Comparing Medicare plans in Washington
Medicare Part A is the foundation of the federal health insurance program, designed to cover the catastrophic costs of being hospitalized. If you are approaching age 65, navigating a qualifying disability, or managing your retirement planning in Washington, understanding how Part A operates is the first critical step in securing your healthcare future.
Whoever is reading this likely has a specific question in mind: What exactly does Medicare cover if I go to the hospital, and how much is it going to cost me? The direct answer is that Part A acts as your room-and-board coverage for inpatient medical care. It pays for your physical bed in the hospital, your inpatient meals, general nursing care, and the drugs administered to you while admitted. However, it operates under complex rules regarding “benefit periods,” observation status, and out-of-pocket cost-sharing that can catch the unprepared off guard.
This comprehensive guide serves as your authoritative pillar for understanding Medicare Part A in Washington state. We will explore exactly how eligibility works, what services are strictly covered (and explicitly excluded), the financial mechanics of deductibles and coinsurance, and how this foundational coverage integrates with the broader health insurance landscape.
To make an informed decision about your healthcare, you must first understand the architecture of the program. According to the Centers for Medicare & Medicaid Services (CMS), the Medicare program is divided into multiple “Parts,” each handling a different aspect of medical care.
When the Medicare program was established, it was built in two halves. Part A is designated as Hospital Insurance, while Part B is designated as Medical Insurance. Together, they form what the government and insurance professionals call “Original Medicare.”
Part A is designed strictly for facility-based care when you are formally admitted. If you are sleeping in a facility overnight for specialized, acute medical intervention, Part A is the financial mechanism that steps in to cover the institutional costs. It is not designed for preventive care, routine checkups, or outpatient procedures.
The easiest way to conceptually separate the two is to think of Part A as covering the building and the facility staff, while Part B covers the practitioners and outpatient services.
If you undergo a major surgery, Part A pays for your hospital room, your hospital bed, your inpatient meals, and the general nursing staff tending to you on the floor. Part B, conversely, pays the surgeon who performs the operation, the anesthesiologist who monitors your vitals, and the physician who visits your room for morning rounds. Because of this split, a single hospital stay generates bills under both Part A and Part B simultaneously. Understanding this division is crucial for anticipating your out-of-pocket exposure.
Medicare is a federal program, meaning the eligibility rules in Washington are identical to the rules in every other state. However, understanding how you qualify—and whether you will pay a premium for that qualification—requires looking at your personal work history and age.
Review the criteria below to determine if you are eligible for Medicare Part A and whether you qualify for premium-free coverage.
| Medicare Work Quarters | Part A Monthly Premium Status |
|---|---|
| 40 or more quarters (approx. 10 years) | $0 (Premium-Free) |
| 30 to 39 quarters | Prorated Monthly Premium |
| Fewer than 30 quarters | Full Monthly Premium |
The vast majority of Washington residents age into Medicare Part A when they turn 65. If you are already receiving Social Security retirement benefits or Railroad Retirement benefits when you turn 65, you will automatically be enrolled in Part A and Part B. Your coverage will generally begin on the first day of your birthday month. (If your birthday falls on the first day of the month, your coverage begins on the first day of the prior month).
You do not have to be 65 to receive Medicare Part A. If you are under 65 but have a qualifying disability, you become eligible for Part A after receiving Social Security Disability Insurance (SSDI) checks for 24 months. In this scenario, your Medicare Part A coverage automatically kicks in on your 25th month of disability.
There are two specific medical diagnoses that bypass the standard waiting periods:
It is vital to understand the precise boundaries of Part A. The coverage is robust, but it is highly specific and heavily regulated by CMS guidelines. Part A covers four primary categories of care: Inpatient Hospital Care, Skilled Nursing Facility (SNF) Care, Hospice Care, and limited Home Health Services.
This is the core benefit of Part A. If a doctor formally writes an order to admit you to a hospital as an inpatient, Part A covers the facility costs. This applies to acute care hospitals, critical access hospitals, inpatient rehabilitation facilities, and long-term care hospitals. It also includes inpatient care received in a psychiatric hospital, though Medicare limits psychiatric hospital coverage to a lifetime maximum of 190 days.
