About 4A04351

4A04351 is the ICD-10-PCS code for a measurement procedure on the venous using a percutaneous approach with flow (qualifier: peripheral). 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).

For a different body part, codes include 4A03351 (arterial).

The same procedure with a different approach is coded 4A04051 (open) and 4A04X51 (external).

With a different device, use 4A043B1 (pressure), 4A043J1 (pulse) and 4A043R1 (saturation).

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.
