What This Code Means

Rumination disorder in adults is a condition where a person repeatedly regurgitates food that has already been swallowed, re-chews it, and either swallows it again or spits it out.

Coding Tips

  • Ensure the rumination is not secondary to another medical condition like GERD or gastroesophageal reflux; rule out organic causes first
  • This code applies to adults; rumination disorder in children uses a different code (F98.8)

Clinical Significance

Rumination disorder in adults involves the repeated regurgitation of food for at least one month, which may be re-chewed, re-swallowed, or spit out. This is not due to gastrointestinal disease or another eating disorder. In adults, it is often underdiagnosed and can cause significant complications including malnutrition, weight loss, dental erosion, and esophageal damage.

Documentation Requirements

  • Documentation of repeated regurgitation of food over at least one month
  • Evidence that regurgitation is not due to a gastrointestinal condition (GERD, pyloric stenosis, etc.)
  • Not occurring exclusively during anorexia nervosa, bulimia nervosa, binge eating disorder, or ARFID
  • Provider explicitly documenting rumination disorder diagnosis
  • Assessment of nutritional status and associated complications

Excludes 1 — Do NOT code together

  • rumination disorder in infancy and childhood (F98.21)
