About Psychologist Providers

A psychologist is a licensed mental health professional who studies human behavior, cognitive processes, and emotional functioning. They diagnose and treat psychological disorders, provide therapy, and conduct behavioral assessments. Psychologists hold a doctoral degree (PhD, PsyD, or EdD) in psychology, complete supervised clinical hours, and pass state licensing exams. While they generally do not prescribe medications, they utilize evidence-based psychotherapies, counseling, and diagnostic testing to help patients overcome emotional distress and manage mental health conditions.

Finding a psychologist's NPI number is crucial for billing insurance companies and obtaining coverage for therapy and mental health evaluations. Billers use the psychologist's NPI on medical claim forms to ensure the provider is recognized by insurance carriers. The NPPES registry verifies the psychologist's licensing status, specialty taxonomy, and practice location. Checking the NPI registry helps ensure that patients are working with a registered professional, preventing claims rejections and securing eligible mental health coverage.
