ERIN BOUMANSOUR, ACNP appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding ACNP credentials at 2366 OAK VALLEY DR, ANN ARBOR, MI, 48103, with a listed phone of (877) 227-8823. NPI 1023311057 was issued on 12/14/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BOUMANSOUR 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 194 prescription claims written by this provider, covering 54 Medicare beneficiaries and totaling roughly $12K in drug spend, split 8% brand-name and 92% generic by claim count, with an opioid prescribing rate of 44.3%. 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.

Acute Care Nurse Practitioner is a mid-sized specialty nationwide, with 24,583 enrolled providers across 53 states and an average of 576 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.
