Polyphagia

This code represents polyphagia, a medical condition characterized by excessive or insatiable appetite and increased food intake. It is often referred to as hyperphagia and is a symptom rather than a standalone disease.

Use this code when documentation indicates a patient is experiencing abnormally increased hunger or food consumption. This symptom is frequently associated with metabolic disorders such as diabetes mellitus, hyperthyroidism, or certain neurological conditions.

• Always code the underlying cause of polyphagia first, if known and documented.
• Do not confuse polyphagia with bulimia nervosa (307.51), which involves binge eating followed by compensatory behaviors.
• Ensure the medical record clearly documents the patient's excessive appetite or food intake to support this diagnosis.
