SHARON FUNG, MS, APN-CNS, CRRN appears in the CMS NPPES registry as a Rehabilitation Registered Nurse provider holding MS, APN-CNS, CRRN credentials at 1901 W HARRISON ST, CHICAGO, IL, 60612, with a listed phone of (312) 864-3680. NPI 1023138815 was issued on 03/29/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what FUNG 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 462 prescription claims written by this provider, covering 95 Medicare beneficiaries and totaling roughly $268K in drug spend, split 58% brand-name and 42% 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 84.5729/100 for the 2023 performance year (Quality 60.2504, Cost 67.0015), compared with the national average of 83.1.

Rehabilitation Registered Nurse is a narrow specialty nationwide, with 391 enrolled providers across 48 states and an average of 988 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.
