Hospital-Acquired Complications (HACs) List - Specifications - Version 3.1 (12th edn)
The HACs are identified using a combination of ICD-10-AM codes to identify the diagnosis and the condition onset flag (METeOR identifier: 354816) to indicate that the diagnosis occurred during the episode of admitted patient care.
Some HACs also require other codes to define the complication such as procedure and external cause codes.
