About 0ST50ZZ

0ST50ZZ is the ICD-10-PCS code for a resection procedure on the sacrococcygeal joint using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to other operations on joint structures, the ICD-9-CM procedure title it maps to (81.99).

For a different body part, codes include 0ST20ZZ (lumbar vertebral disc), 0ST40ZZ (lumbosacral disc), 0ST60ZZ (coccygeal joint), 0ST70ZZ (right sacroiliac joint), 0ST80ZZ (left sacroiliac joint), 0ST90ZZ (right hip joint) and 13 more.

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “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.
