About K90.0
K90.0 is the ICD-10-CM diagnosis code for celiac disease. It belongs to category K90 (intestinal malabsorption), block K90-K95 (other diseases of the digestive system) 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 K90 (intestinal malabsorption), K90.0 is specifically for celiac disease. Related codes cover tropical sprue (K90.1), blind loop syndrome, not elsewhere classified (K90.2), pancreatic steatorrhea (K90.3), other malabsorption due to intolerance (K90.4), other intestinal malabsorption (K90.8) and unspecified (K90.9).
Use an additional code for associated disorders including: dermatitis herpetiformis (L13.0) and gluten ataxia (G32.81).
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.
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 579.0 (celiac disease).
