About 0BHT42Z

0BHT42Z is the ICD-10-PCS code for a insertion procedure on the diaphragm using a percutaneous endoscopic approach with monitoring device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to other operations on diaphragm, the ICD-9-CM procedure title it maps to (34.89).

For a different body part, codes include 0BH042Z (tracheobronchial tree), 0BHK42Z (right lung) and 0BHL42Z (left lung).

The same procedure with a different approach is coded 0BHT02Z (open) and 0BHT32Z (percutaneous).

With a different device, use 0BHT4MZ (diaphragmatic pacemaker lead) and 0BHT4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical category “Major Chest Procedures”.

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