ICD-10 code for Bubonic plague

The ICD-10-CM code for Bubonic plague is A20.0 (Bubonic plague).

Within A20 (plague), A20.0 is specifically for Bubonic plague. Related codes cover Cellulocutaneous plague (A20.1), pneumonic plague (A20.2), meningitis (A20.3), Septicemic plague (A20.7), other forms of plague (A20.8) and unspecified (A20.9).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235) and DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
