What 93575 covers
93575 captures selective contrast angiography of major aortopulmonary collateral arteries (MAPCAs) during congenital cardiac catheterization. The operator selectively enters collateral vessels and injects contrast to show their origins, courses, and pulmonary distribution. This may be useful in complex congenital heart disease, including pulmonary atresia, when MAPCAs supply lung segments. A congenital or interventional cardiologist typically performs the service in a cardiac catheterization laboratory.
Report 93575 when selective imaging of MAPCAs is performed, rather than for a general pulmonary artery injection. The catheterization report should identify the collateral vessels entered, describe the contrast imaging and findings, and explain the clinical reason for the study. This is an add-on code: submit it with a primary procedure, not as a standalone service. CMS pays it within the primary 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.

- 93573Pulmonary angiography
- 93573 describes selective bilateral pulmonary angiography. 93575 is specific to selective imaging of major aortopulmonary collateral arteries.
- 93574Pulmonary venography
- 93574 is for selective pulmonary venous angiography. Use 93575 when the selectively imaged vessels are MAPCAs.
93575 billing questions
Can 93575 be reported by itself?
No. It is an add-on code and must be reported with a primary procedure; CMS pays it within that procedure’s global period.
How is 93575 different from 93568?
93575 is for selective imaging of MAPCAs. 93568 describes nonselective pulmonary angiography, rather than selective collateral-vessel imaging.
How is 93575 different from 93573?
93575 targets major aortopulmonary collateral arteries. 93573 describes selective bilateral pulmonary angiography, not selective MAPCA angiography.
What documentation supports reporting 93575?
The catheterization report should identify the MAPCA vessel or vessels selectively entered and document the contrast imaging, findings, and clinical purpose.
Does 93575 describe pulmonary venous imaging?
No. It describes selective MAPCA imaging; 93574 is the neighboring code for selective pulmonary venous 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.
