Simple febrile convulsions

This code represents a seizure occurring in a child, typically between 6 months and 5 years of age, that is associated with a fever but without evidence of intracranial infection or other defined cause. These seizures are generalized, brief, and do not recur within 24 hours or during the same febrile illness.

Use this code when documentation clearly indicates a first-time or recurrent simple febrile seizure in a pediatric patient. This diagnosis is supported by the absence of neurological deficits, a normal post-ictal state, and no history of afebrile seizures.

• Do not use this code for complex febrile seizures (e.g., prolonged, focal, or multiple within 24 hours).
• Ensure documentation rules out meningitis, encephalitis, or other central nervous system infections.
• This code is typically a primary diagnosis unless a more specific underlying febrile illness (e.g., otitis media) is also coded.
