COLLINS LIU, MD appears in the CMS NPPES registry as a Diagnostic Neuroimaging (Psychiatry & Neurology) Physician provider holding MD credentials at 11120 E OCEAN AIR DR STE 101-88, SAN DIEGO, CA, 92130, with a listed phone of (619) 630-8676. NPI 1851547459 was issued on 08/14/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LIU 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 800 prescription claims written by this provider, covering 98 Medicare beneficiaries and totaling roughly $94K in drug spend, split 5% brand-name and 95% generic by claim count. 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.

Diagnostic Neuroimaging (Psychiatry & Neurology) Physician is a narrow specialty nationwide, with 30 enrolled providers across 16 states and an average of 1,149 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.
