About 4A033BC

4A033BC is the ICD-10-PCS code for a measurement procedure on the arterial using a percutaneous approach with pressure (qualifier: coronary). 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 coronary arteries, the ICD-9-CM procedure title it maps to (00.59).

The same procedure with a different approach is coded 4A030BC (open).

With a different device, use 4A0335C (flow) and 4A033JC (pulse).

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.
