G93.81

What This Code Means

Temporal sclerosis is a condition where brain tissue in the temporal lobe (the area near the temples) becomes scarred and hardened. This condition is often associated with epilepsy and can cause seizures.

Coding Tips

• •Verify whether this is mesial temporal sclerosis (MTS) or another type, as this distinction may affect treatment planning and should be documented by the physician
• •When temporal sclerosis is associated with epilepsy, code both G93.81 and the appropriate epilepsy code (G40.x series) to capture the complete clinical picture
