ANDREA TIAN, MD appears in the CMS NPPES registry as a Orthopaedic Hand Surgery Physician provider holding MD credentials at 18200 KATY FWY, HOUSTON, TX, 77094, with a listed phone of (832) 227-1000. NPI 1861986820 was issued on 06/21/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what TIAN 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 45 prescription claims written by this provider, covering 29 Medicare beneficiaries and totaling roughly $554 in drug spend, with an opioid prescribing rate of 60.0%. 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.

Orthopaedic Hand Surgery Physician is a narrow specialty nationwide, with 1,962 enrolled providers across 52 states and an average of 180 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.
