Every health plan you shop this Open Enrollment comes with a Summary of Benefits and Coverage, or SBC, and most people never open it. That leaves the best comparison tool in health insurance unused. Federal law requires health insurers and group health plans to give you an SBC in the same standard format, so plans from two different companies can be read side by side, line by line. This guide walks through a summary of benefits and coverage section by section and shows how to use its coverage examples to see which plan costs less for the kind of year you expect.
What a summary of benefits and coverage is (and is not)
The SBC requirement comes from the Affordable Care Act, at 42 U.S.C. § 300gg-15, with the detailed rules in 45 C.F.R. § 147.200. Together they set the shape of the document: a uniform format, plain language, no print smaller than 12-point, and no more than four double-sided pages. Most of the wording is fixed by the federal template, so one insurer's SBC reads almost exactly like another's. That sameness is the point.
Two limits to know up front. The SBC is only a summary: the full policy or plan document controls if the two disagree. And the SBC does not show the premium, so you have to add that yourself.
When you are entitled to get one
You do not have to hunt for an SBC. Under the federal rule, you should receive one:
- When you apply. An insurer must provide it within seven business days of receiving your application.
- When you renew. If your plan renews automatically, the SBC is generally due at least 30 days before the new plan year starts.
- Whenever you ask. A plan or insurer must send one within seven business days of a request, free of charge.
- Before a mid-year change. If a material change that affects the SBC takes effect outside a renewal, you must get notice at least 60 days in advance.
Page one: the Important Questions chart
The SBC opens with a chart of seven questions that always appear in the same order. Each has an Answers column, filled in by the plan, and a "Why This Matters" column whose wording is set by the template. The seven questions are:
- What is the overall deductible?
- Are there services covered before you meet your deductible?
- Are there other deductibles for specific services? (A separate prescription drug deductible shows up here.)
- What is the out-of-pocket limit for this plan?
- What is not included in the out-of-pocket limit? (Premiums, balance-billing charges, and care the plan does not cover are typical entries.)
- Will you pay less if you use a network provider?
- Do you need a referral to see a specialist?
If you read only one page, make it this one. The deductible and out-of-pocket rows set your worst-case exposure; our guide to the deductible vs. out-of-pocket maximum explains how they work together. The second row often decides the comparison: one plan may cover primary care or generic drugs before the deductible while another does not. If the plan uses a network, it must link to its provider directory here, and the template warns that a network provider might use an out-of-network provider for some services, such as lab work. See our explainer on in-network vs. out-of-network care.
Pages two and three: the Common Medical Event chart
Next comes a long chart of everyday situations: a doctor's visit, a test, a prescription, an emergency room visit, a hospital stay, mental health care, pregnancy, and recovery care. For each, the "What You Will Pay" columns show your cost sharing, usually one column for network providers and one for out-of-network. An HMO with no out-of-network benefits simply says "Not covered" in the second column.
The template's conventions are precise. Coinsurance appears as a percentage, a copayment as a per-visit or per-prescription amount, "No charge" means you pay nothing, and "Deductible does not apply" means the service skips the deductible. Otherwise, the copays and coinsurance shown apply after the deductible is met. Our copay vs. coinsurance guide has worked examples.
Do not skip the far-right column, "Limitations, Exceptions, & Other Important Information," where prior authorization rules, visit limits, and similar fine print live. The prescription row also links to the plan's drug list; if you take a regular medication, check it using our walkthrough of how a formulary works.
The sections people skip: exclusions and your rights
After the chart comes a list of excluded services and other covered services, the fastest way to spot a plan that does not cover something you care about, such as adult dental care or routine eye care. Then come standard sections on your rights to continue coverage, your grievance and appeals rights, and two yes-or-no questions: does the plan provide minimum essential coverage, and does it meet the minimum value standard? On an employer plan, a "No" on minimum value matters, because the template notes you may then be eligible for a premium tax credit through the Marketplace.
Coverage examples: the best tool for comparing two plans
The SBC ends with coverage examples, standardized scenarios that currently cover having a baby, managing type 2 diabetes, and a simple fracture. HHS supplies every insurer with the same treatment data, and each scenario's "Total Example Cost" must be left exactly as the template provides. Each plan fills in only what the patient would pay under its own deductible, copays, coinsurance, and limits. Because the starting point is identical on every SBC, that patient-pays figure is a true apples-to-apples comparison.
To compare two plans, pick the scenario closest to your expected year and add a full year of premiums to each plan's patient-pays number. A low-premium plan can cost more overall in a year with significant care. Remember that the examples are illustrations, not estimates of your costs: the figures are rounded on purpose and use self-only cost sharing even when the SBC describes family coverage. Our 7-step checklist for choosing a plan puts the SBC in a broader shopping method.
Where to find SBCs and get help comparing them
Marketplace plans usually link the SBC from the plan details, employer plans include it with enrollment materials, and any insurer must send one on request. Our Open Enrollment 2027 guide covers this season's deadlines.
If you would rather have someone walk through the SBCs with you, a licensed agent can pull them for the plans available where you live and check them against the doctors and prescriptions you use. You can request a free quote to get started. Your actual costs depend on the care you receive and your plan's terms, so confirm details against the full policy documents.
