MOHAMED HASSAN, DMD MS appears in the CMS NPPES registry as a Periodontics provider holding DMD MS credentials at 858 E SQUANTUM ST, QUINCY, MA, 02171, with a listed phone of (617) 733-7979. NPI 1588854384 was issued on 07/27/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HASSAN 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 105 prescription claims written by this provider, covering 36 Medicare beneficiaries and totaling roughly $459 in drug spend, with an opioid prescribing rate of 12.4%. 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.

Periodontics is a mid-sized specialty nationwide, with 6,061 enrolled providers across 53 states and an average of 264 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.
