About the 6AB Code Range

The ICD-10-PCS root operation Perfusion (6AB) refers to the process of delivering a physiological fluid, such as blood or a blood substitute, to an extracorporeal or systemic site. This operation is used to maintain or restore circulation or function through artificial means, most commonly related to organ preservation or treatment support.

Within the Extracorporeal or Systemic Therapies section, Perfusion specifically applies to physiological systems, often involving donor organs. Examples include perfusion of a donor Circulatory system organ (6AB50BZ), Respiratory system organ (6ABB0BZ), Hepatobiliary system and pancreas donor organ (6ABF0BZ), and Urinary system donor organ (6ABT0BZ). These codes capture the targeted delivery of fluids to sustain the viability of donor organs prior to transplantation.

Accurate coding of this ICD-10-PCS Perfusion operation is essential for documenting the specific organ system treated and the extracorporeal method applied, supporting clear communication of therapeutic interventions in organ preservation and systemic management.
