The patient presented with fever/chills, weakness and worsening left lower extremity pain. He was diagnosed with sepsis and acute arterial insufficiency of the left lower extremity with plan for surgical amputation after resolution of the sepsis. The patient’s clinical status was deemed unstable for surgical amputation; therefore, cryoamputation was performed. The leg was inserted into a cooler and surrounded by dry ice; the cooler was then taped and sealed to prevent any cold air escape. How should cryoamputation of the left leg be coded in ICD-10-PCS?
It is not necessary to report cryoamputation. However, if facilities wish to report this procedure, assign the following procedure code:
6A4Z0ZZ Hypothermia, single, for the cryoamputation of the left leg
Do not assign a Detachment procedure code. Cryoamputation does not meet the definition of the root operation Detachment since no part of the leg is removed.
