About 0KB50ZX

0KB50ZX is the ICD-10-PCS code for a excision procedure on the right shoulder 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), 0KB60ZX (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KB53ZX (percutaneous) and 0KB54ZX (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 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC) and DRG 502 (Soft Tissue Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Soft Tissue Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 1 more.
