"Under current regulations, physicians that are certified to prescribe buprenorphine for MAT are allowed to prescribe up to 30 patients initially and then after one year can request authorization to prescribe up to a maximum of 100 patients. This cap on prescribing limits the ability of some physicians to prescribe to patients with opioid use disorder.  If adopted, the proposed rulemaking would allow for a qualified and currently waivered physician to prescribe buprenorphine for up to 200 patients.  Existing evidence shows that this lifesaving, evidence-based treatment is under-utilized. This proposed expansion is especially important to people who are seeking help for an untreated opioid use disorder.  In many cases there are long waiting lists of patients for prescribers who have reached the 100 patient limit.  Easing additional barriers to treatment, such as this cap, is a major step HHS is taking to help reduce prescription opioid and heroin related overdose, death, and dependence.  The proposed rule is designed to strike an appropriate balance between expanding access to this important treatment, encouraging use of evidence-based MAT, and minimizing the risk of drug diversion.   

HHS welcomes public comment on this proposed rule, which will be open for comment for 60 days starting Wednesday, March 30, 2016."
