About 0P9T4ZX

0P9T4ZX is the ICD-10-PCS code for a drainage procedure on the right finger phalanx 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 bone, other bones, the ICD-9-CM procedure title it maps to (77.49).

For a different body part, codes include 0P904ZX (sternum), 0P914ZX (ribs, 1 to 2), 0P924ZX (ribs, 3 or more), 0P934ZX (cervical vertebra), 0P944ZX (thoracic vertebra), 0P954ZX (right scapula) and 20 more.

The same procedure with a different approach is coded 0P9T0ZX (open) and 0P9T3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 479 (Biopsies of Musculoskeletal System and Connective Tissue without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Biopsies of Musculoskeletal System and Connective Tissue”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures of the Blood and Blood Forming Organs”.

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