If bipartisan legislation proposed by Rep. Paul Tonko (D-NY) and Rep. David McKinley (R-WV) is approved, fewer physicians would have to wait for permission to prescribe addiction treatment drugs. Under the bill, the need for “prior authorization” would be eliminated in state Medicaid programs for addiction treatment medicines such as buprenorphine. As of 2018, 40 states required some level of prior authorization for buprenorphine, while 31 states required prior authorization for a common treatment that combines buprenorphine and naloxone. Tonko and McKinley’s bill would apply only to Medicaid and not to commercial insurance providers.
