GRACE HERWIG, RN, APN appears in the CMS NPPES registry as a Adult Psychiatric/Mental Health Clinical Nurse Specialist provider holding RN, APN credentials at 26027 COBBLESTONE WAY, WESTLAKE, OH, 44145, with a listed phone of (440) 360-9306. NPI 1740476548 was issued on 09/15/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HERWIG 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 1,270 prescription claims written by this provider, covering 58 Medicare beneficiaries and totaling roughly $115K in drug spend, split 5% brand-name and 95% 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.

Adult Psychiatric/Mental Health Clinical Nurse Specialist is a narrow specialty nationwide, with 953 enrolled providers across 51 states and an average of 1,309 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.
