Out of Pocket Maximum in Health Insurance
A health insurance plan can look affordable until a big medical bill arrives. The monthly premium is easy to compare, but the number that tells you the most about worst-case costs is often the out-of-pocket maximum.
This one limit can protect you from an endless pileup of deductibles, copays, and coinsurance. It also helps you compare plans in a more practical way. A low premium may look good, but a high out-of-pocket maximum can still leave you exposed if you need surgery, ongoing treatment, or expensive prescriptions.
This guide explains what an out-of-pocket maximum means, what counts toward it, what does not count, and how to use it when choosing a health plan. It also includes internal and external links so you can keep learning from trusted sources.

What an out-of-pocket maximum means
An out-of-pocket maximum is the most you should have to pay in a plan year for covered, in-network health care services that count under your plan.
Once your eligible spending reaches that limit, your health insurance plan generally pays 100% of covered in-network costs for the rest of the plan year.
That sounds simple, but the details matter. The limit usually applies only to:
Covered services
In-network providers
Costs that your plan says count toward the limit
The current plan year
If you get care outside your network, receive a service your plan does not cover, or continue paying monthly premiums, those costs may not reduce your out-of-pocket maximum.
A common search phrase is “Out of pocket maxmium,” but the correct term is out-of-pocket maximum. You may also see it called an OOP max, out-of-pocket limit, or maximum out-of-pocket cost.
For a broader overview of plan cost terms, see our internal guide to health insurance basics. For a federal explanation, HealthCare.gov also has a helpful page on out-of-pocket maximums and health insurance costs.
How the out-of-pocket maximum works during the year
Health insurance costs usually build in stages. The out-of-pocket maximum sits at the top of those stages.
Here is the typical order:
You pay premiums to keep coverage active.
You pay for covered care until you meet your deductible.
After the deductible, you may pay copays or coinsurance.
Those eligible payments add up toward your out-of-pocket maximum.
Once you hit the maximum, the plan pays covered in-network care at 100% for the rest of the plan year.
The out-of-pocket maximum resets when the new plan year begins.
A simple example
Say a plan has:
Plan feature | Example amount |
Annual deductible | $2,000 |
Coinsurance after deductible | 20% |
Out-of-pocket maximum | $7,500 |
Now imagine you have a covered in-network surgery. The allowed amount is $30,000.
You might pay:
Step | What happens | Your cost |
Deductible | You pay the first $2,000 | $2,000 |
Coinsurance | You pay 20% of the next covered amount | $5,500 |
Out-of-pocket maximum reached | Your eligible spending hits $7,500 | $0 more for covered in-network care that year |
In this example, even though 20% coinsurance on the remaining bill could have been higher, your out-of-pocket maximum stops your eligible cost at $7,500.
The plan then pays the rest of the covered in-network costs for the year, as long as the services are covered and you follow the plan rules.
Out-of-pocket maximum versus deductible
The deductible and out-of-pocket maximum often get confused because both describe what you pay. They are different numbers with different jobs.
A deductible is the amount you pay for many covered services before your plan starts sharing costs.
An out-of-pocket maximum is the most you pay for covered in-network services during the plan year before the plan pays 100% of eligible costs.
Here is the cleanest way to think about it:
Cost term | What it means | What happens after you reach it |
Premium | Monthly amount to keep insurance active | Coverage stays active as long as you keep paying |
Deductible | Amount you pay before the plan pays for many services | The plan starts paying part of eligible costs |
Copay | Fixed amount for a service or prescription | You keep paying copays until rules change or you hit the OOP max |
Coinsurance | Percentage you pay after the deductible | You keep paying your share until you hit the OOP max |
Out-of-pocket maximum | Highest eligible in-network cost for the plan year | The plan pays 100% of covered in-network care |
A deductible can be much lower than the out-of-pocket maximum. That means meeting your deductible does not always mean your medical care becomes free. You may still owe copays or coinsurance until you reach the out-of-pocket maximum.
