MARIKJE SHREEVE, CNS; PMHNP appears in the CMS NPPES registry as a Psychiatric/Mental Health Nurse Practitioner provider holding CNS; PMHNP credentials at 611 MCDOWELL AVE NW, ROANOKE, VA, 24016, with a listed phone of (540) 266-9200. NPI 1134450067 was issued on 01/15/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SHREEVE 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 1,095 prescription claims written by this provider, covering 54 Medicare beneficiaries and totaling roughly $343K in drug spend, split 11% brand-name and 89% 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.
