Comments

Source: Historically, most Medicare managed care plans have been health maintenance organizations (HMOs), hence the name of the variable.

This variable indicates whether the beneficiary was enrolled in a Medicare Advantage (MA) plan during a given month.

The 01 through 12 at the end of the variable name correspond with the month (i.e., 01 is January and 12 is December).
