Summary & Overview
CPT 96139: Technician Test Administration and Scoring, Additional 30 Min
CPT 96139 designates technician-performed psychological or neuropsychological test administration and scoring for two or more tests, billed for each additional 30-minute increment. This code is used when technicians, under appropriate supervision, complete portions of multi-test batteries and requires separate reporting in addition to the primary procedure. Nationally, the code matters for workflows that distribute test administration tasks across care teams, affect clinic scheduling, and influence billing practices for multi-instrument cognitive and behavioral assessments. Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise explanation of the code’s clinical role and billing context, comparisons to related test-administration codes, and guidance on common procedural uses and reporting conventions. The publication addresses how the code fits into broader neuropsychological and psychological testing services, typical sites of service, and common clinical diagnoses for which multi-test batteries are used. Where input fields were incomplete, the publication notes missing metadata. The content is intended to inform billing staff, clinicians, and policy stakeholders about code purpose, typical application, and associated administrative considerations without providing clinical recommendations.
CPT Code Overview
CPT 96139 covers psychological or neuropsychological test administration and scoring performed by a technician, for two or more tests using any method, billed as each additional 30 minutes. The service type is Psychological/Neuropsychological Testing – Test Administration and Scoring, by technician. Typical site of service is office or other outpatient setting (POS 11).
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient is referred to an outpatient neuropsychology clinic for cognitive evaluation after a traumatic brain injury with new memory and attention problems. In the office setting, a technician administers and scores multiple standardized psychological and neuropsychological tests over sequential 30-minute intervals under the supervision of a licensed psychologist or neuropsychologist. Test administration by the technician follows a plan established by the supervising clinician; results are scored, documented, and forwarded to the supervising clinician for interpretation and reporting. Typical workflow includes check-in, technician-led test sessions (documenting start and stop times for each 30-minute unit), scoring, and transfer of scored materials to the supervising provider for clinical integration and final report generation.
Coding Specifications
-
59— Distinct Procedural Service: Use when the technician-administered testing represented by96139is a distinct service from other procedures performed on the same day (for example, a separate testing session distinct from brief clinic visits). Documentation must support a separate and distinct service. -
76— Repeat Procedure by Same Physician: Use when the same service represented by96139is repeated by the same group or supervising clinician for the same patient on the same day and billing requires indicating a repeated service. Documentation must support the repeat session.

Related Diagnoses
-
F07.0— Personality change due to known physiological conditionThis diagnosis is relevant when neuropsychological testing is used to evaluate changes in personality and behavior after a neurologic illness or injury; technician-administered tests provide objective measures for the supervising clinician.
-
F09— Unspecified mental disorder due to known physiological conditionThis code applies when a specific mental disorder related to a physiological condition is not specified; testing helps characterize cognitive or behavioral deficits for diagnostic clarification and treatment planning.
-
R41.3— Other amnesiaMemory impairment is commonly assessed with neuropsychological test batteries; technician-administered test sessions contribute timed administration and scoring for memory instruments.
-
R41.840— Attention and concentration deficitAttention deficits are evaluated with standardized tests that can be administered and scored by technicians, providing data used by the supervising clinician for interpretation.
-
R41.841— Cognitive communication deficitCommunication and higher-order cognitive-linguistic problems are evaluated using structured tests and subtests; technician administration and scoring yield objective results for the clinical report.

| CPT Code | Description | Relationship to 96139 |
|---|---|---|
96136 | Psychological or neuropsychological test administration and scoring by physician or other qualified health care professional, two or more tests, any method; first 30 minutes | Represents the first 30-minute unit when a qualified provider (not a technician) administers and scores testing; an alternative when qualified personnel perform the testing rather than a technician. |
96137 | Psychological or neuropsychological test administration and scoring by physician or other qualified health care professional, two or more tests, any method; each additional 30 minutes | Represents additional 30-minute units billed by a qualified provider following the initial 96136; an alternative/add-on when provider (not technician) time extends beyond the first unit. |
96138 | Psychological or neuropsychological test administration and scoring by technician, two or more tests, any method; first 30 minutes | Represents the first 30-minute unit for technician-administered testing; 96139 is billed for each additional 30-minute unit following 96138. |
96146 | Automated testing and results for psychological/neuropsychological testing | Represents automated scoring or computer-administered testing results; may be used in workflows that combine technician administration (96138/96139) with automated test result processing. |
Common combinations: 96138 (first 30 minutes, technician) followed by one or more 96139 units (each additional 30 minutes). Alternatively, when a qualified clinician administers testing, 96136 is used for the first 30 minutes and 96137 for additional 30-minute units.
