About 0Q944ZX

0Q944ZX is the ICD-10-PCS code for a drainage procedure on the right acetabulum 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 0Q904ZX (lumbar vertebra), 0Q914ZX (sacrum), 0Q924ZX (right pelvic bone), 0Q934ZX (left pelvic bone), 0Q954ZX (left acetabulum), 0Q964ZX (right upper femur) and 18 more.

The same procedure with a different approach is coded 0Q940ZX (open) and 0Q943ZX (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 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Biopsies of Musculoskeletal System and Connective Tissue”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other Kidney and Urinary Tract Procedures” and 3 more.

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