MARIELLE MITCHELL, NP-C appears in the CMS NPPES registry as a Family Nurse Practitioner provider holding NP-C credentials at 1555 BARRINGTON RD STE 2550, HOFFMAN ESTATES, IL, 60169, with a listed phone of (847) 250-2487. NPI 1063187615 was issued on 08/14/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MITCHELL 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 3,410 prescription claims written by this provider, covering 420 Medicare beneficiaries and totaling roughly $205K in drug spend, split 4% brand-name and 96% generic by claim count, with an opioid prescribing rate of 67.0%. 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.

Family Nurse Practitioner is a high-volume specialty nationwide, with 209,817 enrolled providers across 56 states and an average of 1,222 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.
