Code Description

ICD-10 R56.0 is a billable code used to indicate a diagnosis of febrile convulsions.

Key Diagnostic Point:

Febrile convulsions are seizures that occur in young children, typically between the ages of 6 months and 5 years, triggered by fever. These seizures are generally brief, lasting less than 15 minutes, and can be either generalized or focal. The fever associated with febrile convulsions is often due to viral infections, such as influenza or roseola, but can also be caused by bacterial infections. The clinical presentation includes loss of consciousness, muscle rigidity, and jerking movements. Importantly, febrile convulsions are usually benign and do not lead to long-term neurological damage. However, they can be distressing for parents and caregivers. Diagnosis is primarily clinical, based on the history of fever and seizure activity, and may be supported by laboratory tests to rule out other causes of seizures. It is crucial to differentiate febrile convulsions from other seizure types, particularly in cases where the child has a history of epilepsy or if the seizure occurs without a fever.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of febrile convulsions, improving the accuracy of data collection and analysis. This specificity helps in understanding the epidemiology of febrile convulsions and their management.

Frequently Asked Questions

What age group is most affected by febrile convulsions?

Febrile convulsions most commonly affect children between the ages of 6 months and 5 years.

Are febrile convulsions a sign of epilepsy?

No, febrile convulsions are typically benign and do not indicate an increased risk of developing epilepsy later in life.
