Lissencephaly is a rare brain malformation characterized by smooth brain surface due to abnormal neuronal migration during fetal development. The ICD-10 code for lissencephaly is Q04.3. In the previous coding system, ICD-9, it was classified under code 742.2. Lissencephaly can lead to severe developmental delays, intellectual disabilities, and neurological impairments.
Lissencephaly is a rare genetic disorder characterized by the absence or underdevelopment of brain folds, resulting in a smooth brain surface. The International Classification of Diseases, Tenth Revision (ICD-10), provides a specific code for this condition. The ICD-10 code for lissencephaly is Q04.3.
Prior to the implementation of ICD-10, the International Classification of Diseases, Ninth Revision (ICD-9) was used. The corresponding code for lissencephaly in ICD-9 is 742.2. It is important to note that ICD-9 codes are no longer in use, as they have been replaced by the more comprehensive ICD-10 coding system.
Lissencephaly is a complex condition that affects brain development and can lead to severe neurological impairments. It is typically diagnosed in infancy or early childhood and is associated with developmental delays, intellectual disabilities, seizures, and other neurological abnormalities.
Accurate coding of medical conditions is crucial for healthcare providers, researchers, and insurers to track and analyze disease patterns, treatment outcomes, and healthcare resource utilization. The ICD-10 code Q04.3 provides a standardized way of identifying and classifying lissencephaly, facilitating better understanding and management of this condition.
