TESSA DEBELLIS, PA-C appears in the CMS NPPES registry as a Assistant Behavior Analyst provider holding PA-C credentials at 6900 E 10 MILE RD, CENTER LINE, MI, 48015, with a listed phone of (586) 756-7777. NPI 1316456569 was issued on 09/20/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DEBELLIS 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 1,014 prescription claims written by this provider, covering 162 Medicare beneficiaries and totaling roughly $81K in drug spend, split 16% brand-name and 84% 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.

Assistant Behavior Analyst is a mid-sized specialty nationwide, with 9,660 enrolled providers across 51 states and an average of 1,271 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.
