Issue with Misclassification of diagnosisstrings?

[vanessailana]

Hello,

I was working with this dataset and noticed that some codes appear to be misclassified.

For example, the diagnosis string "cardiovascular chest pain / ASHD coronary artery disease / other biological bypass graft" is assigned to I25.810. This code represents "Atherosclerosis of coronary artery bypass graft(s) without angina pectoris"

However, I am wondering if I25.73, which seems similar, is actually more appropriate, as the definition of this code is "Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with angina pectoris"

Could there be an issue with misclassification?
