Relatively undervalued: Comparing the work relative value units of neuropsychological evaluation to other services.

Abstract

Objective: We examined work relative value units (wRVUs) and associated revenue of current procedural terminology (CPT) codes for evaluation and management (E&M) services, neuropsychological evaluation (NPE), psychological evaluation (PE), and psychotherapy. Method: CPT code wRVUs were aggregated for E&M (99202-99215), NPE (96116, 96132, 96133, 96136, and 96137), PE (90791, 96130, 96131, 96136, and 96137), and psychotherapy (90791 and 90832-90837 with and without the complexity modifier, 90785). Per minute wRVUs were calculated for each CPT code. The Centers for Medicare and Medicaid Services 2023 conversion factor ($33.8872) was multiplied by wRVUs to examine reimbursement per hour and per prototypical four-hour clinic slot. Results: The wRVUs per minute showed the following ranges: 0.032-0.07 for E&M services, 0.015-0.063 for NPE, 0.015-0.124 for PE, and 0.043-0.135 for psychotherapy. Average hourly revenue ranged from $72 for NPE to $132 for psychotherapy with the complexity modifier. Revenue for prototypical four-hour clinics ranged from $283 for NPE to $493 for psychotherapy with the complexity modifier. PE and psychotherapy services were valued at 124-184% of NPE. Conclusions: E&M code wRVUs increase with case complexity reflecting greater work intensity, and a modifier to PE and psychotherapy captures additional effort needed in complex cases. In contrast, NPE codes lack a complexity modifier, and NPE wRVUs are lower than those of PE and psychotherapy, the latter of which can be billed by master's level providers. NPE is undervalued compared to PE and psychotherapy based on wRVUs currently assigned to the CPT codes used for the respective services.
