*This code is based on the original ICD-10 code above, validated against a reference standard (in this article).

The algorithm provides the STRIDE-defined serious fall injury outcome as well as the original fall-related health care outcome.

The code also unifies variable names to faciliate concatenation of Medicare Fee for Service and Medicare Advantage data

Validation of a Rule-Based ICD-10-CM Algorithm to Detect Fall Injuries in Medicare DataAbstractBackground. Diagnosis-code-based algorithms to identify fall injuries in Medicare data are useful for ascertaining outcomes in interventional and o
