About 0TNC4ZZ

0TNC4ZZ is the ICD-10-PCS code for a release procedure on the bladder neck using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to laparoscopic lysis of perivesical adhesions, the ICD-9-CM procedure title it maps to (59.12).

For a different body part, codes include 0TN04ZZ (right kidney), 0TN14ZZ (left kidney), 0TN34ZZ (right kidney pelvis), 0TN44ZZ (left kidney pelvis), 0TN64ZZ (right ureter), 0TN74ZZ (left ureter) and 2 more.

The same procedure with a different approach is coded 0TNC0ZZ (open), 0TNC3ZZ (percutaneous), 0TNC7ZZ (via natural or artificial opening) and 0TNC8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 662 (Minor Bladder Procedures with MCC), DRG 663 (Minor Bladder Procedures with CC), DRG 664 (Minor Bladder Procedures without CC/MCC), DRG 715 (Male Reproductive System and Other O.R. Procedures for Malignancy with CC/MCC), DRG 716 (Male Reproductive System and Other O.R. Procedures for Malignancy without CC/MCC) and DRG 717 (Other Male Reproductive System O.R. Procedures with CC/MCC), under the surgical categories “Minor Bladder Procedures”, “”, “Other Male Reproductive System O.R. Procedures” and 5 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
