What Is A Part A Benefit Period?

A benefit period begins when a beneficiary is admitted for inpatient care. The benefit period ends when related inpatient care has not been received for 60 days. A new benefit period starts if the beneficiary is admitted as an inpatient after the previous benefit period ends. For each benefit period, the beneficiary will have to pay the inpatient hospital deductible ($1,484 in 2021).⁴

Days 1-60: $0 coinsuranceCoinsurance is a percentage of the total you are required to pay for a medical service. for each benefit period.
Days 61-90: $371 coinsurance per day (2021 rate) of each benefit period.
Days 91 and beyond: $742 coinsurance per day (2021 rate)

Note: After 90 days of hospitalization a beneficiary begins using their 60 lifetime reserve days. For a complete definition of how lifetime reserve days work, see What are Medicare Lifetime Reserve Days.

Skilled Nursing Facility Care

When a beneficiary is hospitalized and treated but needs skilled care to convalesce, their doctor may have them transferred to a skilled nursing facility (SNF). Medicare Part A coverage in an SNF is different than in a hospital setting. The costs are as follows:

Days 1–20: Beneficiary pays $0 for each benefit period.
Days 21–100: Beneficiary pays $185.50 coinsurance per day of each benefit period.
Days 101 and beyond: Beneficiary pays all costs.

For the first 20 days of a beneficiary’s care in a skilled nursing facility, they pay nothing after their deductible has been met. From day 21 until day 100 of their skilled nursing facility benefit period, they pay a $185.50 coinsurance each day. After that, they are responsible for all further costs for their skilled nursing facility care.⁶

Home Health Care

If a beneficiary’s doctor determines that home healthcare is needed after hospitalization, they will create a plan to provide it. Medicare covers the following for home healthcare services:⁷

Skilled nursing care on a part-time or intermittent basis.

Physical therapy, speech-language therapy, and occupational therapy
Counseling for social and emotional concerns related to the beneficiary’s illness.
Certain medical supplies like wound dressings, but not prescription drugs or biologicals.
Medical equipment such as a wheelchair or walker.

Medicare covers these home healthcare services as long as the beneficiary’s doctor orders the services. The skilled nursing and home health aide services can only be covered part-time or intermittently. This means that there are limitations on how many hours a beneficiary can receive skilled nursing and home health aide services.⁷
