Key Takeaways
- The Summary of Benefits and Coverage (SBC) is a standardized 8-page document every health plan must provide by federal law.
- The SBC breaks down your deductible, out-of-pocket maximum, copays, and coinsurance in a consistent, comparable format.
- Coverage examples in the SBC show real-dollar estimates for common medical scenarios, making plan comparisons concrete.
- The exclusions and limitations section reveals what the plan will not pay for — often the most overlooked section.
- You must review your SBC before open enrollment closes because plan details can change significantly from year to year.
- Comparing SBCs side by side across two or three plans is the fastest way to find the best financial fit for your situation.
What the SBC Is and Why It Exists
The Summary of Benefits and Coverage, commonly called the SBC, is a standardized document that every health insurance plan — whether offered by an employer, purchased on a marketplace, or obtained through Medicaid — must provide under the Affordable Care Act. Think of it as a federal requirement that forces insurance companies to use plain, consistent language so that you can actually compare apples to apples when you're deciding between plans.
Before the SBC existed, each insurer designed its own plan documents in its own format, which made comparisons nearly impossible. Now, every SBC follows the same eight-page template with the same section headings in the same order. That consistency is your friend during open enrollment.
If you want a full picture of how the SBC fits into the broader enrollment process, see our complete open enrollment guide which walks through every stage from choosing a plan type to confirming your coverage start date.
Your employer or insurer is legally required to provide the SBC before you enroll — not after. If you have not received it, ask your HR department or log into your insurer's portal. For marketplace plans, it is available on the plan comparison page before you click "enroll."
What You Need Before You Start
Reading an SBC in isolation only gets you so far. To make it useful, gather these items before you sit down with the document.
What you will need
Once you have everything in front of you, you are ready to work through each section of the SBC methodically. If you want a broader checklist that covers steps beyond the SBC itself, the open enrollment checklist covers verifying provider networks, confirming subsidies, and submitting your election before the deadline.
Current plan's SBC document
Provides the baseline coverage and cost details you are comparing against.
Competing plan SBC documents
Enables direct, standardized comparison of costs and benefits across plans.
Plan's drug formulary
Confirms whether your specific medications are covered and at which cost tier.
Provider directory
Verifies that your preferred doctors and hospitals are in-network under each plan.
Highlighter and notepad
Lets you mark key figures and jot notes directly on the SBC as you read.
Spreadsheet or comparison table
Organizes cost figures from multiple SBCs so you can see tradeoffs at a glance.
Step-by-Step: Reading Every Section of Your SBC
Work through these steps in order. Each one targets a specific section of the SBC document. Do not skip the later steps — the exclusions and coverage examples sections are where most people miss critical information.
Read the Plan Overview Box (Page 1, Top Section)
The very first box on page 1 tells you the plan name, the insurer, the coverage period, and the plan type — such as HMO, PPO, or HDHP. Confirm these match what HR or the marketplace told you. Errors here — even typographical ones — can cause coverage problems later.
Note whether a referral is required to see a specialist. HMOs require one; PPOs typically do not. This one detail affects how freely you can access care.
Identify Your Deductible — All Three Versions
The SBC lists three deductible figures you need to understand:
- Individual in-network deductible: The amount you personally pay before the plan starts sharing costs, when you use in-network providers.
- Family in-network deductible: The combined threshold for your household. Once any combination of family member spending hits this number, the plan pays for everyone.
- Out-of-network deductible: A separate, usually much higher threshold that applies when you see providers outside the plan's network.
Record all three numbers. If you are covering dependents, the family deductible is the number that determines your realistic worst-case out-of-pocket scenario for medical costs alone.
Find and Record the Out-of-Pocket Maximum
The out-of-pocket maximum is the most important number in your SBC. It is the most you will ever pay in a single plan year for covered in-network services. After you hit this number, the plan pays 100% of covered costs for the rest of the year.
Like the deductible, there is an individual out-of-pocket maximum and a family out-of-pocket maximum. ACA-compliant plans cap the individual out-of-pocket maximum at a federally set limit (adjusted annually — check the current year's limit on HealthCare.gov).
Important distinction: Not everything counts toward your out-of-pocket maximum. Premiums never count. Out-of-network costs typically do not count. Some plans also exclude certain costs — check whether copays and coinsurance both count, or only one of them.
