mitral or aortic valve repair or replacement

Please tell me the correct code for mitral/aortic valve replacement or repair.

mitral/aortic valve replace V43.3

mitral/aortic valve repair V58.49

are these correct? Please advise and thank you.

re: mitral or aortic valve repair or replacement

No. You code the condition responsible for surgery (ex, 424.1).
Aortic (valve):
incompetence NOS of specified cause, except rheumatic
insufficiency NOS of specified cause, except rheumatic
regurgitation NOS of specified cause, except rheumatic
stenosis NOS of specified cause, except rheumatic.
The V series is for aftercare or status codes.
