DEVAN COSTELLE, RN, APRN, AGACNP-BC appears in the CMS NPPES registry as a Gerontology Nurse Practitioner provider holding RN, APRN, AGACNP-BC credentials at 201 ABRAHAM FLEXNER WAY, LOUISVILLE, KY, 40202, with a listed phone of (502) 718-2877. NPI 1962055319 was issued on 07/24/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what COSTELLE 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 120 prescription claims written by this provider, covering 31 Medicare beneficiaries and totaling roughly $18K in drug spend, split 11% brand-name and 89% generic by claim count. 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 73.1977/100 for the 2023 performance year (Quality 58.7401, Cost 51.919), compared with the national average of 83.1.

Gerontology Nurse Practitioner is a mid-sized specialty nationwide, with 9,625 enrolled providers across 54 states and an average of 1,283 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
