About 4A133JC

4A133JC is the ICD-10-PCS code for a monitoring procedure on the arterial using a percutaneous approach with pulse (qualifier: coronary). In ICD-10-PCS, monitoring means determining the level of a physiological or physical function repetitively over a period of time.

In plain terms, this corresponds to other nonoperative cardiac and vascular measurements, the ICD-9-CM procedure title it maps to (89.59).

The same procedure with a different approach is coded 4A130JC (open).

With a different device, use 4A1335C (flow) and 4A133BC (pressure).

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.
