About 0BTH4ZZ

0BTH4ZZ is the ICD-10-PCS code for a resection procedure on the lung lingula using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to thoracoscopic segmental resection of lung, the ICD-9-CM procedure title it maps to (32.30).

For a different body part, codes include 0BT14ZZ (trachea), 0BT24ZZ (carina), 0BT34ZZ (right main bronchus), 0BT44ZZ (right upper lobe bronchus), 0BT54ZZ (right middle lobe bronchus), 0BT64ZZ (right lower lobe bronchus) and 13 more.

The same procedure with a different approach is coded 0BTH0ZZ (open).

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 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 “Major Chest Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures”, “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures” and 2 more.

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