What 93565 covers
During cardiac catheterization, the cardiologist directs contrast into the left ventricle or left atrium and interprets the resulting angiographic images. The study may help evaluate chamber size, motion, or structural findings when that information is needed during the catheterization. It is typically performed in a hospital cardiac catheterization laboratory by the physician conducting the procedure.
Report 93565 only with an applicable primary cardiac catheterization procedure; it is not a stand-alone service. The record should identify the chamber selectively imaged, the contrast injection, and the clinical findings assessed. Distinguish this left-sided chamber study from injections for coronary arteries, bypass grafts, or right-sided chambers. CMS treats 93565 as an add-on, with payment within the primary procedure's global period.

93565 billing questions
Can 93565 be reported by itself?
No. It is an add-on for selective left ventricular or left atrial angiography performed during a primary cardiac catheterization procedure.
How does 93565 differ from 93563?
93565 describes selective imaging of the left ventricle or left atrium. 93563 is for selective coronary angiography.
How does 93565 differ from 93566?
93565 is for the left ventricle or left atrium; 93566 is for the right ventricle or right atrium.
What documentation supports reporting 93565?
Document which left-sided chamber was selectively injected, the contrast imaging performed, and the findings interpreted. The record should support a distinct chamber angiography service during the catheterization.
Is 93565 reported with a primary cardiac catheterization code?
Yes. Report it with the applicable primary catheterization procedure when the selective left ventricular or left atrial angiography is performed.
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.
