About 0HM4XZZ

0HM4XZZ is the ICD-10-PCS code for a reattachment procedure on the skin, neck 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.

Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R.
