Aetna Neuropsychological and Psychological Testing coverage criteria

Aetna CPB 0158 covers neuropsychological testing (NPT) and psychological testing (PT) as medically necessary only when they pass a five-part validity/appropriateness gate (reasonable time, validated and non-redundant techniques, age/population-appropriate current instruments with sound psychometrics) AND are tied to a covered clinical purpose — e.g., assessing neurocognitive ability after brain injury/stroke/neurosurgery or in epilepsy/hydrocephalus/AIDS, planning rehabilitation, differentiating psychogenic vs neurogenic syndromes, monitoring cognitive decline, clarifying complex psychiatric diagnoses or treatment-refractory cases, distinguishing ADHD from learning/communication disorders, and diagnosing pervasive developmental disorders. Testing for educational, employment, disability, legal/court, or toxic-exposure (worker's comp) purposes is excluded, several uses are deemed not medically necessary (e.g., chronic fatigue syndrome, migraine, pre-surgical clearance, neurodiversity, uncomplicated ADHD, or while actively using substances), and computerized assessment devices like Cognitrax are experimental for screening; the bulletin is silent on precertification.

Path
Aetna CPB 0158 covers neuropsychological testing (NPT) and psychological testing (PT) as medically necessary only when they pass a five-part validity/appropriateness gate (reasonable time, validated and non-redundant techniques, age/population-appropriate current instruments with sound psychometrics) AND are tied to a covered clinical purpose — e.g., assessing neurocognitive ability after brain injury/stroke/neurosurgery or in epilepsy/hydrocephalus/AIDS, planning rehabilitation, differentiating psychogenic vs neurogenic syndromes, monitoring cognitive decline, clarifying complex psychiatric diagnoses or treatment-refractory cases, distinguishing ADHD from learning/communication disorders, and diagnosing pervasive developmental disorders.

Coverage criteria include: General medical-necessity gate for Neuropsychological Testing (NPT) — covered ONLY when ALL of the following are met: (1) number of hours/units does not exceed the reasonable time necessary to address the clinical questions; (2) testing techniques are validated for the proposed diagnostic question or treatment plan; (3) testing techniques do not represent redundant measurements of the same cognitive, behavioral, or emotional domain; (4) testing techniques are validated for the member's age and population and use the most updated version of the instrument; (5) instruments have empirically substantiated reliability, validity, standardized administration, and clinically relevant normative data; NPT medically necessary (when general criteria met) for: assessment of neurocognitive abilities following traumatic brain injury, stroke, or neurosurgery, or relating to a medical diagnosis such as epilepsy, hydrocephalus, or AIDS; NPT medically necessary (when general criteria met) for: assessment of neurocognitive functions to assist in the development of rehabilitation and/or management strategies for persons with diagnosed neurological disorders; NPT medically necessary (when general criteria met) for: differential diagnosis between psychogenic and neurogenic syndromes; NPT medically necessary (when general criteria met) for: monitoring of the progression of cognitive impairment secondary to neurological disorders; NPT or Psychological Testing (PT) to enhance psychiatric or psychotherapeutic treatment outcomes after a detailed diagnostic evaluation — medically necessary when needed AND all general medical-necessity criteria are met, where testing is needed for ONE of: (a) to aid differential diagnosis of behavioral/psychiatric conditions when the member's history and symptomatology are not readily attributable to a particular diagnosis AND the questions cannot be resolved by psychiatric/diagnostic interview, observation in therapy, or assessment for level of care; OR (b) to develop treatment recommendations after the member has been tried on various medications and/or psychotherapy, has not progressed in treatment, and continues to be symptomatic; NPT medically necessary to distinguish attention deficit/hyperactivity disorder (ADHD) from learning disabilities or language/communication disorders when such distinction remains unclear after history and examination; NPT may be considered medically necessary for neurologically complicated cases of ADHD (e.g., post head trauma, seizures); Referral to an outpatient mental health provider or outpatient substance use disorder treatment may be considered medically necessary for evaluation and comprehensive bio-psychosocial treatment for ADHD in collaboration with primary care physicians; NPT or PT involving standardized parent interviews and direct, structured behavioral observation is medically necessary (when general criteria met) for the diagnosis of pervasive developmental disorders; PT may be medically necessary to differentiate chronic fatigue syndrome from psychiatric diagnoses when the criteria for PT are met. Applies to 12 codes: 96116, 96121, 96125, 96130, 96131, 96132, 96133, 96136, 96137, 96138, 96139, 96146.

Trap
Policy exclusions and limitations: Experimental, investigational, or unproven: Computerized neuropsychological assessment devices (e.g., Cognitrax) for screening asymptomatic / healthy individuals, and for other indications (e.g., screening and monitoring multiple sclerosis-related cognitive impairment; not an all-inclusive list); Not medically necessary: NPT for the diagnosis and management of persons with chronic fatigue syndrome (Note: PT may be medically necessary to differentiate chronic fatigue syndrome from psychiatric diagnoses when criteria for PT are met); Not medically necessary: NPT for the evaluation of migraineurs; Not medically necessary: NPT or PT if the member is actively abusing substances, is having acute withdrawal symptoms, or has recently entered recovery, because test results may be invalid; Not medically necessary: Diagnostic assessment for neurodiversity, because of a lack of evidence regarding the clinical value of neurodiversity tests; Not medically necessary: NPT and PT generally for pre-surgical clearance; Not medically necessary: NPT or PT rarely considered medically necessary for uncomplicated cases of attention deficit disorder with/without hyperactivity (ADHD); Not covered (policy exclusion): NPT or PT for educational reasons — not considered treatment of disease; this testing is usually provided by school systems under applicable state and federal rules; Not covered (policy exclusion): NPT or PT for employment, disability qualification, or legal/court-related purposes — not considered treatment of disease; Not covered under Aetna medical or mental health benefits (policy exclusion): NPT used in evaluating the impact of chronic solvent or heavy metal exposure (e.g., in the occupational or environmental medicine realm) — may instead be covered by the worker's compensation carrier.
