Medicare is a federal health insurance program for people age 65 or older, people of all ages with disabilities, and people with End-Stage Renal Disease (ESRD) or ALS — Lou Gehing’s Disease.

Who is Eligible for Medicare?

People who are at least 65 years of age

  • Worked 10 or more years in Medicare-covered employment, and paid ( or spouse paid) Social Security for at least 40 quarters.
  • Are citizens or permanent residents of the United States.
  • Have been diagnosed with ESRD or ALS.

People who are not yet 65 years of age

  • After 24 months of Social Security Disability Insurance income.
  • Have been diagnosed with ESRD or ALS.

Original Medicare Plan

People with Original Medicare are called beneficiaries. Beneficiaries can go to any doctor, supplier, hospital, or other facility that accepts Medicare and is accepting new Medicare beneficiaries.

Beneficiaries with Original Medicare are responsible for a deductible and coinsurance for most covered services. The deductible is the amount a beneficiary must pay before Medicare begins to pay for services and supplies covered under the Original Medicare program. Once the deductible is met, the beneficiary is responsible for a coinsurance- it is an 80% Medicare / 20% beneficiary split. 

There are no maximum out-of-pocket limits for Original Medicare.

To lower and contain potential medical costs, beneficiaries may choose to purchase supplemental coverage in the form of either:

  * Medigap and a stand-alone Prescription Drug Plan (Part D)

 * Medicare Advantage plan, usually with Part D included

Medicare beneficiaries are required to have Prescription Drug Coverage. If you do not have coverage at least as good as Medicare Part D from an employer, union, or military, you will have to pay a penalty for each month you don’t have Part D coverage.

Services Typically Not Covered Under Original Medicare

The Four Parts of Medicare

Medicare is made up of four parts. The following information is to help you understand each part of Medicare.

Inpatient Hospital Insurance
Medicare PART A

Eligible individuals are automatically enrolled in Part A with no premium. Others apply to the program when they are eligible or pay a monthly premium if they have worked less than 40 quarters (or 10 years) in their lifetime.


  • Helps cover inpatient care in hospitals (includes critical access hospitals, inpatient rehabilitation facilities and long-term care hospitals).
  • Helps cover skilled nursing facilities (not custodial or long-term care), hospice and home healthcare services.

Does not cover

Physician services in the hospital, personal care items, private rooms (unless medically necessary), phone, television, and custodial care, such as assistance with eating, bathing, and getting dressed.


There are some limitations of the number of hospital days covered for inpatient hospital coverage. Days 1-60 in a hospital stay are covered after a deductible is met. Days 61-90 are covered with a copay charge per day. Day 91 and after use up to 60 lifetime reserve days with a copay charged per day. Once the reserve days are used, an additional 365 days can be accessed at a $0 copay per day.

Outpatient/Physician Insurance
Medicare PART B

To obtain Part B, an eligible individual must enroll at their Social Security office during a specific period (usually 90 days before your birth month, the month of, or up to 90 days after). There are special enrollment periods in addition to turning 65.

Part B only covers care for eyes, teeth, or hearing when medically necessary. No coverage for custodial care, such as assistance with eating, bathing, and getting dressed. No coverage outside the United States.

Medicare Advantage Plans
Medicare PART C

Sometimes called an “All in One” plan, Medicare Advantage plans are a way to get Medicare benefits through private companies approved by and under contract with Medicare.


  • Includes Part A, Part B, and usually additional benefits Medicare doesn’t cover (such as fitness benefits, chiropractic care, or vision and hearing benefits).
  • Often includes Part D Coverage.
  • Benefits that go beyond Original Medicare such as out-of-pocket maximums.
  • Preventive Dental Included
  • See our Medicare Advantage page for more details.

Does not cover

Hospice Care (still provided by Original Medicare). It’s important to review each plan carefully tosee what it does and does not cover.


Coverage options vary by plan and plan type. It’s important to review options carefully. Medicare Advantage plans do not have the same network as Original Medicare.

Prescription Drug Coverage
Medicare PART D

Part D is voluntary and is designed to supplement Part A and B coverage that does not include Part D benefits. Stand- alone Part D plans are plans that specifically help cover and lower prescription drug costs. Stand-alone Part D plans are available through private companies that contract with Medicare. If an individual does not have creditable coverage (coverage equal to Original Medicare) they are subject to a penalty for each month they are not enrolled.


