California Code, Business and Professions Code - BPC § 682

An individual authorized to prescribe emergency contraception who issues a prescription or order for emergency contraception drug therapy as a result of a patient contact by telephone or electronic means may not charge an administrative fee or fees totaling more than ten dollars ($10) for emergency contraception drug therapy services. This limitation is not intended to interfere with other contractually agreed-upon terms between an individual prescriber and a health care service plan, insurer, or disability insurer for payment directly to the prescriber by the plan or insurer.
