About coding eltor cholera
The ICD-10-CM code for eltor cholera is A00.1 (Cholera due to Vibrio cholerae 01, biovar eltor).
Within A00 (cholera), A00.1 is specifically for cholera due to Vibrio cholerae 01, biovar eltor. Related codes cover due to Vibrio cholerae 01, biovar cholerae (A00.0) and unspecified (A00.9).
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.
