LAN SU, DMD PHD appears in the CMS NPPES registry as a Oral and Maxillofacial Pathology Dentistry provider holding DMD PHD credentials at 31332 VIA COLINAS STE 109, WESTLAKE VILLAGE, CA, 91362, with a listed phone of (818) 865-1039. NPI 1184869463 was issued on 12/15/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SU 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 1,014 prescription claims written by this provider, covering 156 Medicare beneficiaries and totaling roughly $97K 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.

Oral and Maxillofacial Pathology Dentistry is a narrow specialty nationwide, with 690 enrolled providers across 48 states and an average of 303 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.
