Wiki Carotid artery plaque diagnosis

[barrski]

Patient came in for a carotid doppler for dizziness. Results state 'Less than 39% degree stenosis is identified in the internal carotid arteries bilaterally'.

I know there are levels of stenosis but does less than 39% warrant a diagnosis of carotid stenosis - 433.10 / 433.30??

The findings mention 'very small amount of plaquing is noted'.

Thank you

I don't have any reference and could possibly be misguided but I have always been told not to code stenosis unless it is documented 50% or greater.

That's what I was thinking but I wanted to know what others thought.

Thank you.
