Sequence# 13319 - 13321 Dobutamine Challenge Performed, Flow Reserve Present, and Aortic Stenosis Type (Video 2:11)

Video Transcription

Video Summary

The video transcript discusses the use of a dibutamine challenge in evaluating patients with aortic stenosis. Sequence 13319 is the parent field for sequences 13320 and 13321. A dibutamine challenge is used to distinguish between true severe and pseudo-severe aortic stenosis. If a dibutamine challenge was performed, sequence 13319 would be coded as "yes". Sequence 13320 would be coded as "yes" if there is an increase in stroke volume index of 20% or more as a result of the challenge. Sequence 13321 is used to indicate the type of aortic stenosis documented during the challenge.
