CHERI MARMAROSH, PH.D. appears in the CMS NPPES registry as a Counseling Psychologist provider holding PH.D. credentials at 4601 CONNECTICUT AVENUE, WASHINGTON, DC, 20008, with a listed phone of (301) 718-0444. NPI 1700099124 was issued on 05/08/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MARMAROSH 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Counseling Psychologist providers operate outside Part D entirely.

Counseling Psychologist is a mid-sized specialty nationwide, with 7,896 enrolled providers across 54 states and an average of 744 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.
