Your out-of-pocket maximum is the most you pay for covered medical care in one year. Agents often shorten it to MOOP. Once your spending reaches that limit, your plan pays the full cost of covered services.
Who this is for
- Live with a chronic condition that brings regular specialist care.
- Have surgery, chemotherapy, or a joint replacement on the calendar.
- Rely on a fixed income where one bad year would be hard to absorb.
- Travel often and may need care outside your plan's network.
- Chose a plan on premium alone and never checked the cap.
What you get
In-network maximum
This is your cap when you stay with the plan's contracted doctors and hospitals. It is the number most plans advertise, and it is the one most members reach.
Combined maximum
PPO plans add a second, higher cap that counts in-network and out-of-network care together. If you travel or see doctors outside the network, this is the number that protects you.
HMO plans
Most HMO plans list a single in-network cap. Outside the network, only emergency and urgent care is generally covered, so the network map matters a great deal.
What Is a Medicare Out-of-Pocket Maximum?
Your out-of-pocket maximum is the most you pay for covered medical care in one year. Agents often shorten it to MOOP. Once your spending reaches that limit, your plan pays the full cost of covered services.
It may be the most important number on a Medicare Advantage plan. It is also one of the least discussed. Monthly premiums get the attention, yet this number decides what a hard health year really costs you.
The short version
A Medicare Advantage plan must cap your yearly medical costs. Original Medicare on its own does not.
The cap does nothing in a quiet year. It does everything in a year with surgery, cancer care, or a long hospital stay.
- Every Medicare Advantage plan must set a yearly out-of-pocket limit.
- RequiredEvery Medicare Advantage plan must set a yearly out-of-pocket limit.
- Original Medicare alone has no yearly limit on your share of costs.
- NoneOriginal Medicare alone has no yearly limit on your share of costs.

Why Does Medicare Advantage Have a Cap When Original Medicare Does Not?
Medicare requires every Medicare Advantage plan to set a yearly limit on your costs. Medicare also sets the highest limit a plan may use, and that ceiling is reviewed each year. Many plans choose a lower cap to compete for your business.
Original Medicare was built on a different model. After you meet the Part B deductible, Medicare generally pays 80 percent of the approved amount. You owe the other 20 percent, and nothing stops that share from growing.
Two ways your costs can add up
Original Medicare alone
Steady rules, open-ended risk.
- Yearly cap on your spending
- None.
- Your typical share
- 20 percent of approved Part B costs, with no ceiling.
- Doctor choice
- Any provider in the country who accepts Medicare.
- How people add protection
- A Medigap policy that pays most of the leftover share.
Medicare Advantage
Copays along the way, a hard stop at the top.
- Yearly cap on your spending
- Required, and printed in every plan document.
- Your typical share
- Set copays and coinsurance until you reach the cap.
- Doctor choice
- Usually a network, with referral rules on some plans.
- How people add protection
- Choosing a plan with a lower cap and the right network.
Why the gap matters
Twenty percent sounds small until the bill is large. Twenty percent of a long hospital stay is not a small number. That is the risk a cap is designed to close.
What Counts Toward Your Out-of-Pocket Maximum?
Not every dollar you spend moves you closer to the limit. Only your share of covered Part A and Part B services counts. Knowing the difference keeps your planning honest.
- Deductibles you pay for covered medical services.
- Copays for doctor visits, urgent care, and emergency room trips.
- Coinsurance for hospital stays, surgery, and outpatient procedures.
- Your share of lab work, imaging, and medical equipment the plan covers.
- Monthly premiums never count, not for the plan and not for Part B.
- Prescription drug costs are tracked separately from your medical cap.
- Extra benefits like routine dental or vision usually sit outside the cap.
- Care the plan does not cover at all, which you pay in full.
Drug costs live on a separate track
What you pay at the pharmacy usually does not count toward your medical cap. Your Part D coverage has its own yearly cap on covered drug costs. Medicare sets that amount and adjusts it each year, so confirm the current figure before you enroll.
What Is the Difference Between In-Network and Combined Limits?
Many plans list two limits, and shoppers often read only the first one. The lower number usually applies to in-network care. The higher number covers everything, including care you get outside the network.
How the two limits work
In-network maximum
This is your cap when you stay with the plan's contracted doctors and hospitals. It is the number most plans advertise, and it is the one most members reach.
Combined maximum
PPO plans add a second, higher cap that counts in-network and out-of-network care together. If you travel or see doctors outside the network, this is the number that protects you.
HMO plans
Most HMO plans list a single in-network cap. Outside the network, only emergency and urgent care is generally covered, so the network map matters a great deal.
Where to find both numbers
Open the plan's Summary of Benefits and look near the top. The cap is usually listed on the first page, above the copay list. If you see two numbers, write down both.
How Should You Compare Plans on This Number?
A cap is only useful in context. The right question is not which plan has the lowest number. It is which plan gives you the best trade between monthly cost, network, and worst-case exposure.
A five-step comparison
- 01
Write down each plan's cap
List the in-network cap for every plan you are considering. Add the combined cap when the plan is a PPO.
- 02
Add the yearly premium
Multiply the monthly premium by twelve. Add that to the cap to see your true worst-case year.
- 03
Check the network first
A low cap helps little if your cardiologist is out of network. Confirm your doctors and hospitals before you weigh anything else.
- 04
Price a serious health year
Imagine a surgery and a short hospital stay. Walk through the copays on each plan and see which one holds up.
- 05
Repeat it every fall
Caps, copays, and networks change yearly. An annual review catches those changes before they cost you.
A low premium looks like savings right up until a hospital stay tests the ceiling above it.
How Do You Add a Cap to Original Medicare?
You cannot change how Original Medicare works, but you can cushion it. A Medigap policy pays most of the cost sharing Medicare leaves to you. In practice, that turns an open-ended share into a steady monthly premium.
Two lettered plans go further and include a yearly out-of-pocket limit of their own. Plan K and Plan L both work that way. You share more cost early in the year, then the policy pays covered services in full once you reach its limit.
- Medigap trades a higher monthly premium for far steadier bills.
- You keep access to any provider in the country who accepts Medicare.
- Drug coverage is separate, so you still add a Part D plan.
- Health questions may apply if you apply outside a protected window.
Timing matters in California
California gives Medigap members a yearly window around their birthday to switch policies. The rules are specific, and the window is short. Ask before you assume a change is available to you.
