About the 5A0 Code Range
These procedures use means outside the body to take over part of a heart, circulation, or breathing function. They include assistance with ventilation, oxygenation, and filtration.
The fourth character identifies the body system as Cardiac, Circulatory, or Respiratory. The fifth records duration, such as intermittent, continuous, intraoperative, or a consecutive-hour range. The sixth names the function, such as filtration, oxygenation, or ventilation. The seventh adds a detail such as a balloon pump, an airway pressure type, or a filter type; it can also be No Qualifier.
FY 2027 changes: The FY 2027 ICD-10-PCS update, effective October 1, 2026, added 5A0221E and 5A0527D.
