About 0TNB7ZZ

0TNB7ZZ is the ICD-10-PCS code for a release procedure on the bladder using a via natural or artificial opening 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 transurethral lysis of intraluminal adhesions, the ICD-9-CM procedure title it maps to (57.41).

For a different body part, codes include 0TN07ZZ (right kidney), 0TN17ZZ (left kidney), 0TN37ZZ (right kidney pelvis), 0TN47ZZ (left kidney pelvis), 0TN67ZZ (right ureter), 0TN77ZZ (left ureter) and 2 more.

The same procedure with a different approach is coded 0TNB0ZZ (open), 0TNB3ZZ (percutaneous), 0TNB4ZZ (percutaneous endoscopic) and 0TNB8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 668 (Transurethral Procedures with MCC), DRG 669 (Transurethral Procedures with CC) and DRG 670 (Transurethral Procedures without CC/MCC), under the surgical category “Transurethral Procedures”.

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