About 4A043B2

4A043B2 is the ICD-10-PCS code for a measurement procedure on the venous using a percutaneous approach with pressure (qualifier: portal). 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 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 4A040B2 (open) and 4A044B2 (percutaneous endoscopic).

With a different device, use 4A04352 (flow) and 4A043J2 (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.
