What This Code Means

A feeding disorder in infants and young children characterized by repeated regurgitation and rechewing of food that has already been swallowed, without nausea or gastrointestinal disease.

Coding Tips

  • This diagnosis requires documentation that the behavior is not due to GERD, pyloric stenosis, or other medical conditions
  • Typically diagnosed in children ages 3 months to 2 years; document the child's age and developmental context

Clinical Significance

Rumination disorder of infancy and childhood involves repeated regurgitation and re-chewing of food that is not attributable to gastrointestinal or other medical conditions. In infants, it can lead to failure to thrive, malnutrition, and death if untreated. In older children, it causes significant nutritional and dental complications. This behavioral feeding disorder requires multidisciplinary management including behavioral therapy and nutritional support.

Documentation Requirements

  • Provider documentation of rumination disorder diagnosis
  • Evidence of repeated regurgitation of food over at least one month
  • Documentation that the behavior is not due to a gastrointestinal condition (e.g., GERD, pyloric stenosis)
  • Documentation that the behavior does not occur exclusively during an eating disorder (anorexia nervosa, bulimia)
  • Nutritional assessment, growth parameters, and treatment plan including behavioral intervention
