About 0KBJ0ZX

0KBJ0ZX is the ICD-10-PCS code for a excision procedure on the left thorax muscle using an open approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to open biopsy of soft tissue, the ICD-9-CM procedure title it maps to (83.21).

For a different body part, codes include 0KB00ZX (head muscle), 0KB10ZX (facial muscle), 0KB20ZX (right neck muscle), 0KB30ZX (left neck muscle), 0KB40ZX (tongue, palate, pharynx muscle), 0KB50ZX (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KBJ3ZX (percutaneous) and 0KBJ4ZX (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Respiratory System O.R. Procedures”, “Soft Tissue Procedures” and 2 more.

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