About 4A030BF

4A030BF is the ICD-10-PCS code for a measurement procedure on the arterial using an open approach with pressure (qualifier: other thoracic). In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.

In plain terms, this corresponds to intravascular pressure measurement of intrathoracic arteries, the ICD-9-CM procedure title it maps to (00.67).

The same procedure with a different approach is coded 4A033BF (percutaneous).

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

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