Medicare Advantage Plans in Washington

Page Reviewed / Updated - May 12, 2020

Medicare Advantage plans are a comprehensive alternative to Original Medicare. These plans, which may also be referred to as Medicare Part C or MA plans, are offered by private health insurance companies approved by Medicare. Like Original Medicare Parts A and B, Medicare Advantage plans cover hospital and medical costs. They may also feature additional covered services, such as prescription drug, hearing, vision and dental coverage. Unlike Original Medicare, Medicare Advantage plans vary in out-of-pocket limits, coverage options and availability.       

Medicare Advantage plans, which were first offered in 1997, have become increasingly popular in the past decade and comprise a significant part of the Medicare program. Nationwide, roughly 34% of all seniors are enrolled in a Medicare Advantage plan. In Washington, the stats are comparable, with about 32% of seniors opting for a Medicare Advantage plan over Original Medicare. Medicare Advantage is most popular in Spokane, Lewis, Thurston, Mason and Whatcom Counties, where between 31%-40% of seniors are enrolled in a Medicare Advantage plan. Less than 1% of seniors in Garfield, Ferry, Lincoln, Klickitat and Pend Oreille Counties have Medicare Advantage plans.  

Washington seniors who are interested in exploring Medicare Advantage plans have several insurance providers and plans to choose from. In some cases, plans and benefits vary by county. In Washington, there are five main types of Medicare Advantage plans, including PPO, HMO, SNP, PFFS and MSA plans. In this guide, we’ve outlined these five plan types, prescription drug coverage of Washington seniors enrolled in Medicare Advantage and when enrollment is open. We’ve also included Medicare resources for Washingtonians who want assistance in finding the best plan type for their needs and budget. 

About Medicare Advantage Plans in Washington

Types of Medicare Advantage Plans

Medicare Advantage features several different plan types for seniors in Washington to choose from. These include Preferred Provider Organizations, Health Maintenance Organizations, Special Needs Plans, Private-Fee-for-Service plans and Medical Savings Account plans.    

Preferred Provider Organizations   

PPO plans have network hospitals and health care providers with whom the health insurance company has negotiated special rates for services. Members pay less when they use doctors, specialists and hospitals that are within their PPO plan’s network. While coverage is typically available for out-of-network providers, out-of-pocket costs are generally considerably higher. In most cases, PPO plans cover prescription drugs and the member isn’t required to choose a primary care doctor and doesn’t need a referral to see a specialist.    

Health Maintenance Organizations 

HMO plans also feature in-network health care providers and hospitals that members must receive care from to have their medical bills covered. Some plans allow for out-of-network emergency care and out-of-area urgent care and dialysis, as well as some types of services. Under normal circumstances, if a member goes out-of-network for medical care, they are responsible for the full cost. In most cases, members with HMO plans are required to choose a primary care doctor and receive a referral to see a specialist. Most HMO plans provide prescription drug coverage.  

Special Needs Plans 

SNPs are exclusively for members who have certain characteristics or diseases, such as those who live in nursing homes, those who are dually eligible for Medicare and Medicaid and those who have a specific chronic condition, such as dementia or diabetes. These plans have benefits, drug formularies and provider choices that are tailored to fit the needs of the groups they serve. They have in-network hospitals and health care providers that members must receive care from to have services covered, except in the event of an emergency or urgent care or if they have end-stage renal disease and need dialysis outside of their plan’s service area. All SNPs are required to provide prescription drug coverage, and in most cases, members need a referral to see a specialist.  

Private-Fee-for-Service Plans 

PFFS plans are unique from other Medicare Advantage plans in that the health insurance company, not Medicare, determines how much it pays the health care provider and how much the member pays for a covered service. Members can use their plan at any health care provider that accepts that plan’s payment terms. Nonnetwork providers can accept the plan’s payment terms on a patient-by-patient, case-by-case basis, and they may refuse to accept the plan’s coverage for a particular service. All PFFS plans must cover any service that’s considered medically necessary under Original Medicare, and some plans cover prescription drugs. Members don’t need to choose a primary care physician and they don’t need a referral to see a specialist.  

Medical Savings Account Plans 

An MSA plan is a type of Medicare Advantage plan that combines a high-deductible health insurance plan with a medical savings account. These plans, which are also called consumer-directed Medicare Advantage plans, are similar to Health Savings Account plans that are available outside of Medicare. They feature high-deductible Medicare Advantage plans that only cover medical costs once the member meets their high annual deductible, along with a special type of savings account with funds that are used to pay for health care costs before the deductible is met. MSA plans don’t include prescription drug coverage, but some plans cover dental, vision and long-term care services not covered by Original Medicare.

Enrollment and Eligibility for Medicare Advantage in Washington

Prior to enrolling in Medicare Advantage, seniors must first be enrolled in Original Medicare. Anyone who is eligible for Medicare Parts A and B is also eligible to enroll in Medicare Advantage. However, certain Medicare Advantage plans, such as SNPs, may have additional eligibility requirements.

Medicare Advantage has specific enrollment periods. One can only join a Medicare Advantage plan during the following periods:

  • Initial Coverage Election Period: This is the 7-month period during which everyone is eligible to enroll in a Medicare Advantage plan. The period spans from 3 months before the month of one's 65th birthday to 3 months after one's birthday month.
  • Annual Election Period (AEP): Also referred to as the Open Enrollment Period, the AEP runs from October 15-December 7 each year. During this period, anyone can enroll in Medicare Advantage for the first time or change to a new plan.
  • Medicare Advantage Open Enrollment Period: From January 1-March 31 each year, anyone who is already enrolled in Medicare Advantage can switch to a different plan, or disenroll and switch back to Original Medicare. This period is not open to anyone who is not currently enrolled in Medicare Advantage.
  • General Enrollment Period: In some circumstances, one can join Medicare Advantage between April 1-June 30. This enrollment period only applies to those who enrolled in Medicare Part B for the first time during Medicare's Open Enrollment Period (January 1-March 31).

Additionally, Medicare Advantage plan participants can change their plan outside of these enrollment periods under certain qualifying circumstances, such as moving to a new state.

Prescription Drug Coverage

In Washington, many Medicare Advantage plans provide coverage beyond what Original Medicare requires, including coverage for prescription drugs. Seniors enrolling in an HMO plan, PPO plan or SNP who want prescription drug coverage should ensure that the plan they choose has this coverage. Medicare Advantage plans that cover prescription drugs are required to follow the same rules as Medicare Part D and are often referred to as MA-PD plans. The state allows Medicare beneficiaries to add Part D prescription coverage to some Medicare Advantage plans, including PFFS and MSA plans.  In this case, the member generally pays two separate premiums, including one for their health care plan and one for prescription drug coverage.
