SAS Name
HIP_FRACTURE_EVER
This variable shows the date when the beneficiary first met the criteria for the Chronic Conditions Warehouse (CCW) hip/pelvic fracture indicator. The variable will be blank for beneficiaries that have never had the condition.
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 First Occurrence of Hip/Pelvic Fracture variable in the CC27 version includes fewer DX codes and a reduced claim requirement.
The earliest possible date for this variable is January 1, 2016, since the algorithm for this condition requires ICD-10 diagnosis codes within the specified lookback period. If the beneficiary became eligible for Medicare after that, the earliest possible date will be some time after his/her coverage start date (i.e., the COVSTART variable in the Master Beneficiary Summary File [MBSF]).
