About coding digestive problem
The ICD-10-CM code for digestive problem is K92.9 (Disease of digestive system, unspecified).
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.
