HEATHER HAMMAKER, FNP appears in the CMS NPPES registry as a Inpatient Obstetric Registered Nurse provider holding FNP credentials at 865 W LAKE DR, MOUNT AIRY, NC, 27030, with a listed phone of (336) 719-6100. NPI 1952877938 was issued on 10/17/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HAMMAKER 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 4,142 prescription claims written by this provider, covering 414 Medicare beneficiaries and totaling roughly $444K in drug spend, split 14% brand-name and 86% generic by claim count, with an opioid prescribing rate of 3.4%. 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.

Inpatient Obstetric Registered Nurse is a narrow specialty nationwide, with 566 enrolled providers across 52 states and an average of 705 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.
