Monthly values for the ninth of up to 16 managed care plan identification numbers under which the eligible beneficiary is enrolled. There are separate variables for each of the 12 months during the year. The last two digits of this variable indicate the month.
States may use their own identifier or the national health plan identifier.
For each month, there are up to 16 managed care plan IDs; the sequence (1st-16th plan ID) is indicated by the 3rd and 4th digits from the right (e.g., MC_PLAN_ID_05_MM) is the monthly variable string for the 5th MC plan ID.
The monthly MC_PLAN_ID_09_MM corresponds to the managed care plan type code (MC_PLAN_TYPE_CD_09_MM) for the same month.
