Anorexia nervosa, restricting type, in remission

This code signifies a patient with a history of anorexia nervosa, characterized by severe restriction of food intake and significantly low body weight, who is currently in a state of remission. Remission implies that the diagnostic criteria for anorexia nervosa are no longer fully met, though the patient may still be vulnerable to relapse.

Use this code when documentation indicates a previous diagnosis of restricting type anorexia nervosa and the patient is no longer exhibiting active symptoms or meeting full diagnostic criteria. This is appropriate for follow-up visits where the patient is stable and maintaining recovery, or for documenting a past medical history of the condition.

• Ensure documentation explicitly states "in remission" or similar language indicating resolution of active symptoms.
• Do not use this code for active anorexia nervosa; refer to F50.01 for active restricting type.
• Consider co-reporting codes for any residual psychological or physical complications if still present and being treated.
