OCF-18 Treatment Plans: How to Get Your Rehabilitation Benefits Approved in Ontario

The OCF-18: Your Gateway to Rehabilitation Funding

Under Ontario’s SABS, the primary mechanism for accessing medical and rehabilitation benefits is the Treatment and Assessment Plan (OCF-18). Your healthcare provider submits an OCF-18 to your insurer describing the proposed treatment, its duration, frequency, and estimated cost. The insurer must then approve or deny within a prescribed timeframe.

The Approval Timeline and Deemed Approval

For most treatment plans, the insurer has 10 business days from receipt to respond. Emergency treatment — where delay would jeopardize health or recovery — must receive a response within three business days. Where the insurer fails to respond within the applicable window without seeking an extension, the treatment plan is deemed approved under the SABS. Deemed approval is a powerful tool in cases where insurers are stalling.

Common Grounds for OCF-18 Denial

Insurers deny OCF-18s on various grounds: the treatment is not reasonable and necessary for injuries sustained; the claimant is in the MIG and the proposed treatment exceeds the $3,500 cap; the proposed provider is not authorized under the SABS; or cost exceeds the applicable fee schedule. Each ground is disputable at FSRA mediation and arbitration.

Section 38 Notices

Insurers must provide section 38 notices when they refuse or reduce proposed treatments. A valid section 38 notice starts the limitation period running on the disputed benefit. Understanding when notice was received and what it addresses is critical to timely dispute filing — another reason why legal involvement from the outset of a significant claim is important.
