-of-network.
- Treat the “Limitations, Exceptions, and Other Important Information” column as the main text, not a footnote. Prior authorization requirements, visit limits, and separate facility fees live in that column.
The coverage examples
The back of the SBC contains coverage examples. The current template uses three standardized scenarios: having a baby, managing type 2 diabetes for a year, and a simple fracture treated in an emergency room. The plan simulates claims for a fixed basket of services in each scenario and shows what the patient would pay in deductibles, copays, and coinsurance.
What the examples are: a stress test of the plan’s cost sharing, run on identical inputs across every plan. That makes them the fastest way to feel the difference between two designs.
What the examples are not: a quote. The scenarios use standardized prices set for the form, not your providers’ prices, and they are not a prediction of your year. Use them to compare plans, not to budget. For budgeting, start with what things actually cost and the out-of-pocket estimator.
A worked comparison
Say you are choosing between two job-based options:
| Row | Plan A | Plan B |
|---|---|---|
| Monthly premium (from HR, not the SBC) | $120 | $310 |
| Deductible | $3,500 | $750 |
| Out-of-pocket limit | $7,000 | $4,000 |
| Primary care visit | 20% after deductible | $25 copay |
| “Having a baby” example total | $6,700 | $3,200 |
Run the year both ways. A light year: Plan A costs $1,440 in premiums plus a few visits paid at full price under the deductible. A heavy year: Plan A can reach $7,000 out of pocket plus $1,440 in premiums, about $8,440 total, while Plan B tops out at $4,000 plus $3,720 in premiums, about $7,720 total. The SBC gives you every number in that math except the premium, which comes from your enrollment materials.
Note what the coverage example did in that table. You did not have to imagine a hospital stay. The form simulated one for you, identically, on both plans.
What the SBC will not tell you
The SBC is a summary by design. It will not show the provider directory, the drug formulary, or the plan’s prior authorization list in full. It also will not resolve a billing dispute; for that you want the plan documents and your EOB. Start with how to read your EOB when a claim has already been processed.
Keep every SBC you receive. When a plan changes its terms mid-year or at renewal, the old SBC is your record of what was promised when you enrolled, and it is useful evidence if you later appeal a denied claim.
