About coding Salmonellosis
The ICD-10-CM code for Salmonellosis is A02.0 (Salmonella enteritis).
Within A02 (other salmonella infections), A02.0 is specifically for salmonella enteritis. Related codes cover salmonella sepsis (A02.1), localized salmonella infections (A02.2), other specified salmonella infections (A02.8) and salmonella infection, unspecified (A02.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 371 (Major Gastrointestinal Disorders and Peritoneal Infections with MCC, relative weight 1.7089), DRG 372 (Major Gastrointestinal Disorders and Peritoneal Infections with CC, relative weight 0.9964) and DRG 373 (Major Gastrointestinal Disorders and Peritoneal Infections without CC/MCC, relative weight 0.6941), 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.
