"CPT" in the medical billing context is unfortunately ambiguous — the procedure-coding CPT (Current Procedural Terminology, the AMA's coding system) and the cognitive-testing CPT (Continuous Performance Test, an attention assessment) share the same acronym. The procedure codes used to bill for objective ADHD testing belong to the Psychological and Neuropsychological Test Administration family, primarily 96136–96139 in the AMA CPT codebook.

This article focuses on US coding. UK NHS commissioners use different frameworks; private pay outside the US varies by jurisdiction.

The relevant codes

96136 / 96137 — Psychological or neuropsychological test administration by clinician

Used when the licensed clinician (psychologist, neuropsychologist, qualified physician) administers and scores tests in person, time-based:

  • 96136 — first 30 minutes
  • 96137 — each additional 30 minutes

96138 / 96139 — Test administration by technician

Used when a qualified technician administers tests under clinician supervision, time-based:

  • 96138 — first 30 minutes
  • 96139 — each additional 30 minutes

96130 / 96131 — Psychological testing evaluation services

Used for the clinician's professional time on integration, scoring, interpretation, and report generation — separate from administration time:

  • 96130 — first 60 minutes (psychological testing evaluation)
  • 96131 — each additional 60 minutes

Neuropsychological versions: 96132 (first 60 min) and 96133 (additional 60 min).

How CPT testing typically gets billed

For a CPT-only administration:

  • Most CPT administrations take 15–25 minutes including setup, instructions, the test itself, and patient debrief — usually one unit of 96136 or 96138.
  • If administered in the same session as longer assessment work (rating scales, structured interview), administration time is summed.

Plus typically one unit of 96130 (or 96132 for neuropsych) for the clinician's review, integration, and report time.

Documentation requirements

Most payers expect the chart note to include:

  • Specific test administered (by name)
  • Total face-to-face administration time
  • Identity of the administrator (clinician vs. technician under supervision)
  • Clinical question being addressed (e.g., "objective measurement of attention to inform diagnostic differential and treatment decision")
  • Integration of results with other clinical data in the assessment note
  • Score interpretation and clinical impression

Common payer nuances

  • Medicare generally covers psychological/neuropsychological test administration when medically necessary; the LCDs (Local Coverage Determinations) define documentation specifics by region.
  • Commercial payers often cover under behavioral health benefits but may require prior authorization or have specific medical-necessity language. Some require documented failure of subjective assessment to justify objective testing.
  • Medicaid coverage varies dramatically by state.
  • Telehealth-administered CPT billing is evolving. Most payers accept the standard administration codes when the test is administered remotely under appropriate supervision; some have specific telehealth modifiers (e.g., GT, 95) required.

What doesn't get paid (separately)

  • Patient time spent reviewing results in a follow-up visit — that's part of normal E/M coding for the visit.
  • Per-test platform fees from the CPT vendor (these are operational costs, billed separately as supply/equipment if at all).
  • Administrative scheduling, insurance verification, etc.

Practical workflow

  1. Document the medical necessity in the chart prior to ordering the test.
  2. Capture face-to-face administration time precisely — billing is time-based.
  3. Use the technician codes (96138/96139) when an MA, RN, or trained technician administers; use the clinician codes (96136/96137) when you administer personally. Document accordingly.
  4. Bill the integration/interpretation code (96130) on the date you complete the report and integrate findings into your clinical impression.
  5. Verify payer-specific requirements before ordering — particularly prior authorization status.

Self-pay framing

For practices billing patients directly, transparent pricing for objective testing typically ranges $80–$250 per administration depending on practice setting and what's bundled. Some platforms (notably AxonCPT) publish their per-test platform pricing publicly, which simplifies pass-through pricing.
