About K22.6

K22.6 is the ICD-10-CM diagnosis code for Gastro-esophageal laceration-hemorrhage syndrome. It belongs to category K22 (other diseases of esophagus), block K20-K31 (diseases of esophagus, stomach and duodenum) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within K22 (other diseases of esophagus), K22.6 is specifically for Gastro-esophageal laceration-hemorrhage syndrome. Related codes cover Achalasia of cardia (K22.0), ulcer of esophagus (K22.1), esophageal obstruction (K22.2), perforation of esophagus (K22.3), dyskinesia of esophagus (K22.4), diverticulum of esophagus, acquired (K22.5), Barrett's esophagus (K22.7), other specified diseases of esophagus (K22.8) and 1 more.

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 368 (Major Esophageal Disorders with MCC, relative weight 1.6433), DRG 369 (Major Esophageal Disorders with CC, relative weight 0.9922) and DRG 370 (Major Esophageal Disorders without CC/MCC, relative weight 0.6744), 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 530.7 (Gastroesophageal laceration-hemorrhage syndrome).
