About 4A1J82Z

4A1J82Z is the ICD-10-PCS code for a monitoring procedure on the products of conception, nervous using a via natural or artificial opening endoscopic approach with conductivity. 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 fetal monitoring, the ICD-9-CM procedure title it maps to (75.34).

The same procedure with a different approach is coded 4A1J72Z (via natural or artificial opening) and 4A1JX2Z (external).

With a different device, use 4A1J84Z (electrical activity) and 4A1J8BZ (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.
