About coding fecal matter vomiting
The ICD-10-CM code for fecal matter vomiting is R11.13 (Vomiting of fecal matter).
Within R11.1 (vomiting), R11.13 is specifically for vomiting of fecal matter. Related codes cover unspecified (R11.10), without nausea (R11.11), Projectile vomiting (R11.12), Bilious vomiting (R11.14), Cyclical vomiting syndrome unrelated to migraine (R11.15) and cannabis hyperemesis syndrome (R11.16).
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 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228) and DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), 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.
