About 5A1955Z
5A1955Z is the ICD-10-PCS code for a performance procedure on the respiratory using a greater than 96 consecutive hours approach with ventilation. In ICD-10-PCS, performance means completely taking over a physiological function by extracorporeal means.
In plain terms, this corresponds to continuous invasive mechanical ventilation of unspecified duration and continuous invasive mechanical ventilation for 96 consecutive hours or more, the ICD-9-CM procedure titles it maps to (96.70 and 96.72).
The same procedure with a different approach is coded 5A1935Z (less than 24 consecutive hours) and 5A1945Z (24-96 consecutive hours).
It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 003 (ECMO or Tracheostomy with MV >96 Hours or Principal Diagnosis Except Face, Mouth and Neck with Major O.R. Procedures), DRG 004 (Tracheostomy with MV >96 Hours or Principal Diagnosis Except Face, Mouth and Neck without Major O.R. Procedures), DRG 207 (Respiratory System Diagnosis with Ventilator Support >96 Hours), DRG 870 (Septicemia or Severe Sepsis with MV >96 Hours) and DRG 927 (Extensive Burns or Full Thickness Burns with MV >96 Hours with Skin Graft), under the surgical categories “ECMO or Tracheostomy with MV >96 Hours or Principal Diagnosis Except Face, Mouth and Neck”, “Tracheostomy with MV >96 Hours or Principal Diagnosis Except Face, Mouth and Neck without Major O.R. Procedures”, “Respiratory System Diagnosis with Ventilator Support” and 2 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
