What 93564 covers

During cardiac catheterization, the cardiologist selectively injects contrast into one or more aortocoronary venous bypass grafts to visualize the grafts and their connections. A common setting is evaluation of graft patency in a patient with prior coronary artery bypass surgery. This is an imaging injection service, not a graft intervention; the catheterization and any treatment are represented by their applicable codes.

Report 93564 only with a primary cardiac catheterization procedure, and only when selective graft opacification is performed. The record should identify the grafts injected and support that selective imaging was carried out and interpreted. This add-on is paid within the primary procedure’s global period. It is not reported as a stand-alone service. When multiple grafts are selectively imaged during the same catheterization, report the add-on for the service rather than treating each graft as a separate unit.

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.

93564 billing questions

How does 93564 differ from 93563?

93564 captures selective imaging of aortocoronary venous bypass grafts. 93563 is for selective coronary angiography of the native coronary arteries.

Which primary procedure should accompany 93564?

Report it with the applicable cardiac catheterization code, such as 93459 for left heart catheterization with coronary angiography that includes bypass grafts. It is an add-on and cannot stand alone.

Do I report one unit for each graft?

No. The add-on represents selective opacification of one or more aortocoronary venous bypass grafts during the catheterization, rather than a separate unit for every graft.

What documentation supports 93564?

Document the selective graft imaging performed, including which bypass grafts were injected and the resulting imaging interpretation. The record should distinguish graft opacification from imaging of native coronary arteries.

Can 93564 be billed by itself?

No. It must be reported with a primary cardiac catheterization procedure and is paid within that procedure’s global period.

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.
