About 4A040B3

4A040B3 is the ICD-10-PCS code for a measurement procedure on the venous using an open approach with pressure (qualifier: pulmonary). 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, other specified and unspecified vessels, the ICD-9-CM procedure title it maps to (00.69).

For a different body part, codes include 4A030B3 (arterial).

The same procedure with a different approach is coded 4A043B3 (percutaneous).

With a different device, use 4A04053 (flow) and 4A040J3 (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.
