About 31637: Additional bronchial stent placement
Report this add-on when bronchoscopy places a bronchial stent in an additional bronchus beyond the initial bronchus treated during the same procedure.
This add-on describes bronchoscopic placement of a stent in an additional bronchus after the initial bronchus has been treated. Interventional pulmonologists and thoracic surgeons may use it when airway narrowing or obstruction, such as from a tumor or stenosis, involves more than one bronchus. Placement is performed with a rigid or flexible bronchoscope, commonly in a hospital setting.
Report 31637 for each additional bronchus treated, not for each extra stent placed in the same bronchus. The procedure record should identify the bronchus receiving the additional stent and support that placement occurred during the session. Pair it with the primary bronchial stent placement code, 31636, for the initial bronchus. CMS classifies 31637 as an add-on that is billed only with a primary procedure, with payment within that procedure’s global period.

31637 billing questions
When should 31637 be reported instead of 31636?
Use 31636 for the initial bronchus receiving a bronchial stent. Report 31637 for each additional bronchus treated during the procedure.
Does each additional stent require a unit of 31637?
No. The add-on is based on each additional bronchus, not the number of stents placed in the same bronchus.
Can 31637 be billed without 31636?
No. CMS identifies 31637 as an add-on that must be billed with a primary procedure; 31636 is the primary code for initial bronchial stent placement.
What documentation supports reporting an additional unit?
Document the bronchoscopic stent placement and identify each additional bronchus treated beyond the initial bronchus.
Can a modifier make 31637 independently reportable?
No. A modifier does not replace the required primary procedure pairing.
