I05.1 is a billable ICD code used to specify a diagnosis of rheumatic mitral insufficiency. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code I051 is used to code Mitral insufficiency

Mitral insufficiency (MI), mitral regurgitation or mitral incompetence is a disorder of the heart in which the mitral valve does not close properly when the heart pumps out blood. It is the abnormal leaking of blood backwards from the left ventricle, through the mitral valve, into the left atrium, when the left ventricle contracts, i.e. there is regurgitation of blood back into the left atrium. MI is the most common form of valvular heart disease.
