Ark. Code Ann. § 23-66-701

The General Assembly hereby finds that registry numbers issued to physicians by the Drug Enforcement Administration are protected numbers not intended for use by insurance companies and health maintenance organizations. Pharmacists are prohibited by law from selling or dispensing controlled substances without a physician's Drug Enforcement Administration registry number, and disclosure of the registry number to insurers is unwarranted and inappropriate. The intent of this subchapter is to prohibit insurance companies and health maintenance organizations from requiring physicians, pharmacists, or others to disclose a physician's Drug Enforcement Administration registry number.
