QUYNHAN CHAU appears in the CMS NPPES registry as a Geriatric Medicine (Internal Medicine) Physician provider at 1287 N SEMORAN BLVD STE 200, ORLANDO, FL, 32807, with a listed phone of (407) 273-9410. NPI 1942628235 was issued on 04/03/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHAU 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 7,032 prescription claims written by this provider, covering 607 Medicare beneficiaries and totaling roughly $650K in drug spend, split 18% brand-name and 82% generic by claim count, with an opioid prescribing rate of 3.5%. 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.

Geriatric Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 4,161 enrolled providers across 52 states and an average of 4,450 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.
