I signed up for a Medicare Advantage HMO, and I'm wondering if I can see a cardiologist out of network without paying everything myself.

Question

Bill Filer · Accepted Answer

This on can be tricky.

Using an HMO plan typically means you would want to stay within the network in order to keep your costs as low as possible. If you see a doctor outside of the network, you could end up paying the full cost for that care. There could be some exceptions if this was an emergent care issue while out of network. Be careful seeing an out of network doctor on an elective basis.

Some HMO plans are Point of Service (POS). A POS plan may allow you go out of network for some things. If it is a POS plan, you can probably count on paying a higher price if you choose an out of network provider, however. 

Call your plan provider and double check before having the services provided. It's really the only way to know for certain what you're facing. Wish you best!

Gary Church · Answer

Medicare Advantage HMO has no out-of-network coverage,  except for emergency services. So, if you want to see a cardiologist out of network, you'll have to pay the cost.

Steve and Sue Brauer · Answer

So the question is, someone signed up for a Medicare Advantage HMO and they're wondering if they could see a cardiologist out of network without paying everything themselves. The quick answer to that is no. If they're not in the HMO network, the carrier, the insurance company, is not going to pay for it. But that's the reason why some Medicare Advantage plans offer a PPO plan, which has the ability to go out of network. I gotta tell you, most times, most cardiologists are gonna be in one of the HMO networks. Not always, but most times. And if they're not, they're typically in the PPO network, so they can be seen. It's a matter of working closely with your Medicare advisor and having them help you navigate that.

George Ibanez · Answer

If you have an HMO, you can only see doctors that are in the network, and they will not pay anything if you go to your cardiologist or any other doctor out of the network.
If you want the flexibility to go to doctors out of the network, you will have to switch to a PPO or to a Medicare supplement plan.

Mark Maliwauki · Answer

You would simply need to call your HMO and find out. It is likely that you will pay out of network charges if you choose to get care outside of your HMO network although there can be exceptions made if you are specifically referred to a Dr outside of the network.

Pamela Masters · Answer

An HMO only allows you to stay within the network of doctors. I’d you go outside of the network you would have to pay for the whole visit yourself.

John Becker · Answer

With a standard Medicare Advantage HMO plan, you will generally have to pay the full cost for an out-of-network cardiologist unless it is an emergency or you have specific plan features. 

HMO plans typically require you to receive all non-emergency care within a specific network of doctors and facilities. If you choose to go outside the network, the plan usually will not cover any of the cost, leaving you responsible for the entire bill

Network Exception/Prior Authorization. If your plan does not have an in-network cardiologist who can provide the necessary treatment, your primary care physician (PCP) can request a "network exception" or "prior authorization" from the plan. If the plan approves the request before you receive care, the service may be covered at the in-network rate.

Unfortunately, that is one of the down sides of an HMO plan. You must see providers that are in-network. You would have to pay the whole thing out of pocket. You could explain to the cardiologist's office your situation, and they might be able to give you a cash price discount. It's worth asking if you really want to see that specific one.

Joel Gregory Craven · Answer

Not usually unless your HMO has a POS (Point of service) for medical doctor visits. Usually the HMO will refer you of network only if you have a condition that can not be treated in network. An example of that would be like if you had a rare condition (rare cancers) or maybe a rare blood disorder. However normal stuff is treated in network. Another option is ask the doctor if he would like to come in network with carrier? Then call your agent and have that person follow up with the carrier net-ops manager to see if they would offer the doctor a contract. Of course the obvious, you could change plans to a plan that the doctor accepts. Usually during AEP or a special election.

That's a great question. Unfortunately the HMO Medicare Advantage plans do not have out-of-network benefits. This means you would have to pay 100% out-of-pocket for the cardiologist visit. When reviewing your next year Medicare Advantage plan, you want to look for a plan that either the cardiologist is in-network with to have coverage (and all your other doctors), or change to a PPO Medicare Advantage plan because those plans do have out-of-network benefits so that you don't have to pay a 100% yourself.

