A referral is a recommendation or formal authorization from your primary care physician (PCP) to see a specialist or receive a specific service. Whether you need a referral depends entirely on your plan type.
Referral requirements by plan type:
Even on plans that don’t require referrals, some insurers may require prior authorization for specific specialist services, imaging, or procedures. A referral and prior authorization are not the same thing — referrals come from your doctor, prior auth comes from your insurer.
If you’re on an HMO and your PCP declines to issue a referral for a service you believe is medically necessary, you have the right to appeal that decision.
Contact your PCP to request the referral and explain why you believe specialist care is necessary. If your PCP still won’t issue one, you can file an appeal with your insurer or request a second opinion from another PCP in the network. For urgent situations, some plans have expedited referral processes.
No. A referral from your PCP is a recommendation to see a specialist. Prior authorization is a separate approval from your insurer before a specific service or procedure is performed. Some services require both — a referral to get to the specialist, and prior auth from the insurer before they’ll pay for the procedure the specialist recommends.
