About 079P0ZX

079P0ZX is the ICD-10-PCS code for a drainage procedure on the spleen using an open 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 open biopsy of spleen, the ICD-9-CM procedure title it maps to (41.33).

For a different body part, codes include 07900ZX (lymphatic, head), 07910ZX (lymphatic, right neck), 07920ZX (lymphatic, left neck), 07930ZX (lymphatic, right upper extremity), 07940ZX (lymphatic, left upper extremity), 07950ZX (lymphatic, right axillary) and 15 more.

The same procedure with a different approach is coded 079P3ZX (percutaneous) and 079P4ZX (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 799 (Splenic Procedures with MCC), DRG 800 (Splenic Procedures with CC), DRG 801 (Splenic Procedures without CC/MCC), DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), DRG 821 (Lymphoma and Leukemia with Major O.R. Procedures with CC) and DRG 822 (Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC), under the surgical categories “Splenic Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures”.

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