Binge Eating Disorder does not have a specific code in ICD-10-AM. It is typically coded under F50.8 "Other eating disorders." It has its own distinct diagnosis in DSM-5-TR and ICD-11.

Clinical Documentation Notes

Note that Binge Eating Disorder, recognised in DSM-5-TR as a distinct diagnosis, does not have a specific code in ICD-10-AM (use F50.8). ARFID (Avoidant/Restrictive Food Intake Disorder) from DSM-5-TR is also coded under F50.8 in ICD-10-AM. Monitor physical health markers including BMI, electrolytes, and ECG.
