Question

PROVIDE ICD 10 CODE. MAKE SURE IT IS ICD 10 CODE.

A 16-year-old female is admitted to the eating disorders/psychiatric unit of the University Hospital for anorexia nervosa. The patient’s current weight is less than 80% of her expected weight for height and age, and her body mass index (BMI) is 18.2. A thorough history, physical and psychological examination is performed. It is determined the patient has “restricting” subtype of anorexia nervosa, because she loses weight by use of caloric restriction accompanied by excessive exercise. The patient is known to “fast” two days a week to “cleanse her system of food toxins”. The patient is extremely reluctant to gain even a small amount of weight. Intensive medical and psychological support was given to the patient. Weight restoration to 90% of her predicted weight was her primary treatment goal. After admission, laboratory tests revealed a serious electrolyte imbalance, which was treated. Along with medical and psychological support, the patient established a positive relationship with a young dietician who gained the patient’s trust and respect, and this was extremely positive in helping the patient regain control of her disease. The patient was discharged on day 8 with a small weight gain recorded. The patient was transferred to a residential treatment facility with successful eating disorders management program for further care.
