ELIZABETH KOTZEN, MD appears in the CMS NPPES registry as a Pediatric Nephrology Physician provider holding MD credentials at 101 MANNING DRIVE, CHAPEL HILL, NC, 27599, with a listed phone of (919) 966-2561. NPI 1255674412 was issued on 04/05/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KOTZEN 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 1,685 prescription claims written by this provider, covering 112 Medicare beneficiaries and totaling roughly $254K in drug spend, split 12% brand-name and 88% 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.

Pediatric Nephrology Physician is a narrow specialty nationwide, with 723 enrolled providers across 50 states and an average of 97 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.
