About coding Hantavirus disease
The ICD-10-CM code for Hantavirus disease is A98.5 (Hemorrhagic fever with renal syndrome). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on A98.5.
Within A98 (other viral hemorrhagic fevers, not elsewhere classified), A98.5 is specifically for hemorrhagic fever with renal syndrome. Related codes cover Crimean-Congo hemorrhagic fever (A98.0), Omsk hemorrhagic fever (A98.1), Kyasanur Forest disease (A98.2), Marburg virus disease (A98.3), Ebola virus disease (A98.4) and other specified viral hemorrhagic fevers (A98.8).
Don't report A98.5 together with the conditions in its Excludes1 note: hantavirus (cardio)-pulmonary syndrome (B33.4).
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.
