416.9
ICD-9-CMThis code signifies a long-standing condition where the right side of the heart is affected due to a primary disease of the lungs or their vasculature. It indicates a chronic form of cor pulmonale without further specification of the underlying cause or specific cardiac involvement.
Use this code when documentation clearly states "chronic pulmonary heart disease" or "chronic cor pulmonale" without specifying the etiology (e.g., COPD, pulmonary embolism). It is appropriate when the physician has not identified a more specific cause for the right heart strain.
