MICHAEL BRENEGAN, D.D.S. appears in the CMS NPPES registry as a Periodontics provider holding D.D.S. credentials at 1001 DARRINGTON DR STE 110, CARY, NC, 27513, with a listed phone of (919) 469-9986. NPI 1154550796 was issued on 07/03/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BRENEGAN most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 192 prescription claims written by this provider, covering 126 Medicare beneficiaries and totaling roughly $937 in drug spend, with an opioid prescribing rate of 9.9%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Periodontics is a mid-sized specialty nationwide, with 6,061 enrolled providers across 53 states and an average of 264 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
