Billing for mental health services involves the process of submitting and managing insurance claims for treatments provided by mental health professionals such as psychologists, psychiatrists, therapists, and counselors. It includes documenting therapy sessions, assigning the correct CPT and ICD-10 codes, verifying patient insurance coverage, obtaining prior authorizations, and submitting claims to insurance companies for reimbursement. Because mental health care often includes various session types—individual therapy, family counseling, medication management, and telehealth—accurate documentation and coding are essential to avoid claim denials.
