MDCR_BUYIN_01
This variable is the monthly Medicare Part A and/or Part B entitlement indicator. There are separate variables for each of the 12 months during the year.
| Code | Code value |
|---|---|
| 0 | Not entitled to Medicare |
| 1 | Part A only |
| 2 | Part B only |
| 3 | Part A and Part B |
| A | Part A state buy-in |
| B | Part B state buy-in |
| C | Part A and Part B state buy-in |
| Null/missing | Not Medicare enrolled for the month |
CCW obtains this directly from the MBSF BENE_MDCR_ENTLMT_BUYIN_IND_01–12 variables.
This variable indicates whether the beneficiary was entitled to Medicare Part A, Part B, or both for a given month. It also indicates whether the beneficiary’s state of residence paid his/her monthly premium for Part B coverage (and Part A if necessary). State Medicaid programs can pay those premiums for certain dual eligibles; this action is “buying in” and so this variable is the “buy-in code.”
