SUSAN CHEN, APNP appears in the CMS NPPES registry as a Diabetes Educator Registered Nurse provider holding APNP credentials at 210 W CAPITOL DR, MILWAUKEE, WI, 53212, with a listed phone of (414) 727-6320. NPI 1265951651 was issued on 09/17/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHEN 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 2,416 prescription claims written by this provider, covering 100 Medicare beneficiaries and totaling roughly $299K in drug spend, split 16% brand-name and 84% generic by claim count, with an opioid prescribing rate of 1.0%. 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.

Diabetes Educator Registered Nurse is a narrow specialty nationwide, with 2,273 enrolled providers across 55 states and an average of 1,296 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
