What 93573 covers
During cardiac catheterization, the operator selectively positions a catheter in the pulmonary arteries and injects contrast to image both sides. The resulting angiographic views can help define pulmonary artery anatomy, including abnormalities relevant to congenital heart disease. A congenital cardiologist or other physician performing the catheterization typically carries out the injections and interprets the images in a cardiac catheterization laboratory.
Report 93573 as an add-on only with an eligible primary cardiac catheterization procedure, not as a standalone service. Choose it when selective pulmonary arterial angiography is performed bilaterally; unilateral selective imaging is represented by a different code, while nonselective imaging uses another approach. The record should support selective catheter placement, contrast injections into both pulmonary arterial systems, the images obtained, and the physician’s interpretation. CMS identifies this as an add-on paid within the primary procedure’s global period.

93573 billing questions
When should 93573 be chosen instead of 93569?
Use 93573 when selective pulmonary arterial angiography is performed bilaterally. Code 93569 describes the unilateral selective service.
Can 93573 be billed by itself?
No. It is an add-on code and must be reported with an eligible primary cardiac catheterization procedure.
Does this code include image interpretation?
Yes. The angiography service includes imaging supervision, interpretation, and reporting; document the images and the physician’s findings.
What documentation supports bilateral reporting?
Document selective catheter placement and contrast imaging of both pulmonary arterial systems, along with the resulting interpretation.
How does 93573 differ from nonselective pulmonary angiography?
93573 represents selective catheterization and imaging of both pulmonary arterial systems. Code 93568 describes nonselective pulmonary arterial angiography.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
