Wiki Mitral Valve regurgitation

[cathydixson]

I'm a student and working on questions in the 2012 Step by Step workbook.

One of the questions for a diagnoses code reads:
Mitral valve regurgitation as a late effect of Fen-Phen.

Curious as to how you would code this. There are two codes for the answer.

Thanks.

424.0 and then find the late effect of Fen-Phen.

That's what I'm asking for - the diagnosis code for Late Effect of Fen-Phen. What would be the code?