Under inpatient hospital care, Part A pays for:
Part A covers short-term, intensive rehabilitation at a Skilled Nursing Facility, but the criteria for this coverage are notoriously strict. A SNF provides high-level medical care administered by registered nurses and physical/occupational therapists—it is not a standard nursing home or assisted living facility.
To qualify for Part A coverage in a SNF, you must meet all of the following conditions:
If you meet these criteria, Part A covers your semi-private room, meals, skilled nursing care, physical and occupational therapy, speech-language pathology, medical social services, and medications given in the facility.
If you or a loved one faces a terminal illness, Part A provides comprehensive hospice benefits. To qualify, a hospice doctor and your regular doctor must certify that you are terminally ill, with a life expectancy of six months or less if the illness runs its normal course. Furthermore, you must sign a statement choosing hospice care instead of curative treatments for your terminal illness.
Hospice care is primarily provided in your home or a nursing facility where you already live, though short-term inpatient stays for pain and symptom management are covered.
Part A hospice benefits include:
Crucially, once you elect hospice under Part A, Medicare will no longer pay for treatments meant to cure the terminal illness, though you can stop hospice at any time and return to curative care if you choose.
While most outpatient and home-based care falls under Part B, Part A will cover specific home health services if you spend at least three consecutive days as an inpatient in a hospital or SNF, and you receive home health care within 14 days of discharge.
Coverage is strictly for part-time or intermittent skilled nursing care, physical therapy, speech-language pathology, or occupational therapy. You must be certified by a doctor as “homebound,” meaning leaving your home is a major effort and requires assistance. Part A does not cover 24-hour home care, meals delivered to your home, or homemaker services like cleaning and laundry.
If you require a blood transfusion as an inpatient, the hospital usually gets blood from a blood bank at no charge, and you won’t have to pay for it. However, if the hospital has to buy blood for you, Medicare Part A does not cover the cost of the first three pints of blood per calendar year. You are responsible for paying for those first three pints, unless you have a loved one donate blood to replace what you used, or you have supplemental insurance (like a Medigap plan) that covers the Part A blood deductible.
Understanding what is excluded from Part A is just as critical as understanding what is included. Many Washington seniors face shocking medical bills simply because they assumed “Medicare covers the hospital.”
This is one of the most common and dangerous pitfalls in Medicare Part A. You can be taken to a hospital emergency room, given a bed, dressed in a hospital gown, fed hospital food, and kept overnight for several days without ever being formally admitted. If your doctor designates you as being under “Observation Status,” you are technically an outpatient.
Because you are an outpatient, Medicare Part A will not pay for your room and board. Instead, the services will be billed under Medicare Part B, which has different cost-sharing rules and may not cover the expensive medications administered during your stay.
More importantly, because observation status does not count as a formal inpatient admission, time spent under observation does not count toward the 3-day inpatient requirement for Skilled Nursing Facility (SNF) coverage. You could spend four days in the hospital under observation, be transferred to a SNF for rehab, and find out Medicare Part A will pay absolutely nothing for the SNF stay.
Consumer Protection Note: Under the federal NOTICE Act, hospitals are required to provide you with a Medicare Outpatient Observation Notice (MOON) if you receive observation services as an outpatient for more than 24 hours. If you receive this notice, you should immediately ask your doctor if you can be formally admitted as an inpatient to protect your Part A benefits.
As mentioned earlier, Part A does not pay the doctors who treat you in the hospital. The surgeons, specialists, and even the physician reading your X-rays will bill their services to Medicare Part B. You will be responsible for the Part B deductible and the standard 20% coinsurance for those physician services, separate from whatever you pay for the Part A facility charges.
Medicare Part A is strictly for acute, medical care and rehabilitation. It does not cover long-term care or “custodial care.” Custodial care consists of help with activities of daily living (ADLs)—such as bathing, dressing, using the bathroom, and eating. If you develop a condition like dementia and require permanent placement in an assisted living facility, memory care unit, or nursing home, Medicare Part A will not cover those residential costs.
