Unsp combined systolic and diastolic (congestive) hrt fail

This code represents a form of heart failure where the heart has difficulty both pumping blood effectively (systolic dysfunction) and relaxing to fill with blood adequately (diastolic dysfunction). The "unspecified" nature indicates that the specific type or acuity of the combined failure is not further detailed in the medical record.

Use this code when the provider documents "combined systolic and diastolic heart failure" or "congestive heart failure with both systolic and diastolic dysfunction," but does not specify the acuity (e.g., acute, chronic, acute on chronic). This code is appropriate when the documentation clearly indicates both types of dysfunction are present without further specificity.

• Avoid using this code if the documentation specifies acute, chronic, or acute on chronic combined heart failure; more specific codes exist.
• Ensure the medical record explicitly states both systolic and diastolic dysfunction are present; do not assume.
• Query the provider for further specificity (e.g., acute, chronic) if only "combined heart failure" is documented.
