About A98.5
A98.5 is the ICD-10-CM diagnosis code for hemorrhagic fever with renal syndrome. It belongs to category A98 (other viral hemorrhagic fevers, not elsewhere classified), block A90-A99 (arthropod-borne viral fevers and viral hemorrhagic fevers) 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 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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 689 (Kidney and Urinary Tract Infections with MCC, relative weight 1.1415) and DRG 690 (Kidney and Urinary Tract Infections without MCC, relative weight 0.801), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 078.6 (hemorrhagic nephrosonephritis).
