ICD-10-PCS 5A1 Extracorporeal or Systemic Assistance and Performance: Physiological Systems Performance

The ICD-10-PCS root operation Performance (code prefix 5A1) refers to providing extracorporeal or systemic assistance to physiological systems without directly altering the body parts themselves. This procedure supports or maintains vital bodily functions using mechanical or manual means.

Within the classification of Extracorporeal or Systemic Assistance and Performance, these codes capture interventions such as the Performance of Cardiac Output—whether Single, Manual (code 5A12012) or Continuous, Automated (code 5A1221J)—and account for cardiac pacing delivered intermittently or continuously. The root operation also includes various forms of Extracorporeal Oxygenation, distinguishing between Central and Peripheral Veno-arterial or Veno-venous approaches, with intraoperative options. Additionally, different durations of Respiratory Ventilation are coded, ranging from nonmechanical single episodes to extended ventilation beyond 96 hours. Filtration procedures for biliary and urinary systems, delivered intermittently or continuously, also fall under this operation, highlighting its broad role in sustaining life functions without bodily alteration.
