Number of Part D Enrollees

Number of Patients with Part D Enrollment

The following tables list the number of persons appearing in the SEER-Medicare data who are enrolled in Medicare Part D as well as the total number of patients who were eligible to enroll according to the PEDSF file. The tables were generated separately for patients not enrolled in Managed Care and for those enrolled in Managed Care only. The results were produced for three calendar years: year of diagnosis, year before diagnosis, and year after diagnosis; for all patients and by cancer site for patients with a first primary cancer. The results are further broken out by a patient's year of diagnosis, allowing for the identification of patients diagnosed during a specific year who were also enrolled in Medicare Part D during the three calendar year time periods.
