A written order from your primary care doctor for you to see a specialist or get certain medical services. In many Health Maintenance Organizations (HMOs), you need to get a referral before you can get medical care from anyone except your primary care doctor. If you don’t get a referral first, the plan may not pay for the services. Referrals are not required for Health First Colorado (Colorado’s Medicaid Program) members enrolled in the Accountable Care Collaborative (ACC).

Check with your health insurance plan to see what requires a referral.
