Q: What insurances do you accept and do I need a referral?

A: We currently accept BCBS (non-ACA plans), Aetna, Medicare, Tricare, and TriWest. We are working on adding additional insurances; however, please keep in mind that the managed healthcare climate is tremendously dynamic. As such, this list may or may not be accurate depending on contractual changes in managed care. Most plans do not require a referral from a physician; however, obtaining a referral from your PCP, Psychiatrist, Neurologist, or other physician/medical provider is always helpful.

Q: What is the cost of testing?

A: Unfortunately, the total cost of testing is difficult to determine depending on multiple factors such as your insurance contract, co-pay, deductible, co-insurance, and/or the medical necessity of your evaluation (as outlined by your insurance contract). However, we do provide reduced rates for self-pay patients, as well as a sliding scale and limited spots for pro bono appointments. We are committed to transparency when it comes to the cost of your evaluation, and we will always provide flexible payment plans. Lastly, Dr. Armstrong is committed to not allowing health care costs limit access to his services. If you are in need of services, we will do all that we can to help you personally or provide you with a list of referral sources whom we trust. 

Q: What should I expect for an evaluation?

A: You can expect that we are committed to both clinical excellence and approachable/compassionate care. Most evaluations include at least 1 hour with Dr. Armstrong during which time you will review your medical history, symptoms, and medical records. After the interview and depending on the purpose of the evaluation, the patient will undergo testing with either Dr. Armstrong or his assistant Mrs. Trenchard. Testing usually requires between 2-4 hours for a psychological exam and 3-8 hours for a neuropsychological evaluation. If you would like more information concerning the specific time required for your appointment, please call us for additional information. Furthermore, you can also expect that you will be treated warmly and compassionately during the entire process. You are more than a patient to us. We really care about providing you with the highest quality of psychological services so that your life can get better. 

Q: Does Dr. Armstrong prescribe medication?

A: Although he and Dr. Mears have advanced training in psychopharmacology, the state of Texas does not allow psychologists to prescribe medication and/or practice medicine in any form. However, we are happy to provide you with a list of referral sources for potential psychiatric treatment providers. 

Q: Are you accepting new patients for counseling/psychotherapy/ADHD coaching?

A: Currently, we have very limited openings for counseling. However, we are happy to provide you with a list of counselors/psychologists in your area whom we trust. 

Q: My attorney wants me to complete an evaluation with you. Will my insurance pay for it?

A: Unfortunately, any evaluation that you or your attorney are seeking regarding civil or criminal litigation in which you are involved will not typically be covered by health insurance. These evaluations are considered to be "forensic" and will require additional fees. 

Q: Do you provide child custody evaluations?

A: No. Unfortunately, no one in our practice has this training or provides these services. Again, we are happy to provide you with a list of potential referral sources.
