About coding babesiosis

The ICD-10-CM code for babesiosis is B60.00 (Babesiosis, unspecified). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B60.00.

Within B60.0, choose B60.00 (unspecified) only when documentation doesn't support a more specific option: due to Babesia microti (B60.01), due to Babesia duncani (B60.02), due to Babesia divergens (B60.03) and other babesiosis (B60.09).

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 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.
