Key Takeaways

• H5521-272 is the CMS identifier for Aetna Medicare Signature (PPO) in 2026, offering $0 monthly premium and $0 medical deductible, but you must still pay Medicare Part B premium and a $615 drug deductible.
• The plan is only available in seven specific Florida counties (Charlotte, Collier, DeSoto, Highlands, Lee, Manatee, Sarasota), so verify your county before enrolling to avoid coverage gaps.
• Always confirm your doctor accepts this exact plan using Aetna's official provider directory and call their office directly, as networks change yearly and third-party sites may have outdated information.
• The out-of-pocket maximum is $5,500 in-network or $10,100 combined, and monthly premiums and drug costs don't count toward this cap, so review the current Evidence of Coverage before scheduling care.

For 2026, Aetna lists it as Aetna Medicare Signature (PPO). Knowing the details helps you choose a primary care doctor, plan your wellness visits, and avoid surprise bills.

This guide explains what H5521-272 is, what it costs in 2026, where it is offered, and how to use it for primary care and preventive health. It also shows how to confirm that your doctor accepts the plan before you book a visit. Plan details can change each year, so always check the official documents for your own coverage.

What Does H5521-272 Mean?

H5521-272 is a plan ID assigned by the Centers for Medicare & Medicaid Services (CMS). The "H" number identifies the insurance contract. The "272" identifies the specific plan under that contract. You may also see it written as H5521-272-0 or H5521-272-000, depending on the document or website.

For 2026, this ID matches Aetna Medicare Signature (PPO). It is a Medicare Advantage plan, also called Medicare Part C. It includes Medicare Part A (hospital) and Part B (medical) coverage. It also includes prescription drug coverage, known as Part D.

Here is a quick snapshot of what the code tells you:

• Plan type: Medicare Advantage PPO with drug coverage.
• Insurance company: Aetna.
• Plan name for 2026: Aetna Medicare Signature (PPO).
• Coverage: Medicare Part A, Part B, and Part D benefits, subject to plan rules.

H5521-272 Costs and Benefits in 2026

Cost is often the first question patients ask. Based on the 2026 Summary of Benefits, the plan lists a $0 monthly plan premium and a $0 medical deductible. You still must keep paying your standard Medicare Part B premium. Prescription drugs have their own separate deductible.

The table below summarizes the key figures listed for 2026.

Two points deserve attention. First, the out-of-pocket maximum is a yearly cap on covered medical services. Your monthly premiums and prescription drug costs do not count toward it. Second, drug costs depend on the plan formulary, your pharmacy, and your coverage stage. Review the current formulary before you fill a prescription.

Where Is H5521-272 Available?

This plan is only available in certain counties. The 2026 Summary of Benefits lists seven Florida counties in the service area:

• Charlotte
• Collier
• DeSoto
• Highlands
• Lee
• Manatee
• Sarasota

To enroll, you must have both Medicare Part A and Part B. You must also live in the plan's service area. If you live outside these counties, such as in Hillsborough County, this plan is not an option for you. Residents of Tampa and Riverview should look at plans that serve Hillsborough County instead.

How a PPO Plan Works for Primary Care

A PPO, or Preferred Provider Organization, gives you more freedom than many other plan types. You can usually see doctors outside the plan network. However, you will usually pay more when you do. Staying in-network keeps your costs lower and your care simpler.

Before you rely on any plan, check these items:

1. Confirm your doctor is in-network. Use the official provider directory on Aetna's website, then call the office to double-check.
2. Review referral and prior authorization rules. Some services need approval before you receive them.
3. Check specialist and hospital coverage. Make sure the facilities you prefer are in the network.
4. Look up your medicines. Compare your prescriptions to the plan formulary.
5. Read the Evidence of Coverage. This document is the official source for benefits and rules.

Aetna members can also use the secure member website to choose or change a primary care provider. You can review claims and plan documents there as well.

Why Primary Care Matters on a Medicare Advantage Plan

A strong primary care relationship is one of the best ways to get value from your plan. A primary care doctor tracks your health over time. They help manage long-term conditions, order screenings, and coordinate with specialists. This keeps your care organized and can prevent small problems from becoming costly ones.

Good primary care for Medicare patients often includes:

• Annual wellness visits and physical exams
• Blood pressure, diabetes, and cholesterol management
• Cancer screenings and other preventive tests
• Vaccines and prescription management
• Referrals to trusted specialists when needed

How to Verify Your Plan Before You Book a Visit

Plan details change from year to year. Networks, copays, and drug lists can all shift. A few quick checks can save you money and stress.

Follow these steps:

1. Find your plan ID on your member card. Look for H5521-272 or a similar format.
2. Open the current Summary of Benefits and Evidence of Coverage on Aetna's official site.
3. Search the provider directory for your doctor's name and location.
4. Call the clinic and ask if they accept your exact plan, not just the insurance company.
5. Ask about copays for primary care, labs, and screenings before your visit.

Be careful with third-party plan listing sites. Some show enrollment numbers and star ratings that may be out of date. Always confirm time-sensitive details, such as CMS star ratings, with CMS or Aetna directly.

Planning Your Wellness Care Beyond the Basics

Medicare Advantage plans cover many core services. But many people also want a proactive approach to health. That may include weight management, metabolic testing, or advanced preventive screenings. Not every wellness service is covered by every plan, so ask about coverage before you start.

Common Mistakes to Avoid

Plan codes can be confusing, and small errors can lead to big bills. Watch out for these common mistakes:

• Assuming every county is covered. This plan serves only the seven Florida counties listed.
• Skipping the provider directory. A doctor who accepted last year's plan may not accept this year's.
• Ignoring the drug deductible. Your medical deductible is $0, but drug costs work differently.
• Forgetting the Part B premium. A $0 plan premium does not erase your Medicare Part B premium.
• Not reading the Evidence of Coverage. It explains rules that marketing pages often skip.
