About coding Boyd's dysentery

The ICD-10-CM code for Boyd's dysentery is A03.2 (Shigellosis due to Shigella boydii).

Within A03 (shigellosis), A03.2 is specifically for shigellosis due to Shigella boydii. Related codes cover due to Shigella dysenteriae (A03.0), due to Shigella flexneri (A03.1), due to Shigella sonnei (A03.3), other shigellosis (A03.8) and unspecified (A03.9).

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 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.