For more on deductibles, see our internal explainer on how health insurance deductibles work.
What usually counts toward the out-of-pocket maximum
Plans vary, but many ACA-compliant health insurance plans count these costs when they are for covered in-network care:
Deductible payments
Copays for covered visits
Coinsurance for covered services
Covered prescription drug costs
In-network emergency care cost sharing
Cost sharing for covered lab work, imaging, therapy, and hospital care
The Affordable Care Act requires most non-grandfathered health plans to apply an annual limit on cost sharing for essential health benefits. This is one reason the out-of-pocket maximum matters so much for marketplace and many employer plans. The federal limit can change by year, so it is best to confirm current limits through HealthCare.gov or your insurer.
Preventive care may cost $0 before you reach the maximum
Many plans cover certain preventive services without cost sharing when you use an in-network provider. That means you may not pay anything for those services, even if you have not met your deductible.
Examples can include certain screenings, vaccines, and annual preventive visits, depending on your age, plan, and health needs. HealthCare.gov lists covered preventive health services for many marketplace plans.
Because preventive care often has no cost, it may not add anything to your out-of-pocket maximum. That is usually a good thing. You are getting covered care without paying toward the limit.
What usually does not count toward the out-of-pocket maximum
This is where many surprises happen. The out-of-pocket maximum does not include every dollar related to health care.
These costs often do not count toward your out-of-pocket maximum:
Monthly premiums
Your premium keeps your coverage active. It does not usually count toward your deductible or out-of-pocket maximum.
If your plan costs $450 a month, that is $5,400 a year in premiums. Even if your out-of-pocket maximum is $7,500, your total annual spending could be higher because premiums sit outside that limit.
Out-of-network care
Many plans have separate rules for out-of-network care. Some plans have no out-of-network coverage except emergency care. Others have a separate, higher out-of-network out-of-pocket maximum.
If your plan does not count out-of-network bills toward your in-network maximum, those costs can add up fast. With some plans, out-of-network providers can also bill more than the insurer’s allowed amount.
The federal No Surprises Act offers protections against certain unexpected out-of-network bills, such as some emergency bills and certain services at in-network facilities. The rules are specific, so review information from the Centers for Medicare & Medicaid Services on surprise medical billing protections.
Non-covered services
If your plan does not cover a service, your payment for that service usually does not count toward the out-of-pocket maximum.
Examples might include:
Cosmetic procedures that are not medically necessary
Certain fertility services, depending on the plan
Experimental treatments not covered by the policy
Care that requires prior authorization but was not approved
Services excluded in the plan documents
Plan rules matter. Always check the Summary of Benefits and Coverage, often called the SBC, before getting expensive care when possible.
Costs above the allowed amount
Insurers often use an allowed amount, which is the price they recognize for a covered service. If a provider charges more than the allowed amount, your plan may not count the extra amount, especially with out-of-network care.
For example, if an out-of-network provider charges $1,200 and your insurer’s allowed amount is $800, your plan may base cost sharing only on $800. The remaining $400 could become your responsibility and may not count toward your maximum.
Penalties for not following plan rules
Some plans require referrals, prior authorization, or specific provider networks. If the plan reduces or denies payment because you skipped a required step, the extra cost may not count toward the out-of-pocket maximum.
For more on provider networks, see our guide to HMO, PPO, EPO, and POS plans.
Individual and family out-of-pocket maximums
Family coverage can include two kinds of out-of-pocket maximums:
An individual out-of-pocket maximum for each covered person
A family out-of-pocket maximum for everyone on the plan combined
Many family plans use an embedded individual maximum. This means one family member does not have to meet the full family maximum alone before the plan starts paying 100% for that person’s covered in-network care.
Example of an embedded family maximum
Say a family plan has:
Limit | Amount |
Individual out-of-pocket maximum | $6,000 |
Family out-of-pocket maximum | $12,000 |
One child has a year with many covered medical needs and reaches $6,000 in eligible in-network costs. The plan then pays 100% of that child’s covered in-network care for the rest of the year.
