The number of Medicare Advantage plans available in any given zip code can be overwhelming. Dozens of options, each with its own premium, network, benefit list, and fine print. The plan-comparison tools help — but only if you know what to look for. Here are the five factors that actually matter.
This is the first check, not the last. Before you compare premiums or benefits, look up your current doctors in the plan's provider directory. A Medicare Advantage plan with a $0 premium is worthless to you if your cardiologist, oncologist, or primary care doctor is not in-network.
Most Advantage plans are HMOs (requiring you to stay in-network for non-emergency care) or PPOs (allowing out-of-network use at higher cost). Know which type you are looking at and what the out-of-network rules are.
Provider directories are not always current. After confirming in the plan's directory, call the doctor's office directly and ask whether they are accepting new patients on that specific plan.
Most Medicare Advantage plans include Part D drug coverage. Before enrolling, enter your exact medications (name, dosage, and frequency) into the plan comparison tool at medicare.gov/plan-compare. Look at the formulary tier for each drug — the same medication can be Tier 1 (very low cost) on one plan and Tier 3 (significantly more expensive) on another.
Do not just check whether the drug is covered. Check what you would actually pay for it under each plan you are comparing.
Medicare Advantage plans have an annual out-of-pocket maximum — the most you would pay for covered services in a calendar year. In 2026, federal law caps this at $9,350 for in-network services and $14,000 for combined in/out-of-network. Many plans have lower caps, but they can still range widely.
This number matters most if something goes seriously wrong — a hospitalization, a surgery, a cancer diagnosis. A $0-premium plan with a $9,000 out-of-pocket max may cost more in a bad year than a $100/month plan with a $3,500 cap. Model the worst case, not just the typical month.
Dental, vision, hearing, fitness memberships, over-the-counter allowances, transportation to appointments — these benefits are often cited as major advantages of Medicare Advantage, and they can be genuinely valuable. But only if you actually use them.
Before giving credit to a plan's "dental benefit," look at what it actually covers. Many plans offer preventive dental (cleanings, X-rays) but limited or no coverage for major restorative work. An eyewear allowance of $100 per year may not go far if you need progressive lenses. Understand exactly what each benefit provides before treating it as meaningful plan differentiation.
Medicare rates Advantage plans on a 1–5 star scale based on quality of care, member experience, and customer service. Look for plans with 4 or 5 stars. Higher-rated plans tend to have better care coordination, fewer problems with prior authorizations, and better member satisfaction. Star ratings are available at medicare.gov.
Also check whether the plan has been in your market for a number of years or is relatively new. New plans sometimes offer attractive first-year benefits and then significantly restructure in subsequent years.
The best Medicare Advantage plan is not the one with the most benefits or the lowest premium — it is the one that covers your doctors, covers your drugs at a reasonable cost, and protects you from catastrophic cost in a bad year. Use medicare.gov/plan-compare and input your actual medications and doctor names before making any decision.
Medicare Advantage plans can change their premiums, benefits, formularies, and networks each year. This is why the Annual Enrollment Period (October 15–December 7) matters. Review your plan every year during this window, even if you are happy with it. What worked well in 2026 may look different in 2027.
