0.000What This Code Means
The right side of the heart fails as a secondary consequence of left heart failure, where the left side's dysfunction causes the right side to fail.
Coding Tips
- •Verify documentation establishes a causal relationship between left heart failure and right heart failure
- •Code the left heart failure separately in addition to this code
Clinical Significance
Right heart failure due to left heart failure identifies the etiology of right ventricular dysfunction as secondary to left-sided heart disease. This is the most common cause of right heart failure and indicates biventricular disease progression. Proper coding requires both this code and the underlying left heart failure code to fully represent disease complexity.
Documentation Requirements
- ✓Provider must document right heart failure caused by or secondary to left heart failure
- ✓Left heart failure type and acuity must also be documented and coded separately
- ✓Evidence of biventricular dysfunction on echocardiogram
- ✓Signs of right heart failure: peripheral edema, jugular venous distension, hepatomegaly
- ✓Treatment plan addressing both left and right heart failure
- ✓Use additional code for left heart failure type (I50.2-, I50.3-, I50.4-)
Excludes 1 — Do NOT code together
- Right heart failure with but not due to left heart failure (I50.82)
Commonly Confused Codes
I50.82 — Biventricular heart failure: may be used when both ventricles are failing but without specifying the causal relationshipI50.810 — Right heart failure, unspecified: does not specify the etiologyI50.812 — Chronic right heart failure: does not specify left heart disease as the causeI27.81 — Cor pulmonale (chronic): right heart failure due to lung disease, not left heart diseaseI50.22 — Chronic systolic heart failure: the underlying left heart condition, coded separately
