BYRON ERSTINE, D.O. appears in the CMS NPPES registry as a Otolaryngology/Facial Plastic Surgery Physician provider holding D.O. credentials at 2907 HILLRISE DR, LAS CRUCES, NM, 88011, with a listed phone of (575) 449-8949. NPI 1487847174 was issued on 08/25/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ERSTINE 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 395 prescription claims written by this provider, covering 175 Medicare beneficiaries and totaling roughly $17K in drug spend. 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.

Otolaryngology/Facial Plastic Surgery Physician is a narrow specialty nationwide, with 744 enrolled providers across 53 states and an average of 561 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
