About 5A0955A

5A0955A is the ICD-10-PCS code for a assistance procedure on the respiratory using a greater than 96 consecutive hours approach with ventilation (qualifier: high flow/velocity cannula). In ICD-10-PCS, assistance means taking over a portion of a physiological function by extracorporeal means.

The same procedure with a different approach is coded 5A0935A (less than 24 consecutive hours) and 5A0945A (24-96 consecutive hours).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2021, effective October 1, 2020.
