0.000What This Code Means
The heart fails despite increased blood flow and output, often seen in conditions like severe anemia, hyperthyroidism, or sepsis where the body's metabolic demands exceed the heart's capacity.
Coding Tips
- •Identify and document the underlying cause of high output state (anemia, infection, thyroid disease, etc.)
- •This is a less common heart failure type; verify documentation supports this diagnosis
Clinical Significance
High output heart failure is a unique form where the heart fails despite having normal or elevated cardiac output, because the body's demand exceeds the heart's ability to supply. This occurs in conditions such as severe anemia, thyrotoxicosis, arteriovenous fistula, and Paget disease. Proper identification is important because treatment differs fundamentally from other forms of heart failure.
Documentation Requirements
- ✓Provider must document high output heart failure specifically
- ✓Underlying cause: severe anemia, thyrotoxicosis, arteriovenous fistula, beriberi, Paget disease
- ✓Hemodynamic evidence of elevated cardiac output with symptoms of heart failure
- ✓Cardiac function assessment showing increased cardiac output
- ✓Treatment plan addressing the underlying cause
- ✓Code the underlying condition in addition to the heart failure
Commonly Confused Codes
I50.9 — Heart failure, unspecified: generic heart failure without specifying the high output mechanismI50.22 — Chronic systolic heart failure: low output failure, fundamentally different mechanismI50.32 — Chronic diastolic heart failure: failure due to filling impairment, not excessive demandI50.89 — Other heart failure: other types not otherwise classifiedD64.9 — Anemia, unspecified: may be the underlying cause of high output failure but is not the heart failure code
