The ICD-10 code for Hemimegalencephaly is Q04.3, while the corresponding ICD-9 code is 742.3. Hemimegalencephaly is a rare neurological disorder characterized by abnormal brain development, resulting in one hemisphere of the brain being larger than the other. It can cause seizures, developmental delays, and intellectual disabilities. Proper diagnosis and coding are crucial for accurate medical records and effective treatment planning.
Hemimegalencephaly is a rare neurological condition characterized by abnormal brain development, resulting in one hemisphere of the brain being significantly larger than the other. This condition is typically present at birth and can lead to various neurological symptoms such as seizures, developmental delays, intellectual disabilities, and motor impairments.
In the International Classification of Diseases, 10th Revision (ICD-10), the specific code for Hemimegalencephaly is Q04.3. This code falls under the category of "Congenital malformations of the nervous system" and further specifies the particular condition affecting brain development.
In the previous version of the classification system, the ICD-9 code for Hemimegalencephaly was 742.3. ICD-9 codes were used prior to the implementation of ICD-10 and have since been replaced to provide a more detailed and comprehensive classification of diseases and conditions.
It's essential to consult with a healthcare professional or medical coding specialist for accurate coding information and to ensure proper documentation for medical records and billing purposes.
