About 07B70ZX

07B70ZX is the ICD-10-PCS code for a excision procedure on the lymphatic, thorax 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 07B73ZX (percutaneous) and 07B74ZX (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 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Respiratory System O.R. Procedures”, “Other Circulatory System O.R. Procedures” and 4 more.

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