A code also note instructs that 2 codes may be required to fully describe a condition but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the encounter.

- Code First annotations, or
- Excludes1 annotations, or
- Excludes2 annotations, or
- Includes annotations, or

that may be applicable to
I34.0:
- Mitral valve regurgitation
- Non-rheumatic mitral regurgitation
Clinical Information
- Backflow of blood from the left ventricle into the left atrium due to imperfect closure of the mitral valve. This can lead to mitral valve regurgitation.
- Backflow of blood from the left ventricle into the left atrium, owing to imperfect functioning of the mitral valve.
- Blood flows backward because the mitral valve closes improperly
- Dysfunction of the mitral valve, with incomplete valve closure resulting in valvular regurgitation.
- The backward flow of blood from the left ventricle into the left atrium, owing to insufficiency of the mitral valve; it may be acute or chronic, usually due to mitral valve prolapse, rheumatic heart disease or a complication of cardiac dilatation.
ICD-10-CM I34.0 is grouped within Diagnostic Related Group(s) (MS-DRG v40.0):
