Comments

CCW creates this variable using the MBSF. We consider the beneficiary to have Medicare Advantage (also referred to as health maintenance organization [HMO]) coverage if the beneficiary had Medicare enrollment for the month, and the monthly beneficiary HMO (Medicare Advantage) indicator code was a value other than '0' (Not a member of an HMO) or '4' (Fee-for-service participant in case or disease management demonstration project) (i.e., BENE_HMO_IND_MM NOT IN ('0' '4').

Values: 0-12, or null/missing (if no Medicare enrollment)
