# CPT 78492

> CPT 78492 carries status C (carrier-priced) in the Q2 2023 release, so there is no single national rate — Medicare contractors publish their own amounts. Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. Contractor-published amounts on file range $1,477.42–$1,608.02 across 3 localities; enter a ZIP for the exact local amount.

## What it is

Blood-flow imaging of the heart muscle done with a PET scanner instead of a conventional gamma camera. A short-lived tracer such as rubidium or ammonia is injected, and PET records where it reaches the heart wall, generally with sharper images and better correction for body habitus than SPECT, plus the ability to put an actual number on blood flow. This is the multiple-study entry, meaning imaging is performed both at rest and under pharmacologic stress so the two can be compared; the companion code covers a single study alone.
