About A92.2

A92.2 is the ICD-10-CM diagnosis code for Venezuelan equine fever. It belongs to category A92 (other mosquito-borne viral fevers), 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 A92 (other mosquito-borne viral fevers), A92.2 is specifically for Venezuelan equine fever. Related codes cover Chikungunya virus disease (A92.0), O'nyong-nyong fever (A92.1), West Nile virus infection (A92.3), Rift Valley fever (A92.4), Zika virus disease (A92.5), other specified mosquito-borne viral fevers (A92.8) and mosquito-borne viral fever, unspecified (A92.9).

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 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator, relative weight 5.7444), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC, relative weight 3.9708), DRG 097 (Non-Bacterial Infection of Nervous System Except Viral Meningitis with MCC, relative weight 3.8226), DRG 098 (Non-Bacterial Infection of Nervous System Except Viral Meningitis with CC, relative weight 2.2706) and DRG 099 (Non-Bacterial Infection of Nervous System Except Viral Meningitis without CC/MCC, relative weight 1.5256), in MDC 01 (Diseases and Disorders of the Nervous System), 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 066.2 (Venezuelan equine fever).
