About 0YMH0ZZ

0YMH0ZZ is the ICD-10-PCS code for a reattachment procedure on the right lower leg 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 lower leg or ankle reattachment, the ICD-9-CM procedure title it maps to (84.27).

For a different body part, codes include 0YM00ZZ (right buttock), 0YM10ZZ (left buttock), 0YM20ZZ (right hindquarter), 0YM30ZZ (left hindquarter), 0YM40ZZ (bilateral hindquarter), 0YM50ZZ (right inguinal region) and 24 more.

It is an operating-room procedure in the MS-DRG logic for DRG 469 (Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity with MCC or Total Ankle Replacement), DRG 470 (Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity without 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 956 (Limb Reattachment, Hip and Femur Procedures for Multiple Significant Trauma), under the surgical categories “Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity or Total Ankle Replacement”, “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.
