MACY SUN, FNP-BC appears in the CMS NPPES registry as a Infusion Therapy Registered Nurse provider holding FNP-BC credentials at 6955 FOOTHILL BLVD STE 67A, OAKLAND, CA, 94605, with a listed phone of (510) 969-5067. NPI 1790313047 was issued on 03/31/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SUN 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 222 prescription claims written by this provider, covering 96 Medicare beneficiaries and totaling roughly $324K in drug spend, split 18% brand-name and 82% generic by claim count, with an opioid prescribing rate of 10.8%. 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.

Infusion Therapy Registered Nurse is a narrow specialty nationwide, with 689 enrolled providers across 50 states and an average of 784 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.
