About 0XM40ZZ

0XM40ZZ is the ICD-10-PCS code for a reattachment procedure on the right axilla using an open 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 upper arm reattachment, the ICD-9-CM procedure title it maps to (84.24).

For a different body part, codes include 0XM00ZZ (right forequarter), 0XM10ZZ (left forequarter), 0XM20ZZ (right shoulder region), 0XM30ZZ (left shoulder region), 0XM50ZZ (left axilla), 0XM60ZZ (right upper extremity) and 21 more.

It is an operating-room procedure in the MS-DRG logic for DRG 483 (Major Joint or Limb Reattachment Procedures of Upper Extremities), 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 956 (Limb Reattachment, Hip and Femur Procedures for Multiple Significant Trauma), under the surgical categories “Major Joint or Limb Reattachment Procedures of Upper Extremities”, “Other O.R. Procedures for Injuries” and “Limb Reattachment, Hip and Femur Procedures for Multiple Significant Trauma”.

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