This variable is the Part D contract number for the beneficiary’s Part D plan for a given month (February). CMS assigns an identifier to each contract that a Part D plan has with CMS.
The first character of the contract ID is a letter that indicates the type of plan. If the beneficiary did not have a Part D plan for a given month, this variable will have a value of N, 0, or be null/missing for that month. If the beneficiary changed plans during the year, the value indicates the final, reconciled contract number. For 2006–2012, this variable was always encrypted to comply with CMS privacy rules.
There are 12 monthly variables — where the 01 through 12 at the end of the variable name correspond with the month (e.g., 01 is January and 12 is December).
You need to know both the Part D contract number and plan benefit package (PTD_PBP_ID_XX) to identify the specific plan in which a beneficiary was enrolled.
