CYLLENE SAINTELIEN, PMHNP-BC, NP appears in the CMS NPPES registry as a Mental Health Counselor provider holding PMHNP-BC, NP credentials at 124 LONG POND RD STE 11B, PLYMOUTH, MA, 02360, with a listed phone of (617) 202-3003. NPI 1174715957 was issued on 08/15/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SAINTELIEN 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 789 prescription claims written by this provider, covering 45 Medicare beneficiaries and totaling roughly $110K 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.

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.
