AMY MUELLER, AGNP appears in the CMS NPPES registry as a Adult Health Nurse Practitioner provider holding AGNP credentials at 4921 PARKVIEW PL, SAINT LOUIS, MO, 63110, with a listed phone of (314) 362-1291. NPI 1154606325 was issued on 10/19/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MUELLER 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 1,448 prescription claims written by this provider, covering 363 Medicare beneficiaries and totaling roughly $303K in drug spend, split 20% brand-name and 80% 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 79.292/100 for the 2023 performance year (Quality 71.46, Cost 59.5132), compared with the national average of 83.1.

Adult Health Nurse Practitioner is a mid-sized specialty nationwide, with 29,492 enrolled providers across 55 states and an average of 1,201 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.
