About coding Oropouche viral fever
The ICD-10-CM code for Oropouche viral fever is A93.0 (Oropouche virus disease).
Within A93 (other arthropod-borne viral fevers, not elsewhere classified), A93.0 is specifically for Oropouche virus disease. Related codes cover Sandfly fever (A93.1), Colorado tick fever (A93.2) and other specified arthropod-borne viral fevers (A93.8).
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 865 (Viral Illness with MCC, relative weight 1.3485) and DRG 866 (Viral Illness without MCC, relative weight 0.8692), 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.
