Gregory Bassmann, MD appears in the CMS NPPES registry as a Pulmonary Disease Physician provider holding MD credentials at 6565 N CHARLES ST, Baltimore, MD, 21204, with a listed phone of (443) 849-3901. NPI 1174781611 was issued on 05/31/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Bassmann 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 901 prescription claims written by this provider, covering 143 Medicare beneficiaries and totaling roughly $375K in drug spend, split 68% brand-name and 32% 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.

Pulmonary Disease Physician is a mid-sized specialty nationwide, with 9,271 enrolled providers across 53 states and an average of 1,457 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
