About K92.9

K92.9 is the ICD-10-CM diagnosis code for disease of digestive system, unspecified. It belongs to category K92 (other diseases of digestive system), 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 K92, choose K92.9 (Disease of digestive system, unspecified) only when documentation doesn't support a more specific option: hematemesis (K92.0), melena (K92.1), gastrointestinal hemorrhage, unspecified (K92.2) and other specified diseases of the digestive system (K92.8).

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.

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 569.9 (unspecified disorder of intestine).
