About 0YQL4ZZ
0YQL4ZZ is the ICD-10-PCS code for a repair procedure on the left ankle region using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.
In plain terms, this corresponds to other operations on musculoskeletal system, the ICD-9-CM procedure title it maps to (84.99).
For a different body part, codes include 0YQ04ZZ (right buttock), 0YQ14ZZ (left buttock), 0YQ54ZZ (right inguinal region), 0YQ64ZZ (left inguinal region), 0YQ74ZZ (right femoral region), 0YQ84ZZ (left femoral region) and 23 more.
The same procedure with a different approach is coded 0YQL0ZZ (open), 0YQL3ZZ (percutaneous) and 0YQLXZZ (external).
It is an operating-room procedure in the MS-DRG logic for 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), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
