About coding Kreotoxism
The ICD-10-CM code for Kreotoxism is A05.9 (Bacterial foodborne intoxication, unspecified).
Within A05, choose A05.9 (Bacterial foodborne intoxication, unspecified) only when documentation doesn't support a more specific option: foodborne staphylococcal intoxication (A05.0), botulism food poisoning (A05.1), foodborne Clostridium perfringens [Clostridium welchii] intoxication (A05.2), foodborne Vibrio parahaemolyticus intoxication (A05.3), foodborne Bacillus cereus intoxication (A05.4), foodborne Vibrio vulnificus intoxication (A05.5) and other specified bacterial foodborne intoxications (A05.8).
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 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.
