Why do researchers request this file?
- Conduct research that identifies LIS beneficiaries and studies the effects of Part D auto-assignment, and reassignment policies.
Special considerations
- There is at least one record for every beneficiary enrolled in Part D during the year; there may be multiple records if more than one plan was elected during the year.
