Nutritional and metabolic cardiomyopathy

This code represents a form of heart muscle disease (cardiomyopathy) directly caused by deficiencies or imbalances in essential nutrients, or by metabolic disorders. It signifies cardiac dysfunction resulting from the body's inability to properly process or utilize nutrients, leading to structural and functional changes in the myocardium.

Use this code when documentation clearly links cardiomyopathy to a specific nutritional deficiency (e.g., thiamine deficiency, selenium deficiency) or a metabolic derangement (e.g., carnitine deficiency, hemochromatosis affecting the heart). Supporting documentation should include diagnostic findings of cardiomyopathy and evidence of the underlying nutritional or metabolic cause.

• Always code the underlying nutritional deficiency or metabolic disorder first, followed by this code as a manifestation.
• Distinguish from other specific types of cardiomyopathy (e.g., alcoholic, ischemic) where the etiology is different.
• Ensure physician documentation explicitly states the causal link between the nutritional/metabolic issue and the cardiomyopathy.
