Which letter represents a full practitioner with buprenorphine privileges?

The letter that represents a full practitioner with buprenorphine privileges is C, which stands for the X waiver or X number. This designation is issued to qualified healthcare providers who have undergone specialized training and have been granted permission to prescribe buprenorphine for the treatment of opioid use disorder.

In order to qualify for the X waiver, practitioners must complete an approved training course and apply for a Drug Enforcement Administration (DEA) registration that includes the X designation. This allows them to prescribe this specific medication, which is a critical part of the substance use disorder treatment landscape. The inclusion of the X in the DEA number is an important marker indicating that the provider is authorized and has met the regulatory requirements set forth for managing patients with opioid dependency.

Other letters do not indicate a practitioner equipped with these specific privileges related to buprenorphine and its use for treating opioid use disorder, which is why they are not the correct choice. The understanding of this designation is crucial for ensuring compliance with federal regulations in the treatment of opioid use disorders.
