ICD-10 code for gastrointestinal hypersensitive

The ICD-10-CM code for gastrointestinal hypersensitive is K52.29 (Other allergic and dietetic gastroenteritis and colitis). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K52.29.

Within K52.2, choose K52.29 (Other allergic and dietetic gastroenteritis and colitis) only when documentation doesn't support a more specific option: food protein-induced enterocolitis syndrome (K52.21) and food protein-induced enteropathy (K52.22).

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.
