Indicates the number of episode of care (EOC) records identified for a hospital with Medicare listed as a payment source for a hospital to perform data abstraction on. This count is after the appropriate sampling methodology, if any, has been applied for the specific time period.

Notes for discharge measures (eg. HBIPS-1, 4, PC-01):

If the hospital is sampling the discharge measures, then the Sample Size Medicare Only should be equal or less than the Initial Patient Population Size Medicare Only for the set, stratum, or sub-population.
If the hospital is not sampling the discharge measures, then the Sample Size Medicare Only will equal the Initial Patient Population Size Medicare Only for the set, stratum, or sub-population.

Notes for HBIPS event measures (HBIPS-2 and 3):

Hospitals may not sample the HBIPS event measures. For these two measures, the Sample Size Medicare Only equals the Initial Patient Population Size Medicare Only for the set, stratum, or sub-population.
