About coding peristalsis
The ICD-10-CM code for peristalsis is R19.2 (Visible peristalsis).
Within R19 (other symptoms and signs involving the digestive system and abdomen), R19.2 is specifically for visible peristalsis. Related codes cover intra-abdominal and pelvic swelling, mass and lump (R19.0), abnormal bowel sounds (R19.1), abdominal rigidity (R19.3), change in bowel habit (R19.4), other fecal abnormalities (R19.5), Halitosis (R19.6), diarrhea, unspecified (R19.7) and other specified symptoms and signs involving the digestive system and abdomen (R19.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
