Medicare part B is administered by the Centers for Medicare and Medicaid Services (CMS) which is part of the Department of Health and Human Services (HHS). CMS routinely releases advisories describing coverage criteria and changes. These advisories are called National Coverage Determinations (NCD). They describe limitations of the particular coverage. There are also similar local advisories issued by the regional Medicare contractor called Local Coverage Determinations (LCD).

Enrollment for Part B can be started during a 7-month period beginning 3 months before age 65. If an eligible participant decides not to enroll in Part B and is without other coverage, but changes their mind later, enrollment can be made during the annual General Enrollment Period, January 1 through March 31. Part B benefits will not be effective until July 1 of that year. A late enrollment penalty of 10% of the current Part B premium may be required for each 12-month period the insured could have had Part B coverage, but did not take it.
