About 07BM4ZX

07BM4ZX is the ICD-10-PCS code for a excision procedure on the thymus using a percutaneous endoscopic 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 thymus, the ICD-9-CM procedure title it maps to (07.16).

For a different body part, codes include 07B04ZX (lymphatic, head), 07B14ZX (lymphatic, right neck), 07B24ZX (lymphatic, left neck), 07B34ZX (lymphatic, right upper extremity), 07B44ZX (lymphatic, left upper extremity), 07B54ZX (lymphatic, right axillary) and 14 more.

The same procedure with a different approach is coded 07BM0ZX (open) and 07BM3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures 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 “Major Chest Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures of the Blood and Blood Forming Organs” and 2 more.

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