If you rely on Original Medicare without supplemental insurance, you carry significant financial liability. The cost structure of Part A is heavily dependent on a unique concept called the “Benefit Period.”
As outlined in the eligibility section, the vast majority of Washington beneficiaries do not pay a monthly premium for Part A. If you have 40 quarters of Medicare-taxed employment, your premium is $0. If you do not have 40 quarters, you must buy into Part A, and the monthly premium can exceed $500 per month depending on how many quarters you actually accrued.
Unlike typical commercial health insurance, the Part A deductible is not an annual deductible. It is tied to a “Benefit Period.”
A benefit period begins the day you are formally admitted as an inpatient to a hospital or SNF. The benefit period ends when you have been out of the hospital (or out of a SNF) and have not received any inpatient care for 60 consecutive days.
If you go to the hospital, pay your Part A deductible, get discharged, and are perfectly healthy for 65 days before breaking your hip and being readmitted, a new benefit period begins. You will have to pay the full Part A deductible a second time in the same calendar year. There is no limit to the number of benefit periods you can have in a year.
When you enter a hospital within a new benefit period, your out-of-pocket costs escalate based on the length of your stay.
| Length of Inpatient Hospital Stay | Your Out-of-Pocket Cost Structure |
|---|---|
| Days 1 through 60 | You pay the full Part A Deductible. ($0 coinsurance per day). |
| Days 61 through 90 | You pay a set daily coinsurance amount. |
| Days 91 and beyond | You pay a higher daily coinsurance using "Lifetime Reserve Days." |
| Beyond Lifetime Reserve Days | You pay 100% of all costs. |
(Note: The exact dollar amounts for the deductible and daily coinsurance are adjusted annually by CMS. Because these figures index upward each year, it is vital to check the current year’s Medicare handbook for the exact dollar figure. However, the structural mechanism—a flat deductible for the first 60 days, followed by steep daily coinsurance penalties—remains constant.)
The structure for a Skilled Nursing Facility (SNF) operates on a different timeline within the benefit period:
If your hospital stay exceeds 90 days in a single benefit period, you begin tapping into your “Lifetime Reserve Days.” Medicare grants you exactly 60 of these days for your entire life. When you use a lifetime reserve day, you pay a significant daily coinsurance, and Medicare pays the rest.
Once those 60 days are used up, they are gone forever. If you exhaust your lifetime reserve days and remain in the hospital past day 90 of a benefit period, Medicare Part A stops paying, and you become fully responsible for all hospital facility charges.
Understanding when to activate your Part A benefits is critical, particularly because of the severe tax penalties associated with mishandling the transition from employer coverage.
If you are receiving Social Security retirement benefits at least four months before you turn 65, you do not need to do anything. The government will automatically enroll you in Medicare Part A and Part B, and your red, white, and blue Medicare card will arrive in the mail a few months before your 65th birthday.
If you are not receiving Social Security (because you are delaying your retirement benefits to maximize your monthly payout), you must actively apply for Medicare through the Social Security Administration.
Your Initial Enrollment Period is a 7-month window that begins three months before the month you turn 65, includes your birthday month, and extends three months after your birthday month. If you want your coverage to begin exactly when you turn 65, you should enroll during the first three months of this window.
If you miss your IEP and do not qualify for a special exception, you must wait for the General Enrollment Period, which runs from January 1 to March 31 every year. Coverage will begin the month after you enroll. Missing your initial window can result in late enrollment penalties, though this primarily impacts Part B, or Part A only if you do not qualify for premium-free Part A.
If you are 65 but still working and covered by an employer’s group health plan (or covered by your working spouse’s plan), you may choose to delay Medicare enrollment. When that group coverage ends, or when the employment ends, you are granted a Special Enrollment Period lasting 8 months to enroll in Medicare without penalty.
