SARAH BLOCH, RN, MSN, FNP appears in the CMS NPPES registry as a General Practice Registered Nurse provider holding RN, MSN, FNP credentials at 15740 S OUTER 40 RD, CHESTERFIELD, MO, 63017, with a listed phone of (636) 237-4700. NPI 1043506256 was issued on 06/26/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BLOCH 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 3,602 prescription claims written by this provider, covering 316 Medicare beneficiaries and totaling roughly $269K in drug spend, split 10% brand-name and 90% 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.

General Practice Registered Nurse is a mid-sized specialty nationwide, with 5,478 enrolled providers across 55 states and an average of 1,187 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.
