In clinical settings, structured and standardized screening allows healthcare providers to identify symptoms before they escalate, improving outcomes while ensuring compliance with evolving medical standards. This guideline presents a concise, evidence-informed approach to behavioral health evaluation across diverse populations. From tool selection to interpretation and referral protocols, it equips practitioners with the clinical clarity needed to navigate complex patient needs. Designed for physicians integrating mental health into routine care, this document aligns screening practices with diagnostic accuracy, patient safety, and systemic efficiency.
Assessment of Aphasia and Cognitive Performance Testing
Assessment of aphasia and cognitive performance plays a critical role in identifying deficits resulting from neurological events such as stroke, traumatic brain injury (TBI), or progressive conditions like dementia. These evaluations guide treatment planning, support functional recovery, and ensure accurate documentation for medical necessity and reimbursement.
CPT Codes Overview
96105 – Assessment of Aphasia
- Definition: This code represents the assessment of expressive and receptive speech and language function, including comprehension, speech production, reading, spelling, and writing.
- Administration: Typically performed using standardized instruments such as the Boston Diagnostic Aphasia Examination (BDAE).
- Time-Based Billing: Billed per hour, inclusive of face-to-face administration, interpretation, and report preparation.
- Documentation Requirements: The report must include:
- Observed deficits in expressive/receptive language
- Interpretation of findings
- Impact on daily living and functional communication
96125 – Standardized Cognitive Performance Testing
- Definition: This code encompasses formal testing of cognitive domains, including memory, attention, executive function, problem-solving, and language processing.
- Instruments Used: Common tools include the Ross Information Processing Assessment (RIPA), California Verbal Learning Test (CVLT), and Neuropsychological Assessment Battery (NAB).
- Qualified Providers: Can be administered by skilled professionals (e.g., neuropsychologists, speech-language pathologists, clinical psychologists), as per AMA scope-of-practice definitions.
- Billing Criteria:
- Time-based (per hour)
- Includes both test administration and professional time for interpretation and report writing
Clinical and Documentation Standards (CMS-Aligned)
Per CMS guidelines and Medicare policies, both CPT 96105 and 96125 must meet the following conditions:
- Medically Necessary Services: These assessments are reimbursable when they are essential for diagnosis, treatment planning, or monitoring a patient’s condition. Justification must be documented.
- Qualified Professional Requirement: Only clinicians with recognized credentials and training appropriate to the test being administered are permitted to bill these codes. Each service must be within its defined scope of practice.
- Detailed Reporting: A comprehensive report is mandatory and must include:
- Reason for referral
- Standardized tools used
- Objective findings and interpretation
- Functional impact on patients’ activities of daily living (ADLs)
- Clinical recommendations
- ICD-10 Coding Considerations: While coverage is not diagnosis-specific, appropriate ICD-10 codes (e.g., I69.321 – Aphasia following cerebral infarction, F07.81 – Postconcussional syndrome, G31.84 – Mild cognitive impairment) must be selected based on the patient’s documented condition and medical necessity.
- Time Tracking: Providers must record the exact amount of time spent in testing, interpretation, and documentation. Only time meeting CMS definitions of face-to-face or professional interpretive work may be billed.
Important Notes
- According to the CPT 2025 Manual, all testing must follow standardized administration and scoring protocols to be considered valid and billable.
- Providers should avoid billing both codes (96105 and 96125) on the same day unless clinically justified and separately documented.
- CMS explicitly requires that all services be reported by local coverage determinations (LCDs) and national coverage determinations (NCDs) where applicable.
Developmental and Behavioral Screening and Testing
Developmental and behavioral screenings are vital components of pediatric healthcare, serving to identify early signs of developmental delays, language deficits, and behavioral concerns. These screenings enable providers to intervene promptly, improving long-term outcomes for children with conditions such as autism spectrum disorder (ASD), speech delays, ADHD, or cognitive impairments.
The CPT codes used in these evaluations reflect the type, complexity, and duration of the services rendered. Each code is linked to a specific set of standardized instruments and must be supported by appropriate clinical documentation and medical necessity.
CPT Codes for Developmental and Behavioral Screening/Testing
96110 – Developmental Screening, Per Standardized Instrument
- Use Case: Brief standardized screening tools, such as the Ages and Stages Questionnaire (ASQ) and the Modified Checklist for Autism in Toddlers (M-CHAT).
