Exercise Testing During a Heart Catheterization

Maine rates for HCPCS 93464

This covers an additional step performed during a heart catheterization in which the patient exercises, such as pedaling a small stationary device, while pressures and blood flow inside the heart are measured. This helps show how the heart responds to physical exertion, beyond what resting measurements alone can show. It is added on to the main heart catheterization procedure.
