About 0HMUXZZ

0HMUXZZ is the ICD-10-PCS code for a reattachment procedure on the left breast 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 mammoplasty, the ICD-9-CM procedure title it maps to (85.89).

For a different body part, codes include 0HM0XZZ (skin, scalp), 0HM1XZZ (skin, face), 0HM2XZZ (skin, right ear), 0HM3XZZ (skin, left ear), 0HM4XZZ (skin, neck), 0HM5XZZ (skin, chest) and 21 more.

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.