- Performed By: Auxiliary staff (e.g., nurses, MAs) under the supervision of a qualified healthcare professional.
- Coverage: Medicare covers 96110 when medically necessary and documented in accordance with CMS guidelines.
- Documentation Must Include:
- The name of the instrument used
- Scoring methodology
- Interpretation of results
- Impact on care planning
96112 – Developmental Testing, First Hour
- Use Case: In-depth evaluation of motor, language, social, adaptive, and/or cognitive functioning using standardized instruments.
- Performed by: Qualified professionals such as psychologists, pediatricians, or speech-language pathologists.
- Time-Based: Billed for the first hour of testing, including interpretation and report preparation.
- Medical Necessity Requirement: Documented reason for referral and clinical justification in the medical record.
96113 – Developmental Testing, Each Additional 30 Minutes
- Add-On Code: Used in conjunction with 96112 for each additional 30 minutes of qualified face-to-face and interpretive time.
- Billing Rule: A unit of time is considered met when the midpoint is passed (i.e., ≥16 minutes for 96113).
96127 – Brief Emotional/Behavioral Assessment
- Use Case: Screening for emotional and behavioral conditions (e.g., depression, ADHD) using tools like PHQ-2, PHQ-9, or Vanderbilt Assessment Scales.
- Performed by: Auxiliary personnel with proper training, under clinical supervision.
- Documentation Must Include:
- Instrument name
- Scoring and interpretation
- Connection to care decisions
Clinical and Coding Considerations
- Screening vs. Testing:
- Screening (96110, 96127): Brief tools used to flag potential issues.
- Testing (96112, 96113): Detailed diagnostic procedures used for confirmed or suspected developmental/behavioral conditions.
- Medical Necessity and Documentation:
- The record must explain the reason for the test.
- It must be clinically justified, not simply routine.
- Use ICD-10 codes that reflect suspected or known conditions (e.g., R62.50 – Unspecified lack of expected normal physiological development in childhood, F84.0 – Autistic disorder, F90.9 – ADHD, unspecified type).
- Qualified Providers:
- Only providers with recognized credentials and training should perform and interpret developmental and behavioral tests.
- This includes psychologists, developmental-behavioral pediatricians, and other CMS-approved professionals.
Clarification on HCPCS Codes: G0513 and G0514
Although sometimes confused with behavioral screening codes, G0513 and G0514 are not appropriate for developmental or behavioral testing. These codes are used for prolonged preventive services and are not billable for services covered under CPT 96110–96127.
Neurobehavioral Status Examination
The Neurobehavioral Status Examination is a comprehensive, face-to-face clinical assessment of a patient’s cognitive and behavioral functioning. It evaluates domains such as attention, memory, executive function, language, reasoning, visuospatial skills, and emotional regulation. This service is most often used in the assessment of individuals with brain injuries, psychiatric conditions, dementia, or other neurologically based cognitive impairments.
CPT Codes for Neurobehavioral Status Exams
96116 – Initial Hour
- Definition: Clinical assessment of cognition and behavior, including domains like acquired knowledge, attention, language, memory, planning, problem-solving, and visuospatial abilities.
- Time-Based: Billed per hour (≥31 minutes).
- Includes:
- Face-to-face evaluation
- Interpretation of test data
- Preparation of a detailed report
96121 – Each Additional Hour
- Add-On Code: Reported separately in addition to 96116.
- Time-Based: Used for each additional hour (≥16 minutes) of service.
- Documentation Must Include:
- Total time spent

- Are well-documented in the patient’s record to support reimbursement
- Reflect the complexity of the patient’s clinical presentation
Commonly Used Assessment Instruments
Although not individually billed, these tools often contribute to the exam:
- MMSE (Mini-Mental State Examination)
- MoCA (Montreal Cognitive Assessment)
- Neuropsychological Assessment Battery (NAB)
These tools help quantify performance across domains but must be interpreted in the context of clinical observation and patient history.
ICD-10 Coding Guidance
There are no fixed ICD-10 codes tied to 96116/96121; however, the codes billed should reflect:
- The clinical indication for testing
- A suspected or confirmed neurological or psychiatric disorder
Examples include:
- G31.84 – Mild cognitive impairment
- F02.80 – Dementia in other diseases classified elsewhere, without behavioral disturbance
- F07.89 – Other personality and behavioral disorders due to known physiological condition
Note: Coverage is not diagnosis-specific, but medical necessity must be well justified.
