HUYEN-CHAU DUNN, D.D.S. appears in the CMS NPPES registry as a Oral and Maxillofacial Surgery (Dentist) provider holding D.D.S. credentials at 5318 NC HIGHWAY 55 STE 106, DURHAM, NC, 27713, with a listed phone of (919) 806-2912. NPI 1013906486 was issued on 10/18/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DUNN 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 182 prescription claims written by this provider, covering 87 Medicare beneficiaries and totaling roughly $818 in drug spend, with an opioid prescribing rate of 41.2%. 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.

Oral and Maxillofacial Surgery (Dentist) is a mid-sized specialty nationwide, with 7,631 enrolled providers across 52 states and an average of 378 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.
