About coding Venezuelan equine encephalitis

The ICD-10-CM code for Venezuelan equine encephalitis is A92.2 (Venezuelan equine fever).

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.
