About coding Pseudotuberculosis
The ICD-10-CM code for Pseudotuberculosis is A28.2 (Extraintestinal yersiniosis). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on A28.2.
Within A28 (other zoonotic bacterial diseases, not elsewhere classified), A28.2 is specifically for Extraintestinal yersiniosis. Related codes cover Pasteurellosis (A28.0), Cat-scratch disease (A28.1), other specified zoonotic bacterial diseases, not elsewhere classified (A28.8) and zoonotic bacterial disease, unspecified (A28.9).
Don't report A28.2 together with the conditions in its Excludes1 note: enteritis due to Yersinia enterocolitica (A04.6) and plague (A20.-).
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.
