Marisa Schrum, FNP-BC appears in the CMS NPPES registry as a Family Nurse Practitioner provider holding FNP-BC credentials at 1890 SILVER CROSS BLVD STE 260, New Lenox, IL, 60451, with a listed phone of (157) 178-7448. NPI 1235618927 was issued on 08/13/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Schrum 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 406 prescription claims written by this provider, covering 98 Medicare beneficiaries and totaling roughly $26K in drug spend, split 10% brand-name and 87% 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.

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.
