I34 — Nonrheumatic mitral valve disorders
Is I34 billable?
No — I34 is a non-billable header code. I34 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 6 billable codes beneath I34.

Excludes1 — never code together
The conditions below can never be reported together with I34 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- 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.-)
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I34, but a patient may have both at the same time. When documentation supports it, I34 and the excluded code may both be reported.

- complications of pregnancy, childbirth and the puerperium (O00-O9A)
