P92.1 is a billable ICD code used to specify a diagnosis of regurgitation and rumination of newborn. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code P921 is used to code Rumination syndrome

Rumination syndrome, or Merycism, is an under-diagnosed chronic motility disorder characterized by effortless regurgitation of most meals following consumption, due to the involuntary contraction of the muscles around the abdomen. There is no retching, nausea, heartburn, odour, or abdominal pain associated with the regurgitation, as there is with typical vomiting. The disorder has been historically documented as affecting only infants, young children, and people with cognitive disabilities (the prevalence is as high as 10% in institutionalized patients with various mental disabilities). Today it is being diagnosed in increasing numbers of otherwise healthy adolescents and adults, though there is a lack of awareness of the condition by doctors, patients and the general public.

Specialty: Psychiatry
MeSH Code: D019959
ICD 9 Code: 307.53

A postprandial manometry of a patient with rumination syndrome showing intra-abdominal pressure. The "spikes" are characteristic of the abdominal wall contractions responsible for the regurgitation in rumination.
