Anorexia nervosa, restricting type, unspecified

This code signifies a severe eating disorder characterized by self-starvation and an intense fear of gaining weight, where the individual primarily restricts food intake and does not regularly engage in binge-eating or purging behaviors. The "unspecified" nature indicates that further details regarding the severity or specific subtype of restricting anorexia nervosa are not documented.

Apply this code when documentation clearly states a diagnosis of anorexia nervosa, restricting type, but lacks information on the specific severity (e.g., mild, moderate, severe, extreme). This is appropriate when the clinician has not specified the BMI or other criteria for severity.

• Ensure the documentation explicitly states "restricting type" and not "binge-eating/purging type."
• If severity (e.g., mild, moderate, severe, extreme) is documented, use the more specific F50.01x codes.
• Do not confuse with other eating disorders like bulimia nervosa (F50.2) or other specified feeding or eating disorder (F50.89).
