About coding Korean hemorrhagic fever
The ICD-10-CM code for Korean hemorrhagic fever is A98.5 (Hemorrhagic fever with renal syndrome).
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.
