A beneficiary who was previously entered to Medicare part a but not yet part B is

probably lacking the eligibility requirements.

Explanation:

Remember, the Medicare insurance program covers the cost of medical services and supplies needed to treat a patient.

It is generally known that to qualify for a Medicare PART B program certain requirements such as the following needs to be met with exception for a few categories of persons:

you can qualify for Medicare Part B by meeting the following requirements:

- must be 65 years or older.

- must be a U.S. citizen, or a permanent resident

- must be lawfully residing in the U.S for at least five continuous years.

Although individual's below 65 may automatically quality for Medicare part A and part B if they have a disability.

However, the main reasons an individual may not have enrolled for Medicare part B even though they had entered part B is due to the premium attached to Medicare part B.
