JOSEPH BIBER, M.D. appears in the CMS NPPES registry as a Cornea and External Diseases Specialist Physician provider holding M.D. credentials at 135 S SHARON AMITY RD, CHARLOTTE, NC, 28211, with a listed phone of (704) 365-0555. NPI 1457440620 was issued on 10/12/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BIBER 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 2,610 prescription claims written by this provider, covering 850 Medicare beneficiaries and totaling roughly $561K in drug spend, split 59% brand-name and 41% 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 100/100 for the 2023 performance year (Quality 100), compared with the national average of 83.1.

Cornea and External Diseases Specialist Physician is a narrow specialty nationwide, with 294 enrolled providers across 43 states and an average of 1,232 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.
