B96.83Acinetobacter baumannii as the cause of diseases classified elsewhere

B96.83 is the ICD-10-CM diagnosis code for Acinetobacter baumannii as the cause of diseases classified elsewhere. It belongs to category B96 (other bacterial agents as the cause of diseases classified elsewhere), block B95-B97 (bacterial and viral infectious agents) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within B96.8 (other specified bacterial agents as the cause of diseases classified elsewhere), B96.83 is specifically for Acinetobacter baumannii as the cause of diseases classified elsewhere. Related codes cover Helicobacter pylori [H. pylori] as the cause of diseases classified elsewhere (B96.81), vibrio vulnificus as the cause of diseases classified elsewhere (B96.82) and other specified bacterial agents as the cause of diseases classified elsewhere (B96.89).

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 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.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It was added in FY2024, effective October 1, 2023.
