Start with 3 quick questions

Medicare Advantage availability is local, so we begin with a few basics.

Plan availability can vary by county and service area.

How it works

Medicare Advantage combines Medicare coverage through a private Medicare-approved plan

Medicare Advantage, also called Part C, is another way to receive Medicare Part A and Part B benefits. Most plans also include Medicare drug coverage, and many offer additional benefits.

1

Keep Medicare Parts A & B

You remain in Medicare, but most covered services are provided through your Medicare Advantage plan.

2

Review the local network

Doctors, hospitals, pharmacies and service areas can matter. Network rules differ by plan type.

3

Compare total value

Look beyond premium alone. Review copays, maximum out-of-pocket limits, prescriptions and extra benefits.

Plan structures

Common Medicare Advantage plan types

Your best fit depends on your doctors, prescriptions, travel patterns, health needs and preferred level of flexibility.

HMO

Health Maintenance Organization

Usually emphasizes in-network care and may require referrals depending on the plan.

PPO

Preferred Provider Organization

Typically provides more flexibility to use out-of-network providers, usually at a higher cost.

SNP

Special Needs Plan

Designed for certain qualifying groups, such as people with specific chronic conditions or dual Medicare/Medicaid eligibility.

Other

PFFS / MSA Options

Availability varies. These plan structures have different provider, payment and drug-coverage rules.

What to compare

Don't compare Medicare Advantage plans on premium alone

A plan that looks inexpensive may not be the best fit if your doctors, hospitals or prescriptions do not match its rules.

Special Circumstances
