RACHEL REJNIAK, AGPCNP-BC appears in the CMS NPPES registry as a Gerontology Nurse Practitioner provider holding AGPCNP-BC credentials at 3113 SAEMANN AVE, SHEBOYGAN, WI, 53081, with a listed phone of (920) 496-4700. NPI 1003537150 was issued on 09/07/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what REJNIAK 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 2,669 prescription claims written by this provider, covering 194 Medicare beneficiaries and totaling roughly $147K in drug spend, with an opioid prescribing rate of 10.9%. 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.

Gerontology Nurse Practitioner is a mid-sized specialty nationwide, with 9,625 enrolled providers across 54 states and an average of 1,283 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.
