MARTHA GREER, NP appears in the CMS NPPES registry as a Adult Health Nurse Practitioner provider holding NP credentials at 500 VILLAGE BLVD STE C, MCALESTER, OK, 74501, with a listed phone of (918) 302-0700. NPI 1427563428 was issued on 12/12/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GREER 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 685 prescription claims written by this provider, covering 324 Medicare beneficiaries and totaling roughly $71K in drug spend, split 11% brand-name and 89% generic by claim count, with an opioid prescribing rate of 16.4%. 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.

Adult Health Nurse Practitioner is a mid-sized specialty nationwide, with 29,492 enrolled providers across 55 states and an average of 1,201 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.
