TAMMY ANDES, APRN appears in the CMS NPPES registry as a Registered Nurse provider holding APRN credentials at 601 W WASHINGTON ST STE 1, NEWTON, IL, 62448, with a listed phone of (618) 783-0954. NPI 1639635972 was issued on 02/12/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ANDES 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 846 prescription claims written by this provider, covering 87 Medicare beneficiaries and totaling roughly $56K in drug spend, split 17% brand-name and 83% generic by claim count, with an opioid prescribing rate of 2.2%. 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 4.8819/100 for the 2023 performance year (Quality 0, Cost 16.273), compared with the national average of 83.1.

Registered Nurse is a high-volume specialty nationwide, with 175,652 enrolled providers across 56 states and an average of 1,000 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