With a Medicare Advantage HMO plan, you typically need to use a network of doctors and specialists to receive covered services. If you want to see an out-of-network cardiologist, you may have to pay the full cost of the visit yourself, as HMO plans usually do not cover out-of-network care except in emergencies.

However, some plans may have specific exceptions or allow for out-of-network referrals under certain circumstances. It's best to check your specific plan details or contact your insurance provider directly to understand your options and any potential costs involved.

An Advantage HMO will require that you must get all of your services from in network providers. If you want the ability to see providers that are out of network and still have it be covered, but generally at a higher cost to you than and HMO, you will need to select an Advantage PPO plan instead. The downside of the PPO plans are that generally the copays and cost shares are higher, along with the annual maximum out of pocket. They tend to also have smaller allowances for extra benefits such as dental, vision, hearing, OTC, etc.

Unless you need an immediate visit to a cardiologist, during the upcoming fall Annual Open Enrollment period, you can very easily change over to another Advantage plan. This is known as a PPO or a Preferred Provider Organization. This will become effective on 1/1/26. It allows you to go both IN & OUT of your network though the “out” visit will be a greater copay cost to you. However, if you are “concerned” about your heart, don’t wait! See that specialist now!

No, most likely not. You would pay all costs of the claim if deemed out of network.

Plans are insured or covered by a Medicare Advantage (HMO, PPO and PFFS) organization with a Medicare contract and/or a Medicare-approved Part D sponsor. Enrollment in the plan depends on the plan’s contract renewal with Medicare. We do not offer every plan available in your area.

Some HMO plans may allow you to see a specialist out-of-network, but you will have higher out-of-pocket costs. It may all depend on the plans within your area.

I highly recommend sticking with in-network doctors to keep your medical expenses lower. HMO plans typically do not cover any costs for out-of-network doctors.  If you wish to see doctors outside the plan's network, a PPO would be the way to go.

Unless there are special circumstances, you are typically required to see in-network providers if you're enrolled in a Medicare Advantage HMO plan.

Leslie Kaz · Answer

So you joined the Medicare Advantage HMO and now you're wondering, what if I need to see a specialist like a cardiologist who's not in my network? Can I still go? That's a great question. The short answer is you can, but you'll probably pay the full bill out of pocket. Here's why: HMO stands for Health Maintenance Organization. That means your care's managed through a network of contracted doctors and hospitals. If your cardiologist isn't part of that network, the plan doesn't have a contract to pay them, and Medicare can't step in to cover it either.

Now, there are exceptions. Emergency and urgent care, you're covered anywhere in the U.S. Referrals or prior approvals are needed if your primary doctor or the plan gives written authorization to see someone out of network. It may be covered at in-network rates, but those are the exceptions, not the rule. So before you make that appointment, always call your plan or check your member portal. Ask, "Is doctor XYZ in my network?" If not, "Can I get a referral or prior authorization?"

And honestly, this is where having a good Medicare agent makes all the difference. The right advisor can help you choose a plan that includes your doctors from the start, especially specialists like cardiologists. So yes, you can go out of network with an HMO, but it's usually on your dime. The goal is to pick the right plan before you need that care. That's what we help people do every day. If you're not sure whether your doctors are covered, reach out. We'll help you find out before you get surprised by a bill.

In the meantime, if you want to see that provider, ask if they have a cash discount and be prepared to transition to an in-network doctor if you need anything more than just a check-up.

If you have a Medicare Advantage Plan (MAPD) HMO plan, it simply means if you seek provider service in network you're covered.  If you go out of network, you'd have no coverage and would self-pay.  Essentially all MAPD plans provide worldwide coverage for Urgent Care and Emergency.