This is a critical rule for Washington professionals who utilize High Deductible Health Plans (HDHPs) with a Health Savings Account (HSA). You cannot contribute to an HSA if you are enrolled in Medicare Part A.
Under IRS rules, contributing to an HSA while having any part of Medicare triggers a tax penalty. Furthermore, when you finally apply for Part A after age 65, the government retroactively activates your Part A coverage by up to 6 months. Therefore, you must stop all contributions to your HSA at least 6 months before you intend to apply for Medicare Part A to avoid retroactive tax penalties.
Part A does not operate in a vacuum. Most Washington residents combine Part A with other forms of insurance to manage the out-of-pocket risks.
In Washington state, you have the option to receive your Part A (and Part B) benefits through a private health insurance company rather than directly from the federal government. This is called Medicare Advantage (Part C).
By law, Medicare Advantage plans must cover everything that Original Medicare Part A covers. However, they structure the costs differently. Instead of the complex “Benefit Period” deductibles and lifetime reserve days, an MA plan might charge a flat daily copay for the first 5 or 6 days of a hospital stay, and $0 thereafter. MA plans also include an annual Maximum Out-of-Pocket (MOOP) limit, providing a hard cap on your financial liability—a safeguard Original Medicare does not offer.
In Washington, major carriers like UnitedHealthcare, Kaiser Permanente, Providence Medicare Advantage Plans, and Regence BlueShield administer these plans. When you enroll in a plan like the AARP Medicare Advantage from UHC WA-0001 (PPO) or a Kaiser HMO, you still possess Medicare Part A, but UnitedHealthcare or Kaiser dictates the network, authorizes the admissions, and manages the billing.
If you choose to stay on Original Medicare rather than moving to a Medicare Advantage plan, you remain fully exposed to the Part A deductible per benefit period and the 20% coinsurance of Part B.
To protect against this, many seniors purchase a Medicare Supplement (Medigap) policy. Private carriers sell these standardized policies to pay the costs that Original Medicare leaves behind. For example, a Medigap Plan G will pay the entire Part A hospital deductible for you, regardless of how many benefit periods you trigger in a year. It will also cover the daily coinsurance for days 61-150 in the hospital, and grant you an additional 365 lifetime reserve days after Medicare’s coverage is exhausted.
If you are 65 and still working for a company with 20 or more employees, your employer group health plan pays first, and Medicare pays second. Because Part A is premium-free for most people, many actively working seniors choose to enroll in Part A at 65 anyway, letting it act as secondary coverage to pick up inpatient costs their employer plan might leave behind (provided they are not contributing to an HSA). If the employer has fewer than 20 employees, Medicare pays first, making enrollment at 65 virtually mandatory to avoid massive coverage gaps.
For individuals with limited income and resources, Washington state offers Apple Health (the state’s Medicaid program). If you qualify for both Medicare and Medicaid (known as being “dual-eligible”), Apple Health steps in to act as secondary insurance. Depending on your level of qualification through the Medicare Savings Programs (MSP), the state of Washington may pay your Part A premiums (if you don’t have 40 quarters), your deductibles, and your coinsurance, effectively insulating you from inpatient hospital costs.
Washington state has a highly robust, competitive Medicare market. According to recent data, there are 124 distinct Medicare Advantage plans available across the state, though availability is strictly tied to the specific county you live in.
Because Washington encompasses densely populated urban centers like Seattle and Tacoma, alongside vast rural areas east of the Cascades, the network dynamics for your Part A care can vary wildly.
Prominent carriers operating in the Washington market include:
If you opt for Original Medicare and a Medigap plan, you can use your Part A benefits at any hospital in the United States that accepts Medicare. If you opt for a Medicare Advantage plan through one of the carriers listed above, you will need to ensure your preferred local hospital (e.g., UW Medical Center, Providence Sacred Heart, or MultiCare) is in-network with that specific plan to avoid paying out-of-network penalties.
Understanding Part A is an exercise in risk management. The coverage is exceptional for true catastrophic events, but the structural design leaves significant financial exposure for chronic issues or spaced-out hospitalizations.
