About 0HMXXZZ

0HMXXZZ is the ICD-10-PCS code for a reattachment procedure on the left nipple using an external approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

In plain terms, this corresponds to other repair or reconstruction of nipple, the ICD-9-CM procedure title it maps to (85.87).

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), DRG 585 (Breast Biopsy, Local Excision and Other Breast Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R.
