Cardiac catheterization
About 93565: Selective left chamber angiography
Selective left ventricular or left atrial angiography during cardiac catheterization is reported when catheter-directed contrast imaging assesses chamber anatomy or function.
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.

Some communities span more than one payment area. Follow a city link to compare all of its mapped areas, or check the service-location ZIP above for an address-level starting point.
Why are the office and facility amounts different?
For 93565 in El Centro, the physician’s office rate is $25.40 and the facility-setting rate is $22.11: a difference of $3.29.
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.
