ELIZABETH MARSHALL, MD appears in the CMS NPPES registry as a Surgical Critical Care Physician provider holding MD credentials at 2001 MEDICAL PKWY, ANNAPOLIS, MD, 21401, with a listed phone of (443) 481-4142. NPI 1215593710 was issued on 05/10/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MARSHALL 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 43 prescription claims written by this provider, covering 25 Medicare beneficiaries and totaling roughly $332 in drug spend, with an opioid prescribing rate of 46.5%. 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.

Surgical Critical Care Physician is a narrow specialty nationwide, with 1,468 enrolled providers across 53 states and an average of 86 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.