  • Each Part D plan covers a minimum of one drug in each therapeutic class as mandated by Medicare.
  • Each drug is assigned a Tier level and copay or coinsurance.
  •   Each Part D plan utilizes a network of pharmacies.

Does not cover

Drugs not on the Medicare formulary and certain drugs that are covered under Part B.


Coverage options vary by plan and plan type. It is important to review options carefully as each plan determines tier placement of drugs and network of pharmacies.

Medicare Insurance FAQ

Many people use Medicare supplemental insurance to augment their current insurance plans. Medicare supplemental insurance is important because it provides individuals with a way to purchase their necessary drugs and it gives them protection if they ever enter the hospital for an extended period of time. Though there are a huge number of people who use Medicare as their only means of funding medical coverage, those individuals with employer-provided health care plans and personal health care plans are able to use Medicare for this supplemental element. It can act as a powerful policy for covering any over the top costs that typical insurance policies might miss.

Medicare Part A Hospital: Coverage associated with any hospital or surgical facilities.

Medicare Part A is the hospital insurance portion of Original Medicare. Hospitalizations make up some of the largest costs associated with medical care. The cost of care while hospitalized can add up to large dollar amounts in a matter of days.

Medicare Part A is generally "free" or 'pre-paid' if the work history requirements have been met.

 The Medicare Part A deductible in 2022 is $1,556 and is applicable to days 1-60. Once the deductible is paid, days 61-90 are covered with a copay of $389 per day. Day 91 and after use up to 60 lifetime reserve days at a copay of $778 copay per day. Once the reserve days are used, an additional 365 days can be accessed at a $0 copay per day. Providers must accept Medicare and be accepting new patients.

Medicare Part B Medical: Coverage associated with physician office visits, testing, a select number of prescription drugs, and DME (durable medical equipment).

Medicare Part B is the medical portion of Original Medicare, with the focus area of care on physician office visits. Physician office visits to primary care and specialists, x-rays, labs, scans, and chemotherapy are a few areas covered under Part B. Coverage also extends to DME (Durable Medical Equipment). DME includes wheelchairs, canes, walkers, oxygen supplies and C-pap equipment.

As previously stated, the average cost of Part B for 2022 is $170.10 per month, per person. This cost can be higher depending on earned income.

Under Original Medicare Part B, a deductible of $233 is required and a 20% coinsurance is owed for services completed after the deductible is met.  

Medicare Part C: Referred to as Medicare Advantage plans

Medicare Part C a.k.a. Medicare Advantage plans are plan benefits offered by private insurance companies. Medicare Advantage plans are designed to lower the out-of-pocket costs associated with Original Medicare; and in some cases, offer additional services not provided by Original Medicare.

With Part C a.k.a. Medicare Advantage, insurance plans are purchased with private insurance companies that have designed benefits that meet or exceed Medicare minimum guidelines. The benefits include, but are not limited to, prescription drugs, hospital services, physician services, mental health services, preventive dental, vision, and hearing.

Monthly insurance premiums for Medicare Advantage plans range depending on location. In Oregon, plan premiums generally range between $0 and $150 per month. The Medicare Part B premium must also be paid.  

Medicare Part D: Prescription Drug benefits

Medicare Part D benefits were created in 2006. Part D benefits exist to provide coverage and lower costs for Medicare approved prescription drugs; generally, those prescription drugs ordered at a retail or mail order pharmacy.

Part D benefits are required (or a penalty will be incurred) in the form of either a stand-alone Part D plan or as an embedded benefit in a Medicare Advantage plan. There are exceptions to this rule; including, but not limited to, access to Veteran benefits.

Medicare Supplement Plans a.k.a. Medigap plans

Medicare supplement plans are often referred to as Medigap plans. Medigap plans are designed to pay as secondary to Original Medicare and supplement the deductibles and coinsurance of Original Medicare benefits. Medigap plans available to new enrollees after 2020 are Plan A, B, D, G, HDG, K, L, M, N. Plan C, F, and HDF are only available if eligible for Medicare Part A & B prior to January 2020.

Medigap plans do not include Part D benefits and therefore require the purchase of a separate stand-alone Part D plan. Medigap plans do cover the select prescription drugs covered by Medicare Part B.

Medigap plan premiums in Washington range depending on zip code, tobacco status, and plan selected.
