About 4A068BZ

4A068BZ is the ICD-10-PCS code for a measurement procedure on the lymphatic using a via natural or artificial opening endoscopic approach with pressure. 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 diagnostic procedures on lymphatic structures, the ICD-9-CM procedure title it maps to (40.19).

For a different body part, codes include 4A0B8BZ (gastrointestinal), 4A0C8BZ (biliary), 4A0D8BZ (urinary) and 4A0J8BZ (products of conception, nervous).

The same procedure with a different approach is coded 4A060BZ (open), 4A063BZ (percutaneous) and 4A067BZ (via natural or artificial opening).

With a different device, use 4A0685Z (flow).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
