Number of Medicare fee-for-service beneficiaries with breast cancer


Number of Medicare fee-for-service beneficiaries


The data value for this metric is the numerator divided by the denominator.

Medicare fee-for-service (FFS) beneficiaries limited to those who (a) have no months of HMO enrollment and (b) have both Part A and Part B for whatever portion of the year that they are covered by FFS Medicare (i.e., they have no months of A-only or B-only coverage).

Beneficiary age group (< 65 and 65+ ) was determined using the age of the individual at the end of the reference year or the individual's age at the time of death.

Of this population, beneficiaries with CCW CNCRBRST chronic condition flag values of "1" or "3'" were determined to have had breast cancer.
