CPT code 61531 is for placing strip electrodes in the brain via small holes to monitor seizures over an extended period.
CPT code 61531 is used to describe the surgical procedure of implanting strip electrodes beneath the dura mater, which is the outermost membrane covering the brain. This is done through one or more small openings in the skull, known as burr or trephine holes. The purpose of this procedure is to facilitate long-term monitoring of seizures, allowing healthcare providers to gather detailed information about the electrical activity in the brain over an extended period. This data is crucial for diagnosing and managing epilepsy and other seizure disorders.