The rest of the family may still have cost sharing until the family’s combined eligible spending reaches $12,000. Once the family maximum is met, the plan pays 100% of covered in-network care for everyone on the plan for the rest of the year.
This detail is especially important for families that expect one person to have higher medical costs than everyone else.
Why the out-of-pocket maximum matters when comparing plans
Many people compare health plans by monthly premium first. That makes sense because premiums affect the budget every month. But premiums alone can be misleading.
The out-of-pocket maximum shows your possible exposure if you need a lot of care.
A low-premium plan may have:
A higher deductible
Higher coinsurance
A higher out-of-pocket maximum
A narrower provider network
A higher-premium plan may have:
A lower deductible
Lower copays
A lower out-of-pocket maximum
Better coverage for expected prescriptions or visits
Neither type is always better. The better plan is the one that fits your health needs, risk tolerance, budget, and preferred providers.
Compare total possible annual cost
A practical way to compare plans is to estimate two numbers.
The first is your best-case annual cost. This is mostly premiums, plus any predictable low-cost care.
The second is your worst-case covered in-network cost. This is annual premiums plus the out-of-pocket maximum.
Here is a simple comparison:
Plan | Monthly premium | Annual premiums | Out-of-pocket maximum | Worst-case covered in-network cost |
Plan A | $300 | $3,600 | $9,000 | $12,600 |
Plan B | $450 | $5,400 | $5,500 | $10,900 |
Plan A costs less each month. But if you have a major medical year, Plan B could cost less overall because its out-of-pocket maximum is lower.
This does not mean Plan B is always the better choice. You also need to compare networks, prescriptions, covered services, referral rules, and whether your doctors participate.
Estimate your likely use of care
If you expect very little care, a lower-premium plan may make sense. If you expect surgery, childbirth, ongoing specialist care, expensive medication, or regular therapy, the out-of-pocket maximum becomes more important.
Common reasons to look closely at the out-of-pocket maximum include:
A planned procedure
A known chronic condition
Pregnancy or fertility treatment
A child with recurring medical needs
High-cost prescriptions
Regular mental health care
Frequent specialist visits
A physically risky job or hobby
The out-of-pocket maximum does not predict what will happen. It gives you a ceiling for eligible covered costs, which helps you plan for risk.
Marketplace, employer, Medicare, and Medicaid plans can work differently
The basic idea of an out-of-pocket maximum is common, but the rules can differ by coverage type.
Marketplace plans
Health plans sold through the health insurance marketplace must follow rules for annual cost-sharing limits on covered essential health benefits. These plans are grouped into metal tiers, such as Bronze, Silver, Gold, and Platinum.
Bronze plans often have lower premiums and higher out-of-pocket costs. Gold and Platinum plans often have higher premiums and lower out-of-pocket costs. Silver plans can be especially important for people who qualify for cost-sharing reductions.
You can learn more at HealthCare.gov, the federal marketplace site used by many states.
Employer-sponsored plans
Employer plans usually list the out-of-pocket maximum in the Summary of Benefits and Coverage. Employers may offer several choices, such as a high-deductible health plan paired with a Health Savings Account, or a PPO with higher premiums and lower point-of-care costs.
If you have employer coverage, check:
Whether the plan has separate in-network and out-of-network maximums
Whether prescriptions share the same maximum as medical care
Whether the plan has an embedded individual maximum for family coverage
Whether your expected doctors, hospitals, and medications are covered
Human resources or the benefits administrator can usually provide plan documents, but the insurer is often the best source for claim-specific questions.
High-deductible health plans and HSAs
Some high-deductible health plans, often called HDHPs, can be paired with a Health Savings Account, or HSA. These plans must meet federal rules for deductibles and out-of-pocket limits.
An HSA lets eligible people save pre-tax money for qualified medical expenses. These rules can change, so confirm current details with the IRS page on Health Savings Accounts and other tax-favored health plans.
