AGATHA KOCH, FNP, RNFA appears in the CMS NPPES registry as a Registered Nurse First Assistant provider holding FNP, RNFA credentials at 51 E 25TH STREET 6TH FLOOR, NEW YORK, NY, 10010, with a listed phone of (212) 813-3632. NPI 1861820342 was issued on 10/22/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KOCH 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 431 prescription claims written by this provider, covering 150 Medicare beneficiaries and totaling roughly $162K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 26.7%. 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.

Registered Nurse First Assistant is a narrow specialty nationwide, with 2,649 enrolled providers across 50 states and an average of 419 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.
