MARCELLA ROWLEY, FNP appears in the CMS NPPES registry as a Primary Care Nurse Practitioner provider holding FNP credentials at 1420 W 12600 S STE 102, RIVERTON, UT, 84065, with a listed phone of (801) 254-4600. NPI 1740301837 was issued on 04/03/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ROWLEY 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 6,395 prescription claims written by this provider, covering 282 Medicare beneficiaries and totaling roughly $773K in drug spend, split 18% brand-name and 82% generic by claim count, with an opioid prescribing rate of 5.1%. 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.

Primary Care Nurse Practitioner is a mid-sized specialty nationwide, with 10,138 enrolled providers across 54 states and an average of 1,363 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.
