KARYN BUTLER, FPMHNP-BC appears in the CMS NPPES registry as a Psychiatric/Mental Health Nurse Practitioner provider holding FPMHNP-BC credentials at 2111 UNIVERSITY PARK DR STE 400, OKEMOS, MI, 48864, with a listed phone of (517) 258-0180. NPI 1043763741 was issued on 07/28/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BUTLER 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 2,396 prescription claims written by this provider, covering 102 Medicare beneficiaries and totaling roughly $396K in drug spend, split 6% brand-name and 94% 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.

Psychiatric/Mental Health Nurse Practitioner is a mid-sized specialty nationwide, with 39,953 enrolled providers across 54 states and an average of 927 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.
