# CPT 93321

> Medicare paid $24.97 for CPT 93321 in the office (non-facility) setting and $24.97 in a facility under the Q2 2024 Physician Fee Schedule, effective April 2024. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2024, when it decreased 1.8%.

## What it is

The narrower version of the Doppler waveform add-on to a heart ultrasound. Instead of sampling flow across all the relevant valves and chambers, the study records velocities at one or two specific points - typically to recheck a gradient already on record, or to settle a single question raised by the images. The technique is identical to the complete Doppler study; only the extent of the examination differs.
