MICHAEL LAFERNEY, CNS appears in the CMS NPPES registry as a Clinical Nurse Specialist provider holding CNS credentials at 100 LEDGEWOOD PL, ROCKLAND, MA, 02370, with a listed phone of (781) 871-6550. NPI 1942346531 was issued on 01/30/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LAFERNEY 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 1,738 prescription claims written by this provider, covering 46 Medicare beneficiaries and totaling roughly $112K in drug spend, split 2% brand-name and 98% 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 25.7926/100 for the 2023 performance year (Quality 0, Cost 85.9752), compared with the national average of 83.1.

Clinical Nurse Specialist is a narrow specialty nationwide, with 1,708 enrolled providers across 49 states and an average of 953 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.
