About 07B90ZX

07B90ZX is the ICD-10-PCS code for a excision procedure on the left lymphatic, internal mammary 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 lymphatic structure, the ICD-9-CM procedure title it maps to (40.11).

For a different body part, codes include 07B00ZX (lymphatic, head), 07B10ZX (lymphatic, right neck), 07B20ZX (lymphatic, left neck), 07B30ZX (lymphatic, right upper extremity), 07B40ZX (lymphatic, left upper extremity), 07B50ZX (lymphatic, right axillary) and 14 more.

The same procedure with a different approach is coded 07B93ZX (percutaneous) and 07B94ZX (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Circulatory System O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and 3 more.

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