About 0KB44ZX

0KB44ZX is the ICD-10-PCS code for a excision procedure on the tongue, palate, pharynx muscle using a percutaneous endoscopic 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 other diagnostic procedures on muscle, tendon, fascia, and bursa, including that of hand, the ICD-9-CM procedure title it maps to (83.29).

For a different body part, codes include 0KB04ZX (head muscle), 0KB14ZX (facial muscle), 0KB24ZX (right neck muscle), 0KB34ZX (left neck muscle), 0KB54ZX (right shoulder muscle), 0KB64ZX (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KB40ZX (open) and 0KB43ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for 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 category “Soft Tissue Procedures”.

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