What 33904 covers
This add-on represents treatment of an additional pulmonary artery vessel during a catheter-based revascularization. It may be used in cases such as branch pulmonary artery narrowing in patients with congenital heart disease or after prior repair. The interventional cardiologist or another physician performing the catheter procedure documents the vessels treated and the revascularization performed.
Report 33904 with the applicable primary code from 33900–33903, which describes the first vessel and distinguishes native connections and unilateral or bilateral treatment. Use one unit for each additional vessel treated beyond that primary vessel. The procedure report should identify the treated vessels and support the vessel count and primary-code selection. CMS classifies 33904 as an add-on: it is billed only with a primary procedure, and payment is within that procedure’s global period.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Report one unit for each additional pulmonary artery vessel treated beyond the vessel represented by the primary code.
Can 33904 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure, with payment within that procedure’s global period.
What documentation supports an additional-vessel unit?

How does 33904 differ from codes 33900–33903?
Codes 33900–33903 describe the primary vessel and classify the native connections and laterality. Code 33904 captures each additional vessel treated.
