In simple words: This code describes a newborn baby who spits up or brings food back up and chews it again.It's a specific problem with feeding that happens only in very young babies.

This ICD-10-CM code, P92.1, specifically identifies regurgitation and rumination as a feeding problem in a newborn.Regurgitation refers to the passive return of stomach contents into the esophagus and mouth, while rumination involves the repeated regurgitation and rechewing of food.This code is applied only to newborns (within the first 28 days of life) and should not be used for older infants or children.The diagnosis requires clinical evaluation to distinguish it from other gastrointestinal issues.

Example 1: A newborn infant presents with frequent spitting up of milk after feedings, without any evidence of distress or weight loss.The pediatrician diagnoses regurgitation., A 10-day-old infant is observed to repeatedly bring up partially digested food and chew it again. This is accompanied by some weight loss and the pediatrician diagnoses rumination., A newborn presents with both regurgitation and rumination, resulting in poor weight gain and requiring close monitoring and possible intervention.

Detailed documentation should include the frequency, volume, and character of the regurgitated or ruminated material; the infant's weight and growth parameters; the feeding pattern (breastfeeding or bottle-feeding, type of formula, etc.); any associated symptoms (e.g., vomiting, diarrhea, abdominal distension, irritability); and the physician's assessment and plan of care.

** The distinction between regurgitation and vomiting is important.Vomiting is a forceful expulsion of stomach contents, whereas regurgitation is a passive reflux.This code is not appropriate for cases of forceful vomiting.Always review the full clinical picture to ensure accurate coding.
