Psychological and Neuropsychological Testing services utilize diagnostic tests when mental illness or brain dysfunction is suspected, and clarification is essential for the diagnosis and treatment. This family of codes was recently revised and extensive changes are scheduled to go into effect on Jan. 1, 2019. However, until Dec. 31, 2018, the existing CPT® codes for psychological testing (96101-96103) and neuropsychological testing (96118-96120) should be used with billing for these services.

2019 changes to psychological and neuropsychological testing codes

As of Jan. 1, 2019 practitioners will need to use the new billing codes for Medicare and all insurance carriers. The list is intended to familiarize you with specific testing coding changes and will be helpful for updating your billing and claims processing systems.

Descriptors for 2019 Psychological & Neuropsychological Assessment CPT Codes for Psychologists (PDF, 37KB).

Given the new modernized coding structure that more accurately describes the work required when multiple hours of technical and professional services are performed, APA has developed three separate crosswalks between the current (2018) testing codes and the corresponding new codes to be used in 2019. These pdfs are intended to assist psychologists as they make the transition.
