About 0STF0ZZ

0STF0ZZ is the ICD-10-PCS code for a resection procedure on the right ankle 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 excision of joint, ankle, the ICD-9-CM procedure title it maps to (80.97).

For a different body part, codes include 0ST20ZZ (lumbar vertebral disc), 0ST40ZZ (lumbosacral disc), 0ST50ZZ (sacrococcygeal joint), 0ST60ZZ (coccygeal joint), 0ST70ZZ (right sacroiliac joint), 0ST80ZZ (left sacroiliac joint) and 13 more.

It is an operating-room procedure in the MS-DRG logic for DRG 492 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 493 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with CC), DRG 494 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur without CC/MCC), DRG 907 (Other O.R.
