About 0HNV8ZZ

0HNV8ZZ is the ICD-10-PCS code for a release procedure on the bilateral breast using a via natural or artificial opening 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 other mammoplasty, the ICD-9-CM procedure title it maps to (85.89).

For a different body part, codes include 0HNT8ZZ (right breast), 0HNU8ZZ (left breast), 0HNW8ZZ (right nipple) and 0HNX8ZZ (left nipple).

The same procedure with a different approach is coded 0HNV0ZZ (open), 0HNV3ZZ (percutaneous) and 0HNV7ZZ (via natural or artificial opening).

It is an operating-room procedure in the MS-DRG logic for DRG 584 (Breast Biopsy, Local Excision and Other Breast Procedures with CC/MCC) and DRG 585 (Breast Biopsy, Local Excision and Other Breast Procedures without CC/MCC), under the surgical category “Breast Biopsy, Local Excision and Other Breast Procedures”.

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