About 4A0J74Z

4A0J74Z is the ICD-10-PCS code for a measurement procedure on the products of conception, nervous using a via natural or artificial opening approach with electrical activity. 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 fetal monitoring, the ICD-9-CM procedure title it maps to (75.34).

For a different body part, codes include 4A0074Z (central nervous), 4A0174Z (peripheral nervous), 4A0274Z (cardiac) and 4A0H74Z (products of conception, cardiac).

The same procedure with a different approach is coded 4A0J84Z (via natural or artificial opening endoscopic) and 4A0JX4Z (external).

With a different device, use 4A0J72Z (conductivity) and 4A0J7BZ (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.
