Referral vs Authorization

A Referral is not the same as an Authorization. 

In general a referral is required when a PCP refers a patient to a specialist in-network provider for consultation, while an Authorization also known as Prior Authorization, is approval from the Insurance plan for the performance of certain specific medical procedures and services, based on medical necessity.

A typical scenario would be a PCP referring a patient to a in-network Nephrologist. A referral would be required without which the Insurance plan will not pay. If the Nephrologist performs only an evaluation, the referral alone would suffice, but if the Nephrologist chooses to administer a Procrit injection, than this procedure ( which is on the Prior authorization list of the Insurance plan ) would require a Prior authorization for the Insurance plan to make payment.

Referral :

• A referral is required when a PCP refers a patient to a specialist
• HMO Plans in general require a referral while PPO plans do not require a referral
• A referral is valid for a certain period and for a certain number of visits
• A referral is not required for Emergency services
• A referral is not required for Routine / Preventive services
• Without a referral the insurance plan will not pay

Prior Authorization :

• A Prior authorization is required when a provider plans on performing a procedure which is on the Prior authorization list of the Insurance plan
• A Prior authorization needs to be obtained from the Insurance plan before the performance of the medical procedure
• A Prior authorization is provided by the Insurance plan when they are satisfied as to the medical necessity of the procedure
• A Prior authorization is not required for Emergency services
• Without a Prior authorization the Insurance plan will not pay for procedures that are on its Prior authorization list
