About 0R9D4ZX

0R9D4ZX is the ICD-10-PCS code for a drainage procedure on the left temporomandibular joint using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of facial bone, the ICD-9-CM procedure title it maps to (76.11).

For a different body part, codes include 0R904ZX (occipital-cervical joint), 0R914ZX (cervical vertebral joint), 0R934ZX (cervical vertebral disc), 0R944ZX (cervicothoracic vertebral joint), 0R954ZX (cervicothoracic vertebral disc), 0R964ZX (thoracic vertebral joint) and 22 more.

The same procedure with a different approach is coded 0R9D0ZX (open) and 0R9D3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 477 (Biopsies of Musculoskeletal System and Connective Tissue with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 478 (Biopsies of Musculoskeletal System and Connective Tissue with CC) and DRG 479 (Biopsies of Musculoskeletal System and Connective Tissue without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures” and “Biopsies of Musculoskeletal System and Connective Tissue”.

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