MARISSA SINSABAUGH appears in the CMS NPPES registry as a Emergency Registered Nurse provider at 323 SW 10TH ST, MADISON, SD, 57042, with a listed phone of (605) 256-6551. NPI 1376210179 was issued on 08/27/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SINSABAUGH 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 229 prescription claims written by this provider, covering 149 Medicare beneficiaries and totaling roughly $5K in drug spend, split 5% brand-name and 95% generic by claim count, with an opioid prescribing rate of 8.7%. 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 90.1851/100 for the 2023 performance year (Quality 86.6937, Cost 91.6787), compared with the national average of 83.1.

Emergency Registered Nurse is a narrow specialty nationwide, with 4,284 enrolled providers across 54 states and an average of 710 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.
