What Does My Health Insurance Actually Cover?

Last updated July 28, 2026

Your health insurance covers exactly what your plan documents say it covers - nothing more, nothing less. Four documents hold the full answer: the Summary of Benefits and Coverage (SBC), the plan contract (often called the Evidence of Coverage, or EOC), the drug formulary, and the provider directory. Here's how to read them in minutes, and how to verify coverage before every appointment.

The honest answer: your plan is a contract

A health plan is a written contract between you (or your employer) and an insurer. It spells out every category of care the plan pays for, every condition attached, and every exclusion. And almost nobody reads it.

That gap costs people in both directions. Some pay out of pocket for care their plan already covers. Others skip benefits they're already paying for - therapy visits, physical therapy, preventive care - because they assume the answer is no (or are too afraid to risk it).

The plan knows exactly what it covers. The fix is not reading the whole contract cover to cover. It's knowing which document answers which question, and checking the handful of parts that apply to you.

Which documents answer which questions?

Four documents, four jobs:

Document	What it is	Use it to
Summary of Benefits and Coverage (SBC)	A short, standardized summary every plan must provide - same format for every plan	Get fast answers: deductible, out-of-pocket max, what common care costs you
Plan contract (often called the Evidence of Coverage or certificate of coverage)	The full legal document that governs your plan	Settles any specific question - this is the final word
Drug formulary	The list of prescription drugs your plan covers, sorted into tiers - pricing groups that set your share	Check any prescription before you fill it
Provider directory	The list of doctors and facilities in your network - providers your plan has negotiated prices with	Find in-network care, then verify by phone

All four typically live in your insurer's member portal. Can't find one? Call the member-services number on the back of your insurance card and ask for each by name, or ask your employer's benefits contact. The SBC isn't optional - every plan must provide one.

And because SBCs are standardized, they're built for side-by-side reading. That's the backbone of comparing plans during open enrollment.

How do I read my SBC in 10 minutes?

Open your SBC. Six checks, in order:

Find your deductible - what you pay for covered care before the plan starts sharing costs. Note every version: individual and family, in-network and out. (New to these terms? Here's the plain-English breakdown)
Find your out-of-pocket maximum - your worst-case annual total for covered in-network care, and the most consequential number on the page. (New to these terms? Here's the plain-English breakdown)
Check "services covered before you meet your deductible." That's care the plan shares costs on from day one - preventive care typically appears here, and sometimes office visits do too.
Scan the common-medical-events table for the rows you actually use: primary care, specialists, mental health visits, therapy, tests, drug tiers, urgent care, the ER.
Read the excluded-services box. It's short and blunt, and it prevents expensive assumptions.
Note the tripwires: referral requirements, prior authorization - the plan's advance approval for certain care - and your network's exact name - often printed on your member ID card - which you'll need to search the directory.

That's it. Ten minutes, and you know your plan better than most people ever know theirs.

What benefits do people not know they have?

You're paying for these whether you use them or not. Plans differ, so treat this as a verification checklist, not a promise that your plan includes all of it:

Preventive care at no cost. ACA-compliant plans cover a defined list of preventive services at no cost to you when you stay in-network - categories like screenings, immunizations, and annual wellness visits. One catch: the same visit can be billed as preventive or diagnostic depending on why it happens, so ask how it will be billed when you book.
Mental-health coverage. Federal parity law says a plan's mental-health and substance-use benefits can't be more restrictive than its comparable medical benefits. Check the mental-health rows of your SBC the same way you'd check any specialist visit.
Telehealth. Many plans cover virtual visits, sometimes at a lower cost than the same visit in person. Look for a telehealth line on the SBC or a telehealth option in your portal.
Physical, occupational, and speech therapy. Often covered with a visit limit per year. The limit - and whether prior authorization is required - is in the plan contract; search the PDF for "therapy."
Durable medical equipment - longer-use medical gear like crutches, braces, or home equipment. Often covered, usually with rules about approved suppliers and advance approval.
A nurse advice line. Many plans include a 24/7 line staffed by nurses at no extra cost; the number is often printed right on your insurance card.
Plan extras. Gym reimbursements, wellness credits, discount programs - these vary widely from plan to plan. Check the benefits or rewards page in your portal; if your plan has them, they're already yours.

How do I verify coverage before I get care?

The coverage question should be answered before the appointment, not after the bill arrives. One call to your insurer does it:

Call member services - the number on the back of your card.
Have the details ready: your member ID, the provider's full name and location, and what the visit is for. If the provider's office can tell you which billing codes they expect to use, read those to your insurer - codes turn "probably covered" into a real answer.
Ask the four questions, then write down the date, the rep's name, and the reference number:

"I want to verify coverage before an appointment. Is this service covered under my plan? Is prior authorization required? Is this provider in-network for my specific plan? And can I get a reference number for this call?"

The reference number is the point of the call. If the claim is later processed differently from what you were told, that record is your evidence - and the first exhibit in an appeal.

Coverage and network are different questions - check both

"Covered" answers whether your plan pays for a type of care. "In-network" answers whether the plan has a negotiated price with this particular provider. You need a yes to both, every time, because a covered service from an out-of-network provider can still produce a painful bill.

For anything at a hospital or surgery center, check the facility and the people separately. The building can be in-network while someone treating you inside it isn't. Directories go stale, so confirm twice: search the directory using your network's exact name, then ask the provider's office, "Are you in-network with my specific plan?" - and name the plan, not just the insurer. If possible, have the provider send you confirmation in writing.

NOTE: Emergencies and certain surprise out-of-network bills play by different rules - that's the No Surprises Act, explained.

One more layer: after care happens, your insurer produces an explanation of benefits showing exactly how the claim was processed. Reading it takes five minutes once you know the lines - here's the walkthrough. Know what you have. Verify before. Audit after.

The fastest free way to do all of this

Everything in this guide you can do yourself - that's why we wrote it down. Candid does the hard work of reading all these healthcare documents, for free. You upload your plan documents and it decodes the SBC and the fine print into plain English so you know what's covered, what's excluded, where the referral and prior-auth tripwires are, etc. And when a bill arrives, it checks the charges against what your plan says you owe.

Candid is our tool - this guide is complete without it. It just turns an afternoon of fine print into a few minutes.

FAQ

Is the SBC the same as my insurance policy?

No. The SBC is the standardized summary - a few pages, same layout for every plan. The plan contract (often called the Evidence of Coverage) is the governing document, and it wins if the two ever seem to disagree. Use the SBC for speed and the contract for anything high-stakes.

Does "covered" mean free?

Usually not. Covered means the plan shares the cost under its rules - deductible, copay, coinsurance. The big exception is ACA-required preventive care, which is covered at no cost when you stay in-network and the visit is billed as preventive.

How do I check if a specific treatment or procedure is covered?

Search the plan contract for the service by name, then call member services to confirm coverage, prior authorization, and network status - remember to get a reference number. If the provider can tell you the expected billing codes in advance, read them to the insurer for a firmer answer.

What if my insurer says something isn't covered but my documents say it is?

Ask the insurer to point to the exact contract language behind the decision. If the answer doesn't hold up against your Evidence of Coverage, you can challenge it - plans have a formal review process. Here's how to appeal a denied claim.

Where do I find my plan documents?

Your insurer's member portal has the SBC, the plan contract, and the formulary; the provider directory is usually a search tool on the same site. No portal access? Call the number on your card or ask your employer's benefits contact - the SBC is a document every plan must give you.
