CRYSTAL WELLS, NP-C appears in the CMS NPPES registry as a Adult Health Nurse Practitioner provider holding NP-C credentials at 39 BRENTWOOD RD, BAY SHORE, NY, 11706, with a listed phone of (631) 591-7400. NPI 1770009326 was issued on 08/16/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WELLS 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 2,721 prescription claims written by this provider, covering 780 Medicare beneficiaries and totaling roughly $628K in drug spend, split 17% brand-name and 83% 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 91.2532/100 for the 2023 performance year (Quality 74.9203), compared with the national average of 83.1.

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.
