ELVIRA USINOWICZ, APN,C. appears in the CMS NPPES registry as a Critical Care Medicine Clinical Nurse Specialist provider holding APN,C. credentials at 223 N VAN DIEN AVE, RIDGEWOOD, NJ, 07450, with a listed phone of (201) 447-8000. NPI 1427328277 was issued on 01/11/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what USINOWICZ 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 777 prescription claims written by this provider, covering 171 Medicare beneficiaries and totaling roughly $503K in drug spend, split 23% brand-name and 77% 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 98.6738/100 for the 2023 performance year (Quality 93.5705), compared with the national average of 83.1.

Critical Care Medicine Clinical Nurse Specialist is a narrow specialty nationwide, with 211 enrolled providers across 34 states and an average of 963 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
