What is external review?
External review is an independent look at certain coverage denials by an OID-certified independent review organization (IRO) with no connection to your health plan.
Under the Uniform Health Carrier External Review Act (36 O.S. § 6475), external review addresses denials based on medical necessity, appropriateness, health care setting, level of care, effectiveness, or experimental/investigational treatment. The IRO decision is binding on the health carrier (§ 6475.11). There is no cost to you—the carrier pays IRO fees.

Who can use Oklahoma review?
OID external review under § 6475 generally applies when:
- You have OID-regulated commercial coverage (many HealthCare.gov and fully insured employer plans)
- The denial is an adverse determination or final adverse determination based on clinical review—not pure contractual exclusions, eligibility, or premium disputes
- You exhausted internal grievance—or qualify to bypass or proceed with mutual agreement
Usually does not apply to:
- Self-funded ERISA employer plans (federal external review may still apply)
- Medicare, Medicaid (SoonerCare), and other federal plans
- Services that are not covered benefits under your policy (even if you believe they are medically necessary)
OID randomly assigns a certified IRO after your request is eligible (OID — external review).
Deadlines & exhaustion
Four months (§ 6475.10)
File a written external review request with the Insurance Commissioner (OID) within four (4) months after receipt of an adverse determination or final adverse determination (§ 6475.10).
Exhaust internal grievance first
Complete the carrier's internal grievance unless you and the carrier agree to proceed directly to external review, or you qualify to bypass because delay would jeopardize life or health.
Additional information to the IRO
After OID assigns an IRO, you may submit additional written information within 5 business days of the assignment notice (§ 6475.8).

How long it takes
- Carrier preliminary eligibility review within 5 business days after OID forwards your request (§ 6475.8)
- Standard external review: IRO decision within 45 days after receipt of the request (§ 6475.8(I))
- Expedited external review: within 72 hours when delay would jeopardize life, health, or ability to regain maximum function, or for certain admission/continued-stay situations (§ 6475.9)
Is the decision binding?
For qualifying external reviews, the IRO decision is binding on the health carrier and on you except where other legal remedies apply (§ 6475.11). If the IRO reverses the denial, the carrier must immediately approve coverage.
You cannot file a second external review on the same final adverse determination.
