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

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.

Time is money: Examining the time cost and associated charges of common performance validity tests

Objective: This study presents data on the time cost and associated charges for common performance validity tests (PVTs). It also applies an approach from cost effectiveness research to comparison of tests that incorporates cost and classification accuracy. Method: A recent test usage survey was used to identify PVTs in common use among adult neuropsychologists. Data on test administration and scoring time were aggregated. Charges per test were calculated. A cost effectiveness approach was applied to compare pairs of tests from three studies using data on test administration time and classification accuracy operationalized as improvement in posterior probability beyond base rate. Charges per unit increase in posterior probability over base rate were calculated for base rates of invalidity ranging from 10 to 40%. Results: Ten commonly used PVTs measures showed a wide range in test administration and scoring time from 1 to 3 minutes to over 40 minutes with associated charge estimates from $4 to $284. Cost effectiveness comparisons illustrated the nuance in test selection and benefit of considering cost in relation to outcome rather than prioritizing time (i.e. cost minimization) classification accuracy alone. Conclusions: Findings extend recent research efforts to fill knowledge gaps related to the cost of neuropsychological evaluation. The cost effectiveness approach warrants further study in other samples with different neuropsychological and outcome measures.

Embedded cognitive and emotional/affective self-reported symptom validity indices on the patient competency rating scale

OBJECTIVE

Although there is an abundance of research on stand-alone and embedded performance validity tests and stand-alone symptom validity tests (SVTs), less emphasis has been placed on embedded SVTs. The goal of the current study was to examine the ability of embedded indicators within the Patient Competency Rating Scale (PCRS) to separately detect invalid cognitive and/or emotional/affective symptom responding.

METHOD

Participants included 299 veterans assessed in a VA medical center epilepsy monitoring unit from 2013-2017 (mean age = 48.8 years, SD = 13.5 years). Two SVT composites were created; self-reported cognitive symptom validity (SVT-C) and self-reported emotional/affective symptom validity (SVT-E). Groups were compared on PCRS total and index scores (i.e., cognitive, activities of daily living, emotional, and interpersonal competencies) using ANOVAs. Receiver operating characteristic (ROC) curve analyses assessed the classification accuracy of the PCRS total and index scores for SVT-C and SVT-E.

RESULTS

In ANOVAs, SVT-C was significantly associated with all PCRS indices, while SVT-E was only significantly associated with the PCRS total, emotional, and interpersonal competency indices. Although the PCRS-T ≤ 90 had the strongest classification of SVT-C and SVT-E (specificities: .90, sensitivities: .44 to .50), PCRS index scores showed suggestive evidence of domain specificity, with PCRS-ADL ≤22, PCRS-C ≤ 20, and PCRS-CADL ≤45 best classifying SVT-C (specificities: .92, sensitivities: .33) and the PCRS-E ≤ 18 best classifying the SVT-E group (specificity: .93, sensitivity: .40).

CONCLUSION

Results suggest the PCRS may be used to obtain clinically useful information while including embedded indicators that can assess cognitive and/or emotional/affective symptom invalidity.

Integrating Neuropsychology into Interprofessional Geriatrics Clinics

Interprofessional healthcare teams are increasingly viewed as a clinical approach to meet the complex medical, psychological, and psychosocial needs of older adult patients. Despite the fact that older adults are at risk for cognitive difficulties, neuropsychologists are not routinely included on Geriatrics consult teams. The primary aim of this paper is to highlight the utility of neuropsychology within an interprofessional Geriatrics consult clinic. To address this aim, we describe specific benefits to patient care that may be associated with the inclusion of neuropsychologists on Geriatrics consult teams, including differential diagnosis, enhanced patient care, and reduced barriers to care. We provide a description of the integration of neuropsychology within a Veterans Health Administration (VA) interprofessional Geriatrics consult clinic team in order to illustrate the implementation of this model.

Return on Investment and Value Research in Neuropsychology: A Call to Arms†

There is substantial empirical evidence to support the clinical value of neuropsychological evaluation and the incremental value of neuropsychological assessment, suggesting such evaluation is beneficial in the prediction and management of clinical outcomes. However, in the cost-conscious and evolving era of healthcare reform, neuropsychologists must also establish the economic value, or return on investment, of their services. There is already a modest body of literature that demonstrates the economic benefits of neuropsychological evaluation, which is reviewed in the current paper. Neuropsychologists will need to be able to communicate, and develop evidence of, economic value of their services; thus, this paper also discusses common concepts, terms, and models used in healthcare valuation studies. Finally, neuropsychologists are urged to incorporate these financial concepts in their clinical practice and research.
