About coding vomiting
The ICD-10-CM code for vomiting is R11.10 (Vomiting, unspecified). The official index lists 26 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R11.10.
Within R11.1, choose R11.10 (unspecified) only when documentation doesn't support a more specific option: without nausea (R11.11), Projectile vomiting (R11.12), of fecal matter (R11.13), 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 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.
