Jill Tesei, A.P.R.N. appears in the CMS NPPES registry as a Mental Health Counselor provider holding A.P.R.N. credentials at 399 EAST PUTNAM AVE., Cos Cob, CT, 06807, with a listed phone of (203) 906-6016. NPI 1306043062 was issued on 06/27/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Tesei 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 36 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $334 in drug spend. 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.

Mental Health Counselor is a high-volume specialty nationwide, with 292,612 enrolled providers across 55 states and an average of 1,063 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.
