Frequently Asked Questions
What is a neuropsychological evaluation?
A neuropsychological evaluation is a way to understand how a person's brain is working compared to others of the same age and, when possible, similar educational background. It is a comprehensive process that includes several key components. It begins with a clinical interview, followed by in-person testing sessions, and concludes with a feedback session. The evaluation might also involve reviewing records, observing the individual in a school setting, and working with teachers and medical providers. Additionally, self, parent, and teacher questionnaires may be completed. Some tests are conducted electronically using an iPad, laptop or virtual reality headset, while others are done with paper and pencil. Throughout the entire evaluation, Dr. Hoffmann and/or Dr. Kirchgaesser are present with the examinee to provide support and guidance.
When should you consider a neuropsychological evaluation?
A neuropsychological evaluation is usually recommended when someone notices changes in their thinking or memory, often after an illness or injury. For children, these evaluations are often done if they're struggling to meet grade-level expectations or if there's a sudden drop in their school performance.
How much time is needed for a neuropsychological evaluation?
Depending on the purpose and type of evaluation, you can expect about 4 to 8 hours of in-person testing. Each evaluation also includes a one-hour clinical interview and a 90-minute feedback session. Additionally, child-friendly feedback sessions are available.
How much does an evaluation cost?
The price of an evaluation includes all parts of the process, from beginning to end. This covers the clinical interview, in-person testing sessions, data analysis, collaboration with other professionals like teachers, therapists, and tutors, report writing, and the feedback session. Evaluations with Dr. Hoffmann cost between $5,600 and $7,200, while those with postdoctoral fellow Dr. Katrina Kirchgaesser range from $4,600 to $6,000.
Do you take insurance?
Dr. Hoffmann isn't part of any insurance networks right now, but she will provide you with the paperwork needed to submit to your insurance company for possible reimbursement through your out-of-network benefits after the evaluation. It's a good idea to contact your insurance company before the evaluation to check your plan's coverage and out-of-network benefits. If you're working with Dr. Hoffmann, ask your insurance about these testing codes: 90791, 96132, 96133, 96136, and 96137. If you're working with postdoctoral fellow Dr. Katrina Kirchgaesser, inquire about codes 90791, 96132, 96133, 96138, and 96139.
How long does it take to get the results from the evaluation?
Feedback sessions are usually scheduled about 2-3 weeks after the last testing session. You'll typically receive the report within 1-2 weeks after the feedback session. Overall, the whole process—from the initial intake session to the completed report—usually takes about 4 to 6 weeks.
How will I know which type of evaluation is appropriate for me, my child or my loved one?
Before setting up your first in-person appointment, Dr. Hoffmann will talk with you about the details of your situation to help decide which evaluation is best for you.
