From the official ICD-10-CM alphabetic index entry “Enteropathy”. Page updated September 29, 2026.
About coding enteropathy
The ICD-10-CM code for enteropathy is K63.9 (Disease of intestine, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K63.9.
Within K63, choose K63.9 (Disease of intestine, unspecified) only when documentation doesn't support a more specific option: abscess of intestine (K63.0), perforation of intestine (nontraumatic) (K63.1), fistula of intestine (K63.2), ulcer of intestine (K63.3), Enteroptosis (K63.4), polyp of colon (K63.5) and other specified diseases of intestine (K63.8).
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 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228) and DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), 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.
