The billing and coding information in this article is dependent on the coverage indications, limitations and/or medical necessity described in the associated LCD L34646 Psychological and Neuropsychological Testing.
Psychological and Neuropsychological Testing are diagnostic procedures that must be used as an important tool in making specific diagnoses or prognoses to aid in treatment planning and to address questions regarding treatment goals, efficacy, and patient disposition. Diagnostic procedures that have no impact on a patient’s plan of care or have no effect on treatment are not medically necessary. The CPT Codes discussed in this Billing and Coding Article are used to report the services provided during testing of the cognitive function of the central nervous system. The testing of cognitive processes, visual motor responses and abstractive abilities is accomplished by the combination of several types of testing procedures.
Coding Guidelines
References to providers throughout this policy include non-physicians, such as clinical psychologists, independent psychologist, nurse practitioners, clinical nurse specialists and physician assistants when the services performed are within the scope of their clinical practice/education, licensed and authorized under the state law.
A minimum of 31 minutes must be provided to report any per hour code.
Psychological or neuropsychological testing includes selection, administration and scoring of the tests, directly by the psychologist, neuropsychologist, physician or other qualified health care professional, by a technician under the clinician's direct supervision, by computerized test administration, or via some combination of these three approaches.
Typically, testing requires 4-8 hours to perform, including administration and scoring. If the testing is performed over several days, the time for all testing should be combined and reported on the last day of service.
Psychological and Neuropsychological testing is medically necessary for multiple reasons. The medical record must document the reason the tests are being performed. The LCD does not define coverage for either the medical or psychiatric diagnosis that may require the services.
Psychological and neuropsychological testing is not covered for Alzheimer’s diseases once a diagnosis has been made.
