Risk Adjustment of ICD-10-CM Coded Potential Inpatient Complications Using Administrative Data.

Objective: To risk-adjust the Potential Inpatient Complication (PIC) measure set and propose a method to identify large deviations between observed and expected PIC counts.

Data Sources: Acute inpatient stays from the Premier Healthcare Database from January 1, 2019 to December 31, 2021.

Study Design: In 2014, the PIC list was developed to identify a broader set of potential complications that can occur as a result of care decisions.
