Opioids - As enacted, authorizes an insurer, for purposes of group insurance plans offered to state employees, to adopt or amend a state preferred drug list (PDL); requires the insurer to ensure that a non-opioid drug approved by the U.S. food and drug administration for the treatment or management of pain is not disadvantaged or discouraged with respect to coverage relative to an opioid or narcotic drug for the treatment or management of pain on the PDL. - Amends TCA Title 8; Title 53; Title 56; Title 63; Title 68 and Title 71.

HB 37 requires insurers offering health plans to Tennessee state employees to treat FDA-approved non-opioid pain medications equally with opioids on their preferred drug lists (PDL). It prohibits insurers from discouraging coverage for non-opioid options used for pain management, though it allows insurers to prefer one opioid over another or one non-opioid over another. This applies specifically to state employee group insurance plans covered under Tennessee Code Annotated sections 56-7-3801 to 56-7-3803. The law, effective January 1, 2026, aims to expand access to non-opioid pain treatments without mandating their preference.
