What is the difference between a referral and a prescription?
A referral is the initial authorization you receive from your primary care physician. It is usually required by an HMO insurance plan, but may not be required by other types of insurance plans.
A prescription states what the treatment is and how often your are to receive the treatment. For example, a prescription for a specific medication will tell you the dosage - or strength - of the medicine and it will tell you how often you are to take the medication. A prescription for therapy may simply state "evaluate and treat," or it may be much more specific as to the what condition is to be evaluated and what sort of treatment is to be given.
