Psychological testing is a vital service within mental and behavioral healthcare. It helps clinicians diagnose mental health disorders, determine cognitive functioning, and develop treatment plans. Accurate billing for these services ensures timely reimbursement and prevents claim denials. This guide provides a comprehensive overview of billing practices for psychological testing, including applicable CPT codes, documentation requirements, payer-specific considerations, and real-world applications.
Crisis situations often require immediate care and time-based billing. If you’re unsure how to document and code those sessions, this resource on billing CPT codes 90839 and 90840 for crisis intervention explains what’s required and how to avoid underbilling.
What Is Psychological Testing?
Psychological testing involves the use of standardized instruments to assess various aspects of a patient’s mental health. These may include cognitive ability, personality traits, emotional functioning, and neuropsychological status. It differs from psychotherapy in its focus on measurement and evaluation. Testing may be used for diagnostic clarification, treatment planning, and educational accommodations.
North Carolina Mental Health Billing Tip:
NC Medicaid uses the NCTracks system, which requires accurate service location coding. Billing the wrong place of service (POS) is a common denial reason—especially for telehealth. Check out our North Carolina Billing Service page to avoid denials and streamline payments.

To ensure reimbursement, proper documentation must include:
- Referral reason or clinical question

- Type and number of tests administered
- Time spent on administration, scoring, and interpretation
- Summary of results and clinical impressions
- Diagnostic conclusions and treatment recommendations
The documentation must support the necessity of testing and reflect each component billed.
Who Can Bill for Psychological Testing?
Billing eligibility varies by code and payer. Typically:
- 96130–96131 are billed by licensed psychologists, psychiatrists, or neuropsychologists.
- 96136–96139 may be billed by technicians under supervision.

Best Practices to Avoid Denials
- Verify prior authorization and coverage before testing.
- Use the appropriate mix of codes (e.g., don’t bill 96130 without corresponding administration codes).
- Document start/end times and justify medical necessity.
- Avoid billing when services are solely educational or for non-clinical purposes.
- Review payer-specific guidelines; for example, some insurers require time logs for each session.
Insurance Variability
Medicare
- Covers testing when medically necessary and ordered by a qualified provider.
- Documentation must support diagnostic needs and show how results will influence treatment.
Medicaid
- Varies by state; some require pre-authorization or limit the number of hours. Check state Medicaid bulletins.
Commercial Payers
- Frequently audit psychological testing claims due to high costs.
- Require detailed documentation and may impose stricter pre-authorization rules.
- Some carriers may require network participation for reimbursement.
Real-World Example
A neuropsychologist at a private practice conducted 4 hours of testing for a child with suspected ADHD. They billed:
- 1 unit of 96130 (initial evaluation)
- 3 units of 96131 (additional evaluation time)
- 4 units of 96136/96137 (test administration)
Due to detailed documentation and prior authorization, the entire claim was approved within 21 days. The psychologist noted the specific tools used, and time logs, and explained how the results would guide medication and therapy recommendations.
Reference
According to the APA Billing and Coding Guide, accurate use of CPT codes and proper documentation are essential for ensuring insurance reimbursement.
Why It Matters
Billing psychological testing incorrectly can lead to lost revenue, audits, or even recoupment. These services are valuable but come with stringent billing rules. Staying informed ensures providers are compensated fairly for their expertise. Clinics that undercode may lose money while overbilling can trigger audits. Therapists often face unique billing challenges. This overview breaks down key strategies for medical billing for therapists in private practice.
