Victoria Siemion, MSN, CRNP, FNP-BC appears in the CMS NPPES registry as a Family Nurse Practitioner provider holding MSN, CRNP, FNP-BC credentials at 860 1ST AVE, King Of Prussia, PA, 19406, with a listed phone of (610) 265-1166. NPI 1821732181 was issued on 04/23/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Siemion 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 197 prescription claims written by this provider, covering 83 Medicare beneficiaries and totaling roughly $6K 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 77.1/100 for the 2023 performance year, compared with the national average of 83.1.

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.
