What 93566 covers

This add-on describes selective contrast imaging of the right atrium or right ventricle during cardiac catheterization. A cardiologist or other physician performing the catheterization may use it to evaluate right-sided chamber anatomy, such as when assessing a congenital or structural abnormality. The code covers the injection and its imaging supervision, interpretation, and report; routine catheter placement and pressure measurements alone do not describe this angiographic service.

Report 93566 only with an eligible primary cardiac catheterization procedure, not as a standalone service. The record should identify the selectively imaged chamber and support that a contrast injection and angiographic study were performed, with the findings documented. CMS treats this add-on as paid within the primary procedure's global period. The imaging supervision, interpretation, and report are part of this injection service.

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.

93566 billing questions

Can 93566 be reported by itself?

No. It is an add-on code and must be reported with an eligible primary cardiac catheterization procedure.

How is 93566 different from 93565?

93566 reports selective imaging of the right atrium or right ventricle. 93565 is for left ventricular or left atrial angiography.

Does a right heart catheterization with pressure measurements support 93566?

Pressure measurements alone do not describe selective right-sided chamber angiography. The record should support a contrast injection and angiographic imaging of the right atrium or ventricle.

Is the angiographic interpretation separately reported?

The code includes imaging supervision, interpretation, and reporting for the injection study.

What should the procedure note identify?

Document which right-sided chamber was selectively imaged, the injection and angiographic study, and the resulting findings.

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.
