Neuropsychological Testing: How to Bill Correctly for Time and Effort

Neuropsychological testing is a vital tool in healthcare; it helps providers assess cognitive, behavioral, and emotional functioning in patients. These tests are often used to evaluate conditions such as dementia, brain injury, ADHD, and mood disorders. While they are clinically significant, billing for neuropsychological services can be complex. Unlike standard procedures, reimbursement depends heavily on the time spent, type of testing, and the effort required for interpretation, which makes accurate billing essential for both compliance and revenue integrity.
This blog will guide you through the billing process for neuropsychological testing, explain the relevant CPT codes, and offer advice on how to avoid common errors.

Why Accurate Billing for Neuropsychological Testing Matters

Billing for neuropsychological testing is not only about submitting the right codes but also about ensuring that providers are properly reimbursed for the extensive time and expertise required. A neuropsychologist spends hours conducting clinical interviews, administering tests, scoring results, and interpreting findings. If billing is not handled correctly, much of this effort can go unrewarded.

Moreover, insurers, including Medicare and private payers, have strict rules regarding what is billable and what is not. A lack of documentation or incorrect use of CPT codes can lead to denied claims, delayed payments, or compliance risks. By understanding the billing framework, providers can safeguard their revenue while continuing to deliver quality patient care.

Understanding CPT Codes for Neuropsychological Testing

The first step in correct billing is knowing the CPT codes that apply to neuropsychological testing. These codes are divided based on the type of service and the time spent.
  • 96132 and 96133 cover the time a neuropsychologist spends on evaluation services, including reviewing records, integrating patient history, and interpreting test results. Code 96132 is used for the first hour of evaluation, while 96133 is used for each additional hour.
  • 96136 and 96137 are used for test administration and scoring, whether performed by a physician, psychologist, or technician under supervision. Code 96136 applies to the first 30 minutes and 96137 to each additional 30 minutes.
These distinctions may seem technical, but they are the foundation of accurate billing. Missing the correct code or failing to account for all time spent can significantly reduce reimbursement.

Billing for Time and Effort

One of the most challenging aspects of neuropsychological billing is determining what counts as billable time. Face-to-face activities such as clinical interviews and test administration are billable, but so are certain non-face-to-face services like record review and interpretation. The key is to document each segment of time clearly.
For example, a one-hour clinical interview should be billed separately from three hours of test administration and two hours of scoring and interpretation. Without proper documentation, insurers may only reimburse for a portion of the service, even though much more time was invested.
Providers should remember that time-based billing requires accuracy and consistency. Rounding up time or failing to distinguish between face-to-face and non-face-to-face tasks is a common reason for claim denials.

Documentation Guidelines You Should Follow

Insurers demand clear documentation to justify reimbursement for neuropsychological testing. A detailed report should include the reason for referral, patient history, tests administered, time spent on each task, and a summary of findings. The clinical significance of the evaluation should also be explained, as this supports medical necessity.

Accurate documentation not only secures reimbursement but also serves as a safeguard during audits. Medicare and many private payers closely examine claims for neuropsychological testing, so vague or incomplete notes can put your practice at financial and compliance risk.

Common Billing Pitfalls and How to Avoid Them

Billing errors are widespread in neuropsychological testing because of the time-based nature of the codes. Some of the most common mistakes include using the wrong CPT codes, underreporting time, failing to separate evaluation from administration, and overlooking technician involvement.
Another frequent pitfall is ignoring payer-specific rules. For instance, Medicare may reimburse differently than commercial insurers for test scoring performed by technicians. Staying updated with guidelines for each payer is essential to avoid denials and delayed payments.
