Heart Failure and Non-Ischemic Heart Disease End-of-Year Indicator

SAS Name
HF

This variable indicates whether a beneficiary met the Chronic Conditions Warehouse (CCW) criteria for heart failure (HF) and non-ischemic heart disease as of the end of the calendar year.

Comments

The CCW’s chronic condition indicator variables require beneficiaries to satisfy both claims criteria (a minimum number/type of claims that have the proper diagnosis codes and occurred within a specified time period) and coverage criteria (FFS Part A and Part B coverage during the entire specified time period).


For heart failure and non-ischemic heart disease, beneficiaries must have at least one inpatient, skilled nursing facility (SNF), or home health claim, or two Part B (institutional or non-institutional) claims that are at least one day apart, with a heart failure and non-ischemic heart disease code in any position during the two-year reference period.

ResDAC Comments

From CY 2017 to CY 2021, the MBSF: Chronic Conditions segment also has a previous (CC27) version. The algorithm used to create the Heart Failure and Non-Ischemic Heart Disease End-of-Year Indicator variable in the CC27 version includes fewer DX codes and a reduced claim requirement.