If a PPO is offered, covered in and out of network but at a higher cost share than in network.  I'd suggest if you do go to an out of network provider, try to seek a referral from your PCP and have all or as much as possible testing service at an in-network provider.

With a Medicare Advantage HMO, you generally cannot see an out‑of‑network cardiologist unless it’s an emergency and if you go anyway, you’ll usually pay the full cost yourself. HMOs are Health Maintenance Organizations and require you to stay in‑network and get referrals, so the safest way to see a cardiologist is to choose one who’s contracted with your plan. If staying with your current cardiologist is important, we can look at PPO or HMO‑POS plans that allow out‑of‑network visits at a lower cost.

Out of network. You can see a cardiologist out of network but expect to pay more out of pocket. In that scenario original Medicare kicks in and should cover 80% of cost. For example, a doctor visit might cost $200 dollars, Medicare would pay $160 dollars, and you pay $40. In addition, physicians reserve the right to charge an additional 15% above what Original Medicare covers. Out of network, no problem but expect to pay more out of your pocket. If you like that doc, perhaps research other plans where your favorite doc or specialist is IN network.

Short answer, no, not typically. There are VERY limited exceptions, like if there is no in network cardiologist in a defined radius of your location, but they are very rare. In most cases, your plan will have a number of specialists you can see in network. If you REALLY want to see one out of network, you typically will have to pay out of pocket. 

You can also talk to your agent and see if there are any Special Election Periods available to you where you can switch to another plan that has your preferred doctor in network. There are often Special Election Periods available so it never hurts to talk to your agent and see what they can do to help.

Only if the cardiologist is in the plan’s network. Specialist visits normally have a copay which can vary by plan, but they must be a network doctor or you will be responsible for paying the entire cost of services.

Yes, in most cases, a Medicare Advantage HMO recipient who chooses to see a cardiologist outside the plan's network for non-emergency care will have to pay the full cost. 
Consider this: HMO plans generally require you to receive all non-emergency medical care and services from providers within their specific network. These providers have agreed to the plan's negotiated rates and terms.
Their is No Out-of-Network Coverage: If you voluntarily go out of network, the plan typically will not cover any of the costs, making you responsible for the entire bill.
 There is one Exception (Emergency/Urgent Care): The only exceptions are medically necessary emergency care, urgent care, or out-of-area dialysis, which all Medicare Advantage plans must cover at in-network rates, regardless of the provider's network status.
 Prior Authorization/Referral Exception: In some rare cases, if a specific required specialist (like a specific type of cardiologist) is not available within the plan's network, your primary care physician (PCP) can request a prior authorization or network exception from the plan. If approved, the service might be covered, but this must be done before you receive the care. So definitely discuss with your PCP.

With most Medicare Advantage HMO plans, you would not be allowed to see your cardiologist if they were out of network and expect your plan to cover anything. There are a limited amount of HMO plans that do offer out of network benefits for non emergencies so you could see if your plan allows that.

Richard Norcross · Answer

If you are in a Medicare Advantage HMO you normally can not go out of network. You will most likely have to pay for the full bill yourself unless it is an emergency.

Shahnaz Razvi · Answer

Most HMO's have a requirement to see a Primary care provider and get a referral to see a specialist. You can see network specialists in the plans network.

If you want to see an out of network specialist this is sometimes available within a PPO plan at a higher cost. But will not be customarily covered under an HMO.

Velvet Ohlen · Answer

The best course of action is to call your healthcare plan to find out what it would cost to see an out-of-network cardiologist. Often, the expense isn’t significant; sometimes just a few extra dollars.

Tim J Harris · Answer

Generally, with an HMO, there are no benefits outside the network... but there are exceptions... and it can be complicated.  Exceptions may include emergency situations, continuity of care, a specialty that the HMO does not have in network, etc.  Read your plan's summary of benefits and other plan details, then call the customer service line to inquire.  Also, there are Single Case Agreements where an out of network doctor obtains authorization to to treat a specific person for a specific condition for a specific period of time with in-network benefits.  You have to ask.

