What is the difference between an OHIP ADHD assessment and a private psychoeducational assessment in Ontario?

An OHIP-path ADHD assessment in Ontario is a medically necessary physician or nurse practitioner evaluation that can be insured when the clinician provides insured services; a private psychoeducational assessment is a psychologist-led battery that OHIP does not list as an insured physician service. The public path is usually a family doctor, NP, walk-in physician, or psychiatrist taking a history, using screening tools, considering other conditions, and deciding about diagnosis and treatment. It may or may not produce a long written report. The private psychoeducational path typically includes standardized cognitive and academic testing, a detailed report, and a fee paid by you or a private insurer. Those two products answer different questions. Rules, coverage and referral pathways vary by province and can change; confirm the current position with the relevant institution or provincial program.
