About I50.81

I50.81 is the ICD-10-CM diagnosis code for right heart failure. It belongs to category I50 (heart failure), block I30-I5A (other forms of heart disease) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within I50.8 (other heart failure), I50.81 is specifically for right heart failure. Related codes cover biventricular heart failure (I50.82), high output heart failure (I50.83), end stage heart failure (I50.84) and other heart failure (I50.89).

To report this condition, pick the subcode that matches the documentation: I50.810 (unspecified), I50.811 (failure), I50.812 (failure), I50.813 (failure) and I50.814 (due to left heart failure).

Code first: heart failure complicating abortion or ectopic or molar pregnancy (O00-O07, O08.8), heart failure due to hypertension (I11.0), heart failure due to hypertension with chronic kidney disease (I13.-), heart failure following surgery (I97.13-) and 2 more.