Map Out Copays and Coinsurance for Services You Actually Use
Pages 2 through 4 of the SBC contain the Common Medical Events table — a grid that shows what you pay for dozens of service types. Do not read every row. Instead, focus on the rows that match your actual healthcare usage:
- Primary care office visits
- Specialist visits (especially any specialists you see regularly)
- Urgent care
- Emergency room visits
- Outpatient mental health visits (if applicable)
- Outpatient surgery (if you have a planned procedure)
- Diagnostic imaging such as MRI or CT scans
- Prescription drugs: generic, preferred brand, non-preferred brand, and specialty tiers
For each row, note whether you pay a flat copay (a fixed dollar amount, like $30) or coinsurance (a percentage of the allowed amount, like 20%). Also note whether the deductible must be met first before those rates kick in — look for the phrase "after deductible" in the cost column.
Read the Excluded Services Section Carefully
Near the end of the SBC — typically on page 7 — is a section titled Excluded Services and Other Covered Services. This is where the plan lists what it will never cover, regardless of medical necessity. Common exclusions include:
- Routine dental and vision care for adults
- Cosmetic surgery
- Long-term custodial care
- Infertility treatments (some plans cover diagnostics but not treatment)
- Weight-loss surgery (unless specific criteria are met)
- Hearing aids
- Acupuncture and chiropractic care (limits vary widely)
Highlight any exclusion that affects a service you use or anticipate needing. If something on this list surprises you, contact the insurer's member services line to confirm the exclusion applies to your specific situation before you lock in your enrollment.
Study the Coverage Examples and Translate Them Into Your Life
The SBC is required to include two standardized coverage examples: "Having a Baby (Maternity and Newborn Care)" and "Managing Type 2 Diabetes (as a Chronic Condition)." A third example, "Simple Fracture," is also commonly included.
These examples use a standardized set of assumed medical events and prices. The dollar figures shown are what a typical person in that scenario would pay under this specific plan. Because every SBC uses the same assumptions, these numbers are directly comparable across plans — making them arguably the most useful comparison tool in the entire document.
Even if you are not pregnant or diabetic, use these examples as a proxy for "what does moderate-to-heavy use of this plan cost me?" A plan that looks cheap based on premiums alone may show a significantly higher coverage-example figure than a competing plan.
Check the Glossary and Confirm You Understood Every Term You Highlighted
The last page of the SBC includes a uniform glossary of terms — or a link to one. Before you finalize your review, look up any term you highlighted or were uncertain about. The definitions in this glossary are the legal definitions as they apply to your plan.
Pay special attention to these commonly misunderstood terms:
- Allowed amount
- The maximum price the plan will use as the basis for calculating your cost-share. If a provider charges more than the allowed amount and is out-of-network, you may owe the difference (called balance billing).
- Coinsurance
- Your share of the cost of a covered service, calculated as a percentage of the allowed amount after the deductible is met.
- Copayment
- A fixed dollar amount you pay for a covered service, usually at the time of service.
- Prior authorization
- Approval from the insurer before you receive certain services or medications. Without it, the plan may deny your claim entirely.

Plan Details Can Change Year to Year
Even if you are staying on the same plan you had last year, your insurer may have changed the deductible, the out-of-pocket maximum, or the drug tier structure. Never assume last year's numbers still apply. Pull the current year's SBC and read it from scratch each open enrollment season.
Out-of-Network Costs May Not Appear Fully in the SBC
The SBC shows out-of-network cost-sharing percentages, but it cannot show you the full cost risk of going out-of-network. If a provider charges $15,000 for a procedure and the plan's allowed amount is $8,000, you may owe the full $7,000 difference through balance billing — on top of your coinsurance. Always verify network status before receiving non-emergency care.
How to Compare Two SBCs Side by Side
Once you have read your current plan's SBC, the real power comes from comparing it to one or two alternatives. Here is a quick framework:
| What to Compare | Plan A | Plan B |
|---|---|---|
| Monthly premium | $___ | $___ |
| Individual deductible | $___ | $___ |
| Out-of-pocket maximum | $___ | $___ |
| Primary care copay | $___ | $___ |
| Specialist copay | $___ | $___ |
| Generic drug cost | $___ | $___ |
| Emergency room cost | $___ | $___ |
| Coverage example: Having a Baby | $___ | $___ |
Fill in the table using each plan's SBC. A plan with a lower premium almost always has a higher deductible — the table forces you to see the tradeoff in one place.
