About 0PB40ZX

0PB40ZX is the ICD-10-PCS code for a excision procedure on the thoracic vertebra 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 biopsy of bone, other bones, the ICD-9-CM procedure title it maps to (77.49).

For a different body part, codes include 0PB00ZX (sternum), 0PB10ZX (ribs, 1 to 2), 0PB20ZX (ribs, 3 or more), 0PB30ZX (cervical vertebra), 0PB50ZX (right scapula), 0PB60ZX (left scapula) and 20 more.

The same procedure with a different approach is coded 0PB43ZX (percutaneous) and 0PB44ZX (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System 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 Respiratory System O.R. Procedures”, “Biopsies of Musculoskeletal System and Connective Tissue” 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.
