About the GZB Code Range

The ICD-10-PCS root operation Electroconvulsive Therapy (GZB) refers to a controlled procedure used primarily in mental health treatment to induce seizures electrically. This approach is applied to manage certain psychiatric conditions when other treatments are ineffective.

Within the Mental Health classification, Electroconvulsive Therapy codes detail how the procedure is performed and its specifics. For example, code GZB0ZZZ represents a unilateral, single-seizure treatment where the electrical stimulus is applied to one side of the brain. Code GZB2ZZZ covers a bilateral, single-seizure method involving both sides of the brain. Additionally, GZB4ZZZ includes other forms of electroconvulsive therapy that may not fall neatly into unilateral or bilateral categories. These codes help clinicians accurately document the type of electroconvulsive therapy administered, ensuring precise medical records and billing for mental health services.
