KEITH ARMSTRONG, NP-C appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding NP-C credentials at 1300 W TERRELL AVE STE 500, FORT WORTH, TX, 76104, with a listed phone of (817) 252-5000. NPI 1750816989 was issued on 04/25/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ARMSTRONG 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Acute Care Nurse Practitioner providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 75.2752/100 for the 2023 performance year (Quality 68.0792, Cost 49.5048), compared with the national average of 83.1.

Acute Care Nurse Practitioner is a mid-sized specialty nationwide, with 24,583 enrolled providers across 53 states and an average of 576 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.
