Ask Dr. Z

I have a cardiac clinic patient coming in 7 day TAVR procedure follow-up. In the clinic note, MD states in assessment/plan as first listed diagnosis is "severe aortic value stenosis". Would we use Z48.812 for first listed diagnosis? In your answer for question 10857 it was stated to use Z09, but we are thinking Z48.812 is more specific to a cardiac procedure. Can you please elaborate on your answer "Do not report code I35.0, Nonrheumatic aortic (valve) stenosis, as this condition is no longer present"? Is aortic stenosis with the new aortic valve only coded as a complication because the new value completely resolves this condition?
