HALEY MARTIN, AGPCNP-BC appears in the CMS NPPES registry as a Gerontology Registered Nurse provider holding AGPCNP-BC credentials at 22915 FAIRLEAF CIR, KATY, TX, 77494, with a listed phone of (254) 541-0443. NPI 1629711783 was issued on 04/17/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MARTIN 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 2,024 prescription claims written by this provider, covering 95 Medicare beneficiaries and totaling roughly $163K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 0.5%. 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.

Gerontology Registered Nurse is a narrow specialty nationwide, with 749 enrolled providers across 48 states and an average of 1,721 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.
