This document discusses medical codes used for reporting the diagnosis and treatment of epilepsy. It provides codes from the Current Procedural Terminology (CPT) and International Classification of Diseases, Tenth Revision (ICD-10) manuals for common epilepsy-related procedures, tests, and diagnoses. Accurate reporting of these codes is important for clinical documentation, patient care, and medical billing.

Summary – The blog discusses the medical codes used for reporting diagnosis
and treatment of epilepsy.
Medical Codes to Report Epilepsy
A common neurological disorder that can affect men and women of all age
groups, epilepsy is characterized by two or more unprovoked seizures. The
condition occurs due to abnormal brain activity and causes seizures or periods
of unusual behaviour, sensations and sometimes, loss of awareness. Treatment
for this condition involves a combination of medications and surgery.
Neurologists need to carefully understand the medical history of the patient and
assess brain imaging results to analyze the abnormal patterns of electrical
activity in the brain. Specificity in the diagnosis is essential for accurate clinical
documentation and delivering excellent patient care. Medical billing services
can ensure accurate reporting of diagnosis and treatment of this neurological
disorder on claims.
