ICD10 code of Avoidant / Restrictive Food Intake Disorder (ARFID) and ICD9 code

Avoidant/Restrictive Food Intake Disorder (ARFID) is classified under the ICD-10-CM code F50.82. While there is no direct equivalent in the older ICD-9-CM system, cases were historically coded under "Feeding disorder of infancy or childhood" (307.59), though these diagnoses lack the clinical specificity of modern ARFID criteria.

What is the clinical definition of ARFID?

Avoidant/Restrictive Food Intake Disorder (ARFID) is a serious feeding and eating disorder characterized by a persistent failure to meet nutritional or energy needs. Unlike other eating disorders, Avoidant/Restrictive Food Intake Disorder (ARFID) is not driven by body image distress or a desire for weight loss. Instead, individuals experience severe sensory sensitivities, fear of aversive consequences (like choking or vomiting), or a general lack of interest in eating.

How is Avoidant/Restrictive Food Intake Disorder (ARFID) diagnosed?

Diagnosis requires a comprehensive assessment by a multidisciplinary team. Clinicians look for specific clinical markers to distinguish Avoidant/Restrictive Food Intake Disorder (ARFID) from typical picky eating:

• Significant weight loss or failure to achieve expected weight gain.


• Significant nutritional deficiency requiring oral or enteral supplements.


• Dependence on enteral feeding or oral nutritional supplements.


• Marked interference with psychosocial functioning due to food avoidance.

Is Avoidant/Restrictive Food Intake Disorder (ARFID) hereditary?

Research suggests that Avoidant/Restrictive Food Intake Disorder (ARFID) has a significant genetic component, often co-occurring with anxiety disorders, autism spectrum disorder, or sensory processing differences. While there is no single "ARFID gene," family history of eating disorders or anxiety often correlates with a higher risk for developing the condition.
