Medicare Advantage HMO vs. PPO (2026–2027): Costs and Choice
Bottom Line
A Medicare Advantage HMO may suit care within its network; a PPO offers eligible out-of-network coverage, usually at higher cost. Confirm providers will see you, and compare total annual costs using documents for your intended coverage year.
A Medicare Advantage HMO can fit well when its network includes your doctors and its total costs suit your budget. Consider a PPO when access to out-of-network care matters enough to accept potentially higher costs. HMOs generally restrict routine care to their networks; PPOs generally cover eligible out-of-network services at higher cost.
If you also own a business and are considering an SBA loan, life insurance for an SBA loan is a separate topic to discuss with your lender, unrelated to this Medicare coverage decision.
How HMO and PPO rules affect doctor choice
Both are Medicare Advantage, or Part C, plans. They provide your Part A hospital and Part B medical coverage through a private insurer, usually with Part D prescription coverage. You generally continue paying your Part B premium, even if the plan premium is $0.
| What matters | HMO | PPO |
|---|---|---|
| Routine care outside the network | Generally not covered unless the plan authorizes it or an exception applies | Covered services generally available, usually at higher cost |
| Primary care doctor | Usually required | Not required by the plan |
| Specialist referrals | Usually required, but some plans waive them | Not required by the plan |
| Prior authorization | May apply to specified services | May apply to specified services |
These are general rules; check the individual plan’s documents. Noncovered out-of-network HMO care can leave you paying the full bill. An HMO-POS adds an option for certain out-of-network services, but its scope varies. Do not assume it offers a PPO’s flexibility.
As you explore local Medicare Advantage coverage, start with your home address and county, then narrow the available plans around your care needs. You need both Part A and Part B and must live in the plan’s service area to join.
Verify your doctors before comparing extras
Start by checking whether your doctors are in-network for the exact plan, office location and coverage year. Search the insurer’s directory, then confirm participation with the plan and the provider’s billing office. Accepting Medicare does not establish membership in a particular Advantage network.
Include your hospital, specialists, labs, imaging centers and therapists. Ask about new-patient availability and where a specialist performs procedures. Save the plan name, plan ID, confirmation date and answers.
A PPO also needs a practical access check. For example, Johns Hopkins Advantage MD’s 2026 PPO says noncontracted providers generally do not have to treat members outside emergencies. It recommends requesting a coverage decision before out-of-network care. Confirm that the provider will see you and that the planned service is covered before scheduling.
A real 2026 comparison in Anne Arundel County
Two Medicare Advantage options in Anne Arundel County, Maryland, illustrate the trade-offs within one insurer: Johns Hopkins Advantage MD (HMO) and Johns Hopkins Advantage MD (PPO). Both list the county in their 2026 service areas. These examples explain plan design; they are not a ranking of local plans.
| Published 2026 benefit | Johns Hopkins Advantage MD (HMO) | Johns Hopkins Advantage MD (PPO) |
|---|---|---|
| Monthly plan premium, in addition to Part B | $45 | $95 |
| Medical deductible | $0 | $0 |
| In-network primary care visit | $0 | $5 |
| In-network specialist visit | $45 | $45 |
| Routine out-of-network specialist visit | Generally not covered without an applicable exception or plan approval | 40% coinsurance |
| Annual medical out-of-pocket maximum | $8,950 in-network | $7,550 in-network; $11,300 combined in- and out-of-network |
The HMO’s $45 monthly premium is lower than the PPO’s $95 monthly premium, but their spending limits and out-of-network benefits differ. Review the HMO’s network exceptions before scheduling care outside its network.
The PPO costs $600 more in plan premiums over 12 months, but its in-network medical spending limit is $1,400 lower. If both networks fit, compare your expected visits and procedures. If the PPO gives you access to a must-keep out-of-network specialist, price that care before deciding its higher premium is worthwhile.
For a hypothetical out-of-network specialist service with an applicable Medicare payment rate of $200, the PPO’s 40% share would be $80. This illustrates coinsurance, not an available provider quote. The actual payment rate and covered service determine the amount.
These figures describe 2026 coverage only. Compare each plan’s 2027 documents before choosing coverage for January 2027; do not carry these prices or benefits forward.
Referrals and prior authorization are different
A referral directs you from a primary care doctor to a specialist. Prior authorization is the plan’s approval for a specified service. A plan can waive referrals while still requiring authorization for treatment.
The HMO above illustrates that distinction. Johns Hopkins’ February 2026 provider notice, effective January 1, says its Advantage MD HMO plans do not require PCP referrals for specialty care. The waiver applies to in-network specialists.
When checking Medicare Advantage prior authorization requirements, focus on your expected care: imaging, outpatient surgery, therapy, equipment or ongoing treatment. Ask which services need approval, who requests it and how existing treatment will transition. The example HMO’s Evidence of Coverage identifies authorization requirements for outpatient surgery and rehabilitation, among other services.
Compare a normal year and a costly year
Build an annual estimate using 12 months of plan premiums, your Medicare premiums, expected medical copays and coinsurance, and prescription costs. Include applicable deductibles without counting the same spending twice. A $0 premium alone cannot tell you the total.
For a costly year, compare the medical spending limits and your ability to fund them. In the example PPO, qualifying in-network spending counts toward the combined limit; you do not add $7,550 and $11,300 together. Premiums, Part D drugs and noncovered care fall outside those medical limits; check the document for other exclusions.
Check every prescription, dosage and pharmacy separately, including restrictions such as prior authorization or step therapy. If you want Part D with an HMO or PPO, choose a plan that includes it; you cannot simply add standalone Part D to an HMO or PPO lacking drug coverage.
Plan for travel and a possible move
When using Medicare Advantage away from home, distinguish a scheduled office visit from emergency care. Within the United States, HMOs cover emergencies, out-of-area urgently needed care and temporary out-of-area dialysis outside their networks. Routine travel care needs a separate network or benefit check. PPOs generally provide more out-of-network flexibility, but confirm the provider and price.
For extended stays, check the Evidence of Coverage for service-area absence rules and any visitor benefit. For international travel, verify any foreign emergency benefit separately; Medicare Advantage generally does not cover care abroad.
A permanent move outside the service area creates a Special Enrollment Period. Notify the plan before moving so you can arrange replacement coverage.
Prepare your comparison and confirm when you can switch
Annual Medicare Open Enrollment runs October 15–December 7, with changes effective January 1 of the following year. People already in Medicare Advantage can also make one change during January 1–March 31, effective the first of the month after the plan receives the request. Other enrollment opportunities depend on your circumstances.
If neither network fits, consider Original Medicare with separate Part D and, if available to you, Medigap. Medigap—also called Medicare Supplement—helps pay Original Medicare cost sharing. Annual Medicare Open Enrollment does not generally guarantee Medigap acceptance without medical underwriting. Confirm federal protections and any additional state rights before leaving Advantage.
To compare Medicare Advantage plans for your doctors, gather your county and ZIP code, doctors’ names and locations, prescriptions and dosages, preferred pharmacies, travel plans and expected procedures. Use Medicare’s comparison tools to review available plans and drug-cost estimates, then verify networks and authorization rules directly. Choose the plan whose access rules you can use and whose expected costs and spending limits you can afford.
