ICD-10 code for hematemesis

The ICD-10-CM code for hematemesis is K92.0 (Hematemesis). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K92.0.

Within K92 (other diseases of digestive system), K92.0 is specifically for hematemesis. Related codes cover melena (K92.1), gastrointestinal hemorrhage, unspecified (K92.2), other specified diseases of the digestive system (K92.8) and disease of digestive system, unspecified (K92.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 377 (Gastrointestinal Hemorrhage with MCC, relative weight 1.8127), DRG 378 (Gastrointestinal Hemorrhage with CC, relative weight 0.9732), DRG 379 (Gastrointestinal Hemorrhage without CC/MCC, relative weight 0.6381), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 06 (Diseases and Disorders of the Digestive System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
