DARBY LONG, MSN, APRN, FNP-C appears in the CMS NPPES registry as a Family Nurse Practitioner provider holding MSN, APRN, FNP-C credentials at 1 CELLINI PL STE 102, WEST HAVEN, CT, 06516, with a listed phone of (203) 932-6481. NPI 1831856137 was issued on 11/21/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LONG 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 1,173 prescription claims written by this provider, covering 189 Medicare beneficiaries and totaling roughly $89K in drug spend, with an opioid prescribing rate of 6.1%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 90.7483/100 for the 2023 performance year (Quality 82.2742, Cost 58.9275), compared with the national average of 83.1.

Family Nurse Practitioner is a high-volume specialty nationwide, with 209,817 enrolled providers across 56 states and an average of 1,222 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
