K22.6 is a billable ICD-10-CM diagnosis code for gastro-esophageal laceration-hemorrhage syndrome. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 368 through 370. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 75 closely related codes. Coders also document this condition as laceration of esophagus. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Esophageal disorders and Gastrointestinal hemorrhage.
