KRISTY DARNELL, RN,MSN, FNP-BC, CNRN appears in the CMS NPPES registry as a Neuroscience Registered Nurse provider holding RN,MSN, FNP-BC, CNRN credentials at 200 E 89TH AVE, MERRILLVILLE, IN, 46410, with a listed phone of (218) 738-4930. NPI 1316244528 was issued on 02/24/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DARNELL 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 1,866 prescription claims written by this provider, covering 151 Medicare beneficiaries and totaling roughly $1.5 million in drug spend, split 32% brand-name and 68% generic by claim count, with an opioid prescribing rate of 3.6%. 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 74.6301/100 for the 2023 performance year (Quality 63.0682, Cost 62.4208), compared with the national average of 83.1.

Neuroscience Registered Nurse is a narrow specialty nationwide, with 292 enrolled providers across 43 states and an average of 1,016 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.
