Okla. Stat. tit. 59, § 59-521.2: Billing and payment

A. Payment for services within the physician assistant's scope

of practice by a health insurance plan shall be made when ordered or

performed by the physician assistant, if the same service would have

been covered if ordered or performed by a physician. An in-network

physician assistant shall be authorized to bill for and receive

direct payment for the medically necessary services the physician

assistant delivers.

B. To ensure accountability and transparency for patients,

payers and the health care system, an in-network physician assistant

shall be identified as the rendering professional in the billing and

claims process when the physician assistant delivers medical or

surgical services to patients.

C. No insurance company or third-party payer shall impose a

practice, education, or collaboration requirement that is

inconsistent with or more restrictive than existing physician

assistant state laws or regulations.
