I34: Nonrheumatic mitral valve disorders

Non-billable headerICD-10-CM

I34 is a non-billable header ICD-10-CM code for nonrheumatic mitral valve disorders. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

mitral valve disease (I05.9)
mitral valve failure (I05.8)
mitral valve stenosis (I05.0)
mitral valve disorder of unspecified cause with diseases of aortic and/or tricuspid valve(s) (I08.-)
mitral valve disorder of unspecified cause with mitral stenosis or obstruction (I05.0)
mitral valve disorder specified as congenital (Q23.2, Q23.9)
mitral valve disorder specified as rheumatic (I05.-)

Other codes that can never be billed with I34

Their own Excludes1 notes name this code, so the conflict is not listed above.
