What does it signify if a prescriber has a DEA number that starts with an X?

A DEA number that starts with an X indicates that the prescriber has been specially trained and certified to prescribe buprenorphine for the outpatient treatment of opioid use disorder. This certification allows them to treat patients suffering from opioid addiction with buprenorphine, a medication that helps manage withdrawal symptoms and cravings.

This specific designation is important due to the legal framework established by the Drug Addiction Treatment Act (DATA) of 2000, which aims to ensure that only qualified practitioners can prescribe treatments for opioid addiction. The presence of an X in the DEA number signifies that the provider has met the additional requirements set forth by the Substance Abuse and Mental Health Services Administration (SAMHSA) and other regulatory authorities.

Thus, the correct answer accurately reflects the unique authorization associated with a DEA number starting with X, differentiating these prescribers from others who may have broader or different prescribing privileges.
