About K90.41

K90.41 is the ICD-10-CM diagnosis code for Non-celiac gluten sensitivity. 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 K90.4 (other malabsorption due to intolerance), K90.41 is specifically for Non-celiac gluten sensitivity. Related codes cover malabsorption due to intolerance, not elsewhere classified (K90.49).

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 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 was added in FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as 579.8 (other specified intestinal malabsorption).
