ICD-10-PCS Section: 6 - Extracorporeal or Systemic Therapies

Extracorporeal or Systemic Therapies

The seven characters in the extracorporeal therapies section have the following meaning:

  • Character 1 = Section
  • Character 2 = Physiological System
  • Character 3 = Root Operation
  • Character 4 = Body System
  • Character 5 = Duration
  • Character 6 = Qualifier
  • Character 7 = Qualifier

In extracorporeal therapy, equipment outside the body is used for a therapeutic purpose that does not involve the assistance or performance of a physiological function. Extracorporeal therapy procedure codes have a first character value of "6". The second character value for body system is physiological systems. There are ten root operations in the extracorporeal therapy section, as defined below.

  • Phototherapy: Extracorporeal treatment by light rays
  • Atmospheric Control: Extracorporeal control of atmospheric pressure and composition
  • Decompression: Extracorporeal elimination of undissolved gas from body fluids
  • Electromagnetic Therapy: Extracorporeal treatment by electromagnetic rays
  • Hyperthermia: Extracorporeal raising of body temperature
  • Hypothermia: Extracorporeal lowering of body temperature
  • Pheresis: Extracorporeal separation of blood products
  • Ultrasound Therapy: Extracorporeal treatment by ultrasound
  • Ultraviolet light Therapy: Extracorporeal treatment by ultraviolet light
  • Shock Wave Therapy: Extracorporeal treatment by shock waves

The fourth character specifies the body system on which the extracorporeal therapy is performed (e.g., skin, circulatory). The fifth character specifies the duration of the procedure (e.g., single or intermittent). The sixth character is not specified for extracorporeal therapies, and always has the value No Qualifier. The seventh character qualifier is used in the root operation Pheresis to specify the blood component on which pheresis is performed.
