Iatrogenic carnitine deficiency

This code signifies a carnitine deficiency that is a direct consequence of medical intervention, such as drug therapy or surgical procedures. It indicates a secondary carnitine deficiency caused by external factors rather than an inherited metabolic disorder.

Use this code when documentation explicitly states carnitine deficiency is iatrogenic, often due to medications like valproic acid, or following bariatric surgery. Supporting documentation should clearly link the deficiency to a specific medical treatment or intervention.

• Ensure documentation specifies the iatrogenic nature; otherwise, consider other carnitine deficiency codes (e.g., E71.40, E71.41).
• Code the underlying cause (e.g., adverse effect of drug, complication of surgery) first, followed by this code.
• Do not use for primary or inherited carnitine deficiencies.
