About 5A1935Z

5A1935Z is the ICD-10-PCS code for a performance procedure on the respiratory using a less than 24 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 less than 96 consecutive hours, the ICD-9-CM procedure titles it maps to (96.70 and 96.71).

The same procedure with a different approach is coded 5A1945Z (24-96 consecutive hours) and 5A1955Z (greater than 96 consecutive hours).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 208 (Respiratory System Diagnosis with Ventilator Support <=96 Hours), under the surgical category “Respiratory System Diagnosis with Ventilator Support”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
