ICD-10-PCS Body System: ICD-10-PCS Body System 6A - Physiological Systems

The ICD-10-PCS root operation Physiological Systems (Character 6A) involves extracorporeal or systemic therapies designed to alter or manage physiological functions outside the body. This category includes various treatments that regulate body systems through non-invasive means.

Within the Extracorporeal or Systemic Therapies classification, physiological systems codes cover a wide range of procedures such as Atmospheric Control (code 6A0) to manage pressure and gas composition, and Decompression (code 6A1) which removes undissolved gases from body fluids. Other notable examples include therapeutic modalities like Electromagnetic Therapy (6A2), Hyperthermia (6A3), and Hypothermia (6A4) that adjust body temperature externally. Blood product separation by Pheresis (6A5) and various light or wave therapies such as Phototherapy (6A6), Ultrasound Therapy (6A7), and Shock Wave Therapy (6A9) are also included, highlighting the diverse methods of extracorporeal treatment. These codes precisely document systemic interventions aiming to modify physiological conditions without direct surgical manipulation.
