Cardiac catheterization
About 93564: Selective bypass graft angiography injection
Reports selective contrast imaging of aortocoronary venous bypass grafts during cardiac catheterization, such as graft assessment in a patient with prior CABG.
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.

Why are the office and facility amounts different?
For 93564 in Delaware, the physician’s office rate is $52.68 and the facility-setting rate is $46.74: a difference of $5.94.
The calculation uses a different practice-expense RVU for each setting. Both amounts here are physician fee-schedule amounts. The facility figure does not include a hospital’s separate charges, so this comparison does not tell you the total cost of receiving care in each setting.

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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