An HDHP may work well for people who want lower premiums and can set aside money for potential costs. It can be risky for someone who cannot comfortably handle the deductible or out-of-pocket maximum.
Medicare
Original Medicare does not work exactly like many private health plans. Original Medicare generally does not have the same kind of annual out-of-pocket maximum for Part A and Part B services. Many people add Medigap coverage or choose Medicare Advantage to help manage cost exposure.
Medicare Advantage plans do have annual out-of-pocket maximums for covered Part A and Part B services, but rules, networks, and prescription coverage can vary.
For official information, visit Medicare.gov.
Medicaid and CHIP
Medicaid and the Children’s Health Insurance Program, known as CHIP, have different cost-sharing rules that vary by state and eligibility category. Many people with Medicaid have low or no out-of-pocket costs, but details depend on the program.
For a starting point, visit the federal Medicaid site at Medicaid.gov.
Prescription drugs and the out-of-pocket maximum
Prescription drug costs can be one of the trickiest parts of out-of-pocket maximums.
Some plans combine medical and prescription spending under one out-of-pocket maximum. Others may have separate drug deductibles or tiers that affect what you pay before the maximum is reached.
Prescription costs may count when:
The drug is covered by the plan
You use an in-network pharmacy
The medication is on the plan formulary
You follow any prior authorization or step therapy rules
Your payment is considered eligible cost sharing
Costs may not count when:
The drug is not covered
You choose a non-covered brand drug when a covered alternative exists
You use a coupon that changes what the plan counts
You buy from an out-of-network pharmacy
You pay outside insurance instead of running the claim through the plan
Drug manufacturer coupons can be especially confusing. In some plans, the coupon amount may not count toward your deductible or out-of-pocket maximum. Your own payment might count, but the assistance amount might not. Rules vary by plan and by state.
Before filling an expensive prescription, ask the insurer or pharmacy:
Is this drug covered?
What tier is it on?
Does it require prior authorization?
Does it count toward my deductible?
Does it count toward my out-of-pocket maximum?
Is there a lower-cost covered alternative?
For a deeper explanation of medication tiers, see our internal guide to prescription drug formularies.
Common mistakes that can raise your costs
A plan’s out-of-pocket maximum is useful only when you understand the rules that control it. These mistakes can make costs higher than expected.
Assuming premiums count
Premiums almost never count toward the out-of-pocket maximum. When planning a yearly budget, add premiums separately.
A plan with a $6,000 out-of-pocket maximum and $500 monthly premium can still cost up to $12,000 for the year when you include premiums, assuming you reach the maximum.
Using out-of-network care by accident
Before a planned service, confirm that the facility, doctor, lab, anesthesiologist, imaging center, and pharmacy are in network. It is possible for a hospital to be in network while certain professionals who work there are not.
Surprise billing protections may help in some situations, but it is still wise to check network status before planned care.
Forgetting the plan year reset
Out-of-pocket maximums reset at the start of each plan year. If your plan year begins January 1, your eligible spending usually resets then.
If you have control over timing, and your doctor agrees, it may help to schedule follow-up care, imaging, or procedures after you have already met your maximum. Medical timing should always come first, but cost timing can matter when care is flexible.
Ignoring prior authorization
Some services require insurer approval before care. If you skip that step, the plan may deny the claim or cover less.
Prior authorization is common for:
Some surgeries
Advanced imaging
Certain medications
Durable medical equipment
Inpatient stays
Some specialty care
Before expensive care, ask the provider and insurer whether authorization is required and whether approval has been received.
Looking only at the deductible
A low deductible can still come with high coinsurance and a high out-of-pocket maximum. A high deductible plan may look scary but could have a manageable maximum, especially if paired with employer HSA contributions.
Compare the whole cost structure, not one number.
How to find your out-of-pocket maximum
You can usually find the out-of-pocket maximum in several places.