Use the 'Worst Case' Test
For each plan you are comparing, calculate the worst-case annual cost: 12 months of premiums plus the out-of-pocket maximum. The plan with the lowest worst-case total is the safest financial choice if you expect significant medical needs. If you are generally healthy and rarely use care, compare the best-case cost: 12 months of premiums plus your average annual out-of-pocket spending.
Request SBCs in Advance of the Deadline
Open enrollment windows are typically four to six weeks long, but many people wait until the final days to review their options. Request all SBCs during the first week of the enrollment window. This gives you time to ask HR, your insurer, or a navigator follow-up questions before the deadline closes. Rushing through an SBC in the final 24 hours leads to overlooked exclusions and costly mistakes.
Save Your SBC After Enrollment
Once you have enrolled, save the SBC as a PDF and store it somewhere you can find it during the plan year. If a claim is denied, you will want to reference the SBC to verify whether the service should have been covered. Insurers are required to honor the terms disclosed in the SBC.
If your situation involves significant recurring care — ongoing prescriptions, specialist visits, or planned procedures — also check the what's covered hub to confirm those specific services appear in your chosen plan's covered benefits.
For questions specific to your employer-sponsored options, especially about benefits that do not appear on the SBC such as HSA contributions or wellness incentives, read smart questions to ask HR before enrollment closes.
Common Mistakes When Reading an SBC — and How to Avoid Them
After years of helping people through open enrollment, I see the same errors repeat. Here are the most consequential ones and what to do instead.
- Focusing only on the premium
- The monthly premium is just one cost. A plan with a $150 lower monthly premium but a $2,000 higher deductible costs you more the moment you need care. Always calculate your total potential cost: 12 months of premiums plus worst-case out-of-pocket spending.
- Skipping the exclusions section
- Page 7 of the SBC lists what the plan does not cover. Common exclusions include certain fertility treatments, weight-loss surgery, adult dental and vision care, and out-of-country emergency care. If any of those matter to you, find out before you enroll.
- Assuming in-network = available
- Just because a service is covered in-network does not mean any provider near you is in the network. The SBC will not list specific providers. Cross-check the plan's provider directory separately before committing.
- Ignoring the coverage examples
- The "Having a Baby" and "Managing Type 2 Diabetes" examples are standardized estimates. They are not exact predictions, but they are calibrated to the same assumptions across every plan, making them the fairest comparison tool you have.
- Not checking the drug formulary
- The SBC shows drug tier cost-sharing (e.g., $15 for generic, $50 for preferred brand), but it does not list specific drug names. If you take brand-name medications, look up the plan's drug formulary — a separate document — to confirm your medication is covered and at what tier.
Missing the Deadline Has Real Consequences
If you do not elect or waive coverage before the open enrollment deadline, you will typically be locked out of making changes until the next annual enrollment window — unless you experience a qualifying life event such as marriage, birth of a child, or loss of other coverage. Read the SBC now, not the day before the deadline. For information on what qualifies as a life event, see the special enrollment rules that apply to your situation.
The SBC Is a Summary — Not the Full Policy
The SBC provides a standardized overview, but it does not contain every plan rule. Before assuming a specific service or drug is covered, verify with the full plan document (called the Evidence of Coverage or Summary Plan Description) or call member services directly. For complex situations — ongoing treatments, upcoming surgeries, or specialty medications — always get written or electronic confirmation of coverage before you proceed.
If your plan type changes significantly — for example, moving from a PPO to an HDHP — and you have questions about whether that affects your eligibility for a special enrollment period in the future, the special enrollment hub explains qualifying life events that allow you to make changes outside the annual window.
For ACA marketplace enrollees, the ACA open enrollment checklist pairs well with this guide and covers subsidy verification steps specific to marketplace plans.
And if you are also evaluating dental coverage separately, note that dental plan summaries of benefits work differently from health plan SBCs. See how to read a dental plan's summary of benefits for that walkthrough.
