Current reason for Medicare entitlement.
This variable indicates how the beneficiary currently qualifies for Medicare. The current reason for entitlement can differ from the original reason that a beneficiary qualified for Medicare (see the OREC variable). CMS obtains this information from the Social Security Administration (SSA) and Railroad Retirement Board (RRB) record systems.
