#Dsm 5 anorexia code
One obvious criticism of ICD-10 is the absence of a unique code for and recognition of binge eating disorder as a distinct eating disorder-given that it is the most common eating disorder and is associated with significant comorbidities and impairment. The differences across eating disorder diagnoses in DSM-5 and ICD-10 complicate the work of clinicians. In ICD-10, diagnoses of atypical anorexia nervosa (F50.1) and atypical bulimia nervosa (F50.3) are specified as unique disorders, but any other eating disorder may receive the code of F50.8 for other eating disorders. In addition, purging disorder (ie, recurrent purging in the absence of bingeing) and night eating syndrome (ie, recurrent episodes of consciously eating at night) may be specified under an OSFED diagnosis. This includes individuals who may not meet the weight threshold for anorexia nervosa, or the frequency and duration of bulimia nervosa or binge eating disorder. In DSM-5, individuals who meet significant criteria for an eating disorder but do not meet criteria for 1 of the 3 disorders described above may receive a diagnosis of other specified feeding and eating disorder, or OSFED.

Anorexia nervosa is divided into 2 subtypes:

1 ICD-10, however, still acknowledges that amenorrhea may be present in females with anorexia nervosa. Moreover, the presence of amenorrhea does not differentiate severity of psychopathology. One major change in DSM-5 is the removal of the amenorrhea criterion, which was criticized for not being applicable to males or prepubescent females. ICD-10 (F50.0) quantifies low weight as at least 15% below what is expected or a BMI of 17.5 or lower.Ĭriteria from DSM-5 and ICD-10 recognize a fear of gaining weight and significant body image disturbance as essential features. Previously, the weight criteria were criticized for being arbitrary because the criterion of 15% below ideal body weight was not empirically derived. Severity level may be assigned based on specified BMI. DSM-5 criteria for low weight consider what is “normal” for one’s age, sex, physical health, and developmental trajectory. However, the level at which body weight is considered “significantly low” has evolved. The key clinical criterion in anorexia nervosa is a significantly low body weight. Many applaud the recognition of binge eating disorder in DSM-5 as a major improvement in the field, but it does not have its own code in ICD-10.Īnorexia nervosa was first included in DSM-III and ICD-9. Moreover, diagnosis is further complicated by the differences in criteria outlined in DSM-5 and ICD-10 ( Table). Although efforts have been made to improve the diagnostic criteria, not all presentations fit perfectly into the established criteria. Clinicians are faced with the difficulty of determining the presenting problem and identifying the appropriate diagnostic code needed for insurance billing. It is essential to detect the presence of an eating disorder because of high associated mortality.