Tanisha Coffey · Answer

Your Medicare Advantage HMO has a specific network of physicians, laboratories, hospitals, etc. If you stay in-network, you will be responsible for costs as expected based on your plan with cost-sharing from your Medicare Advantage provider. If, however, you opt to see an out of network physician, your plan won't cover that. The full financial responsibility will fall on you.

Sophia Davis · Answer

Typically, with an HMO, you are responsible for all costs when using out of network services. Some exceptions may be made in certain circumstances. You can each out to the carrier and request a "Network Exception". There are no guarantees, but it's an option.

Tyler Coleman · Answer

Generally except for in emergency situations, HMOs require you to stay in network in order to get services covered. If you choose to see an out of network doctor you will be responsible for the costs.

John Hawk · Answer

Short answer: probably not — HMOs are the most restrictive plan type for out-of-network care.
Here’s the breakdown:
How HMO out-of-network rules typically work:
In most MA HMOs, out-of-network care is simply not covered except in two situations:
	•	True emergencies (stabilization care is always covered regardless of network)
	•	Urgent care when you’re temporarily outside your plan’s service area
Outside those two exceptions, if you see an out-of-network cardiologist, you’re typically paying 100% out of pocket.
Your options to see a cardiologist:
	1.	Ask your PCP for an in-network referral — HMOs require this anyway. Your PCP coordinates specialist access within the network.
	2.	Check if your plan has a “cardiologist gap” — if no in-network cardiologist is available within a reasonable distance, your plan may be required to authorize out-of-network care at in-network cost-sharing. This is called a network adequacy requirement.
	3.	Request prior authorization for out-of-network care — in rare cases plans approve it when no in-network specialist is available.
	4.	Consider switching plans — if ongoing specialist access is a priority, a PPO gives you out-of-network flexibility (at higher cost-sharing, but not 100%). You’d need to wait for the MA Open Enrollment Period (Jan 1–Mar 31) or AEP in the fall.
Practical first step:
Call the Member Services number on your plan card and ask specifically: “

Chris Prang · Answer

Not likely. 

You would need your HMO to be a true POS (Point Of Service) HMO that allows you to see out-of-network providers and still have some coverage.

Or, if your HMO doesn't happen to have a cardiologist in the network, then you might be able to get an exception to see an out-of-network one and be covered. This would take a prior approval/authorization from the HMO company.

Or, if your PCP recommends/refers a cardiologist that is out-of-network, and they are willing to go to bat for you and get the insurance company to get that cardiologist approved.

I hope that helps.

David Fiveash · Answer

Medicare Advantage HMO do not have any out of pocket coverage unless you get prior authorization by the plan or if have the HMO point of service do offer some out of network coverage.

Scott Klag · Answer

Generally, in an HMO you would not be able to see an Out of Network provider without some type of special consideration. You should always check with your agent or your plan to see if there are exceptions.

Kyra Baldwin · Answer

Typically, HMO plans only cover services provided in-network, so unless stated otherwise, it is not advised to see providers out of network.

Rob Baer · Answer

You would be responsible for all expenses from any out of network doctor for all HMO plans unless it is a HMO POS for that particular issue such as cardiology. Meaning that the plan has insufficient cardiologist in network (minimum 2), and must allow beneficiaries to see outside cardiologist due to lack of in-network doctors.

Gabrielle Sones · Answer

Typically, with an HMO plan you must stay within your network unless it's a life-threatening emergency for coverage. If you are on an HMO without any out of network coverage you will pay out of pocket for those costs.

Michael Cavanaugh · Answer

When you choose an HMO, you agree to see all doctors in the network. There is no coverage out of network, it would be all costs to you. You still have time to change your plan during this OEP to a PPO. I can help you if you are in my service area. PA, NJ, DE.

