About coding gluten intolerance
The ICD-10-CM code for gluten intolerance is K90.41 (Non-celiac gluten sensitivity).
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.
