Release Notes:
Data Element
Version 2015A1

Data Element Name: Initial Patient Population Size – Non-Medicare Only
Collected For: HBIPS, PC, Transmission, Patient Population Data File
Definition:Indicates the number of episode of care (EOC) records identified for a hospital with Medicare NOT listed as a payment source prior to the application of data integrity filters, measure exclusions, and/or sampling methodology for the specified time period.

The data element is based on the hospital's initial identification of non-Medicare EOC records for a measure set, stratum, or sub-population. This initial data pull utilizes administrative data such as ICD-9-CM diagnosis and procedure codes, admission date, and birthdate.

For the discharge measures (eg. HBIPS-1, 4, PC-01), refer to the Initial Patient Population discussion in the Measure Information section of this manual for more information.

For the HBIPS event measures (HBIPS-2 and 3), the Initial Patient Population Size – Non-Medicare Only is equal to those EOC records in the census data identified as not having Medicare listed as a payment source. The HBIPS census data are calculated by (Psychiatric Inpatient Day-Non-Medicare Only - Total Leave Days-Non-Medicare Only). Initial Patient Population Size – Non-Medicare Only is not derived from those cases that pass through the Initial Patient Population algorithm.

Note:
If the hospital’s data has been sampled, this field contains the population from which the sample was originally drawn, NOT the sample size.