Summary of Benefits and Coverage
The Summary of Benefits and Coverage is the easiest place to start. Look for a line that says something like:
`What is the out-of-pocket limit for this plan?`
This section should also list what is not included in the limit, such as premiums, balance billing, or health care this plan does not cover.
Insurance card and member portal
Your insurance card may list basic copays, but it may not show the full out-of-pocket maximum. The member portal usually has more detail, including:
Deductible progress
Out-of-pocket maximum progress
Recent claims
Prescription spending
Explanation of Benefits documents
Explanation of Benefits
An Explanation of Benefits, often called an EOB, is not a bill. It shows how the insurer processed a claim.
Look for:
Amount billed
Plan discount
Allowed amount
Amount paid by the plan
Amount you may owe
Amount applied to deductible
Amount applied to out-of-pocket maximum
If something looks wrong, call the insurer before paying the provider bill.
Plan documents
The full plan document or Evidence of Coverage gives more detail than the summary. This is where you will find deeper rules about networks, referrals, exclusions, prescription drugs, and appeals.
Questions to ask before choosing a plan
When comparing plans, use the out-of-pocket maximum as part of a full checklist.
Ask these questions:
What is the in-network out-of-pocket maximum?
Is there an out-of-network out-of-pocket maximum?
Do prescription drug costs count toward the same limit?
Is there a separate drug deductible?
Are my doctors and hospitals in network?
Are my medications covered?
What are the copays for primary care, specialists, urgent care, and emergency care?
What coinsurance applies after the deductible?
Does the family plan have embedded individual limits?
Are referrals or prior authorizations required?
What costs do not count toward the maximum?
If you are comparing marketplace plans, check subsidies and cost-sharing reductions before deciding. A Silver plan with cost-sharing reductions may have much lower out-of-pocket costs for eligible applicants.
How to budget around the out-of-pocket maximum
The out-of-pocket maximum is a planning number. It tells you how much eligible in-network care could cost in a bad medical year, before premiums.
Here are practical ways to budget around it.
Add premiums and the maximum together
To understand your worst-case covered in-network exposure, add:
`Annual premiums + out-of-pocket maximum`
This gives a more realistic ceiling than either number alone.
Build a medical emergency fund if possible
If your plan has a $7,000 out-of-pocket maximum, try to build savings toward that number over time. Even partial savings can reduce stress when bills arrive.
If you have an HSA-eligible plan, an HSA can help set aside pre-tax money for qualified medical expenses. If you have an FSA through work, it may also help, though FSAs usually have use-it-or-lose-it rules.
Track claims during the year
Do not rely only on provider bills. Track claims in your insurer portal. Provider bills and insurer records can move at different speeds.
Keep a simple record of:
Date of service
Provider
Amount billed
Amount insurer allowed
Amount you paid
Amount applied to deductible
Amount applied to out-of-pocket maximum
This helps catch errors and confirms when you are close to meeting the limit.
Ask for estimates before planned care
For planned procedures, request a cost estimate from both the provider and insurer. Ask for procedure codes if needed. An estimate is not a guarantee, but it can help you understand likely costs.
Also ask whether every part of the service is in network, including labs, imaging, anesthesia, and facility fees.
The bottom line on out-of-pocket maximums
The out-of-pocket maximum is one of the most important numbers in a health insurance plan. It shows how much you may have to pay for covered in-network care in a plan year before the insurer pays 100% of eligible costs.
But it is not a cap on everything. Premiums, out-of-network care, non-covered services, balance billing in some cases, and rule-related penalties may sit outside the limit.
When comparing plans, look beyond the monthly premium. Add annual premiums to the out-of-pocket maximum, check the network, review prescription coverage, and read the Summary of Benefits and Coverage. That gives you a clearer view of what a plan could really cost in both an ordinary year and a difficult one.
A good next step is simple: find the out-of-pocket maximum on your current plan, then check what counts toward it. That one number can make your health insurance choices much easier to understand.
