Under Medicare Advantage out-of-network rules, whether your plan pays for care from a non-contracted provider depends almost entirely on your plan type and the situation. HMO plans generally pay nothing for out-of-network care except in an emergency. PPO plans cover out-of-network care but charge you higher coinsurance, a higher deductible, or both. Every Medicare Advantage plan, regardless of type, must cover emergency and urgent care anywhere in the country.
HMO Plans Draw a Hard Line
If you have a Health Maintenance Organization plan, you need to get your care from the plan’s contracted providers. Most HMOs also require you to pick a primary care doctor who refers you to specialists inside the network. See a doctor outside the network for anything other than an emergency or urgently needed care, and the plan pays nothing. You owe the full bill.
That’s the tradeoff for lower premiums and predictable copays. Less flexibility, lower cost.
HMO-POS: A Partial Exception
Some HMOs include a “point-of-service” option that lets you go outside the network for certain covered services at higher copays or coinsurance.1Medicare.gov. Understanding Medicare Advantage Plans You pay more, but the plan still shares the cost. If you occasionally want access to outside specialists without jumping to a PPO, HMO-POS splits the difference.
PPO Plans Cover Out-of-Network Care at a Higher Price
Preferred Provider Organization plans must reimburse all covered benefits whether you see an in-network or out-of-network provider.2eCFR. 42 CFR 422.4 – Types of MA Plans You don’t need referrals, and you can see any Medicare-eligible provider willing to treat you.
The cost difference is substantial. In-network care might carry 20% coinsurance; the same service out of network could cost 40% or more. Many PPO plans also apply a separate, higher deductible to out-of-network services. For ongoing treatment or an expensive surgery, that gap adds up fast.
Two Out-of-Pocket Maximums
PPO plans must set two separate spending caps. One limits what you pay in-network. A higher combined cap covers both in-network and out-of-network costs together. For 2026, the in-network maximum cannot exceed $9,850, and the combined maximum cannot exceed $14,750. Plans can set lower limits, not higher ones. Part D prescription drug costs don’t count toward either cap.
Balance Billing Is Capped
An out-of-network provider treating a Medicare Advantage member cannot charge whatever they want. Non-contracted providers must accept, as payment in full, the same amount they could collect under Original Medicare.3Centers for Medicare & Medicaid Services. Provider Payment Dispute Resolution for Non-Contracted Providers In practice, that means no more than 15% above the Medicare-approved amount for the service. You still owe your plan’s out-of-network coinsurance, but the provider can’t pile unlimited charges on top.
This protection comes from Medicare’s own rules. The No Surprises Act’s balance billing restrictions do not apply to Medicare enrollees, because Medicare has its own longstanding protections.
Emergency and Urgent Care Are Covered Anywhere
Network rules do not apply in a genuine emergency. Every Medicare Advantage plan must cover emergency and urgently needed services whether you receive them inside or outside the network, and whether or not you obtained prior authorization.4eCFR. 42 CFR 422.113 – Special Rules for Ambulance Services, Emergency and Urgently Needed Services, and Maintenance and Post-Stabilization Care Services Plans must use the “prudent layperson” standard: if a reasonable person with average medical knowledge would believe the symptoms needed immediate attention to prevent serious harm, the plan must cover the visit based on those initial symptoms. The final diagnosis doesn’t change that.
Your cost-sharing for an out-of-network emergency visit is capped at the lower of two amounts: whatever the plan charges for in-network emergency care, or a per-visit dollar maximum CMS sets each year. For 2026 those caps are $115, $130, or $150 per visit depending on your plan’s out-of-pocket maximum tier.4eCFR. 42 CFR 422.113 – Special Rules for Ambulance Services, Emergency and Urgently Needed Services, and Maintenance and Post-Stabilization Care Services The same rule applies to urgent care received while you’re outside the service area.
Post-Stabilization Care
After the emergency room stabilizes you, continued treatment at that out-of-network facility is still the plan’s responsibility in several situations. The plan covers it if it pre-approves the care. The plan covers it if you or the treating doctor requests pre-approval and the plan doesn’t respond within one hour. And if the treating doctor and the plan’s doctor can’t agree on a care plan, and no plan physician is available by phone, the treating doctor can keep providing covered care until that changes.4eCFR. 42 CFR 422.113 – Special Rules for Ambulance Services, Emergency and Urgently Needed Services, and Maintenance and Post-Stabilization Care Services
Your cost-sharing for post-stabilization care cannot exceed what you’d pay in-network. The plan’s responsibility ends when a plan physician takes over, both doctors agree on next steps, or you’re discharged.
Getting Out-of-Network Care Approved in Advance
When you need non-emergency care from a provider outside the network, request what CMS calls an “organization determination” before the service happens. Include medical records and a clear explanation of why that particular provider is necessary. Most plans accept these requests through the provider’s office electronically or by mail.