Nicolas Johnson · Answer

no you cannot, unless the plan allows an exemption. In this situation, you more than likely would have to see a cardiologist within the HMO network without having to pay everything out of pocket.

Alaina Hunt · Answer

If you're enrolled in a Medicare Advantage HMO plan, your ability to see an out-of-network cardiologist without incurring full out-of-pocket costs is generally limited. HMO plans typically require you to use healthcare providers within their network for non-emergency services. Visiting an out-of-network specialist without prior authorization often means you'll be responsible for the entire cost of care.

Vernon Pate · Answer

1. Always check your Statement of Benefits first.

2. Some HMO plans may allow "out-of-network" services. But most do not.

Barbara Hawes · Answer

It seems that you already are aware that HMOs require that you stay in network.  The only exceptions to this are for urgent care,  emergencies, or in certain cases where your insurance company has pre-authorized the out of network provider.   Even so, out of network providers can balance bill, so you may still end up paying a substantial part of the cost.  For more freedom to choose that cardiologist, change to a PPO at the next open enrollment unless you have a qualifying event that opens you to a special enrollment.

Brian Maiz · Answer

With an HMO, it's tough but there are exceptions. HMOs are built around a network. Unlike a PPO, they generally don't cover out-of-network care except in a true emergency, or urgent care when you're away from home. Outside of those, if you see a cardiologist who isn't in your plan's network, you're likely paying the full bill yourself.

Most HMO's require you to get a referral from your primary care doctor before seeing any specialist, including a cardiologist. Skipping that can create coverage problems even when the doctor is in-network.

If you're already working with a cardiologist you trust, this is really important to sort out before looking at plan.  We can sit down and confirm your doctor's network status, and make sure the referral process is all squared away and that you're not hit with any unexpected expenses.

Carl-Daniel Cole · Answer

With a Medicare Advantage HMO, you typically need to see providers within the plan’s network. Seeing an out-of-network cardiologist usually means you’ll pay the full cost unless it’s an emergency. It’s best to check with your plan directly for any exceptions.

Deborah Krump · Answer

If you are in an HMO, you will not have coverage when you go out of network. If you can choose a PPO Medicare Advantage plan, that would give you the ability to go out of network and have coverage, but with more expense. 
In the fall open enrollment, AEP, you can change your Medicare Advantage choice more than once. The deadline for a final decision is December 7th.
Hope that helps!

Elisa Forte · Answer

Unfortunately, not if you have a Medicare advantage HMO you have to use in network doctors and get referrals most likely from your primary care physician although there are Medicare advantage plans that are PPO‘s preferred provider organizations which allow you to go in and out of network at a higher cost. If you use the out of network, you should ask your agent if if there is a special election that you can use to change your plan if that’s what you’re looking to do

Dawn Gonsoulin · Answer

Unfortunately no,  Medicare Advantage HMO plans follow a certain network of doctors.  If you decide to see a doctor outside of the network, then you will be responsible for all charges associated with the service.

Susan Rittenberry · Answer

Unfortunately, no. An HMO plan requires that you see physicians that are in-network only. Generally your PCP can help find an in-network provider, but your plan will not pay for services from physicians who are out-of-network.

Sunil Bhawnani · Answer

It all depends what type of HMO policy you have. If it is a straight HMO, usually there is not an option for out of network and would have to come out of your pocket.

Joan E Kealy · Answer

If you see a cardiologist who is not in your HMO’s network, your plan usually will not pay anything for that visit, however, Some HMOPOS (Point-of-Service) plans may allow limited out-of-network services with higher cost-sharing; so it depends on the exact plan.

Lauren Orlosky · Answer

It is always best practice to refer to your plan's Evidence of Coverage. If your plan has POS feature or Point of Service, you may be able to receive some services out-of-network but for a higher cost share. In general regarding HMO, you will need to stay in the plan's network for your item, test, service to be covered. If you go out-of-network, then you will be responsible for all costs.
