Central European tick-borne encephalitis

This code identifies a specific viral infection of the central nervous system transmitted by ticks, endemic to Central Europe. It manifests as an inflammatory condition affecting the brain and/or meninges, caused by the Central European subtype of the tick-borne encephalitis virus.

Assign this code when documentation confirms a diagnosis of tick-borne encephalitis, specifically identified as the Central European variant. This typically follows a history of tick exposure in endemic regions and laboratory confirmation of the specific viral strain.

• Ensure documentation specifies "Central European" to differentiate from other forms of tick-borne encephalitis.
• Do not confuse with other forms of encephalitis or tick-borne diseases without CNS involvement.
• Consider sequencing with codes for neurological manifestations or complications if present.
