About 0B730ZZ

0B730ZZ is the ICD-10-PCS code for a dilation procedure on the right main bronchus using an open approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to bronchial dilation, the ICD-9-CM procedure title it maps to (33.91).

For a different body part, codes include 0B710ZZ (trachea), 0B720ZZ (carina), 0B740ZZ (right upper lobe bronchus), 0B750ZZ (right middle lobe bronchus), 0B760ZZ (right lower lobe bronchus), 0B770ZZ (left main bronchus) and 3 more.

The same procedure with a different approach is coded 0B733ZZ (percutaneous), 0B734ZZ (percutaneous endoscopic), 0B737ZZ (via natural or artificial opening) and 0B738ZZ (via natural or artificial opening endoscopic).

With a different device, use 0B730DZ (intraluminal device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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