Benjamin Ehrenreich appears in the CMS NPPES registry as a Addiction Psychiatry Physician provider at 6501 N CHARLES ST, Baltimore, MD, 21204, with a listed phone of (410) 938-4811. NPI 1285029199 was issued on 03/30/2015.

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 Addiction Psychiatry Physician providers operate outside Part D entirely.

Addiction Psychiatry Physician is a narrow specialty nationwide, with 667 enrolled providers across 49 states and an average of 792 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