Deadlines depend on the type of request. For services subject to prior authorization, the plan must decide within 7 calendar days as of January 1, 2026. For services not subject to prior authorization, the standard deadline is 14 calendar days.5eCFR. 42 CFR 422.568 – Standard Timeframes and Notice Requirements for Organization Determinations If a doctor certifies that waiting could seriously harm your health, you can request an expedited determination; the plan must resolve it within 72 hours. The plan can extend the standard deadline by up to 14 days if you ask for the extension or if the plan needs outside medical evidence that could reverse a denial.
If the plan approves, the written notice spells out which services are authorized and what you’ll owe. Keep that letter. It’s your proof the plan agreed to the terms.
Confirm Network Status Before Every Appointment
Every Medicare Advantage plan must maintain a directory of contracted providers with names, addresses, phone numbers, and specialties.6eCFR. 42 CFR 422.111 – Disclosure Requirements Starting in 2026, plans must update directory information within 30 days of learning about a change. Check the online directory using the provider’s full name and the specific clinic address, because a doctor can be in-network at one office and out-of-network at another.
Don’t stop at the website. Directories lag behind real contract changes, and a directory error that sends you to an out-of-network provider still leaves you with a bigger bill. Call the plan’s member services number and confirm the provider’s network status for the specific location and the date of your appointment. Ask the representative to note the confirmation in your file. That record gives you leverage if a billing dispute comes up later.
When Your Provider Leaves the Network Mid-Treatment
Doctors and hospitals drop out of Medicare Advantage networks more often than most members expect, sometimes mid-year. If you’re a new enrollee already in the middle of active treatment, federal rules give you a safety net: the plan must provide at least a 90-day transition period to continue your current treatment, even if the provider is out of network.7eCFR. 42 CFR 422.112 – Access to Services During that period, the plan cannot require a new prior authorization for the course of treatment that was already approved.
Beyond that 90-day window, plans must honor existing prior authorization approvals for as long as medically necessary to avoid disrupting care.7eCFR. 42 CFR 422.112 – Access to Services If an oncologist was authorized for a six-month chemotherapy regimen and then leaves the network in month two, the plan cannot simply revoke the approval. Specifics vary by plan, so check your Evidence of Coverage. If you believe your plan is cutting off treatment prematurely, that’s worth escalating through the appeals process.
Traveling Outside Your Service Area
Emergency and urgent care are covered anywhere in the country, no matter how far from your service area. Routine care is different. Most Medicare Advantage plans will not cover non-emergency services outside the service area unless the plan specifically includes a travel or visitor benefit.
Some plans do offer travel benefits for care while you’re temporarily away from home, sometimes for trips up to 12 months. These benefits vary: some cover only certain types of care, some limit which geographic areas qualify, and most charge higher cost-sharing for out-of-area services. If you spend winters in another state or travel often, ask about these benefits before enrolling.
There’s a hard deadline worth knowing. If you’re continuously outside your plan’s service area for more than six months, the plan will generally disenroll you automatically. At that point you’d need to enroll in a plan available where you’re living or go back to Original Medicare.
Some insurers that run Medicare Advantage PPO plans in multiple states offer reciprocal network arrangements that let you see contracted providers in other states at in-network rates. Blue Cross Blue Shield’s Medicare Advantage PPO plans, for instance, let members access contracted MA PPO providers in other BCBS service areas. If cross-state coverage matters to you, ask whether the plan has any reciprocal network sharing before you enroll.
Appealing a Denied Out-of-Network Request
If your plan denies an out-of-network authorization, you have appeal rights. Most people give up too early. Plans overturn their own denials at Level 1 more often than you’d think, and the independent reviewer at Level 2 reverses plan decisions at even higher rates.
You have 65 days from the date on the denial notice to ask your plan to reconsider.8Medicare.gov. Appeals in Medicare Health Plans Include any additional medical records and a letter from your doctor explaining why the out-of-network care is medically necessary. If your health requires a fast answer, ask for an expedited reconsideration; the plan must decide within 72 hours. When a physician requests expedited review, the plan has to grant the faster timeline.9Centers for Medicare & Medicaid Services. Reconsideration by the Medicare Advantage (Part C) Health Plan
If the plan upholds the denial, it must automatically forward your case to an Independent Review Entity run by MAXIMUS Federal Services. This review is independent of your insurance company. The IRE must issue a decision within 30 calendar days for standard pre-service requests or 72 hours for expedited requests.10Centers for Medicare & Medicaid Services. Reconsideration by Part C Independent Review Entity (IRE) You don’t need to file anything at this level; the plan sends the case file for you.
Three additional levels of appeal exist beyond the IRE: a hearing before an Administrative Law Judge, review by the Medicare Appeals Council, and finally a lawsuit in federal district court. Each has its own dollar threshold and 60-day filing deadline. Few cases reach those levels, but the option matters when the stakes are high enough.
