The CMS National Plan and Provider Enumeration System currently lists 8,326 Clinical Social Worker providers with a primary practice address in Maryland, all registered under the Social Worker NUCC taxonomy branch. Each clinician on this roster selected Clinical Social Worker as their primary taxonomy at NPI enrollment — a self-reported classification that is updated whenever the provider files a correction with CMS. The count excludes organizations (group practices, hospitals, clinics operate under separate NPIs) and excludes providers who chose a different primary specialty even if they practice Clinical Social Worker part-time. Every figure is drawn from the federal National Provider Identifier Registry (CMS NPPES) — more than 7 million providers, maintained since May 2007, with 2023 Medicare Part D data — and, according to CMS, can be searched, compared, and traced in our methodology.

At 8,326 enrolled providers, Clinical Social Worker in Maryland is a very well-covered market — that matters for search-radius decisions, because patients in Maryland outside the largest metros often need to broaden to adjacent cities to find a local Clinical Social Worker clinician. The directory below is paginated 50 providers at a time (167 pages total) and is sorted alphabetically by last name, so scanning for a specific practice usually goes faster than scrolling; on the provider detail page you'll find the full NPPES record including address, phone, credentials, and any published Medicare Part D prescribing activity for 2023.

Before contacting anyone on this list, verify the practice is still at the address shown — NPPES refreshes monthly, but providers who have relocated, retired, or changed employers may not have filed an NPI update yet. Important: PlainDoctor is a directory of publicly available CMS government data covering Clinical Social Worker providers in Maryland, not a quality ranking, a board-certification verifier, or medical advice. Always confirm credentials through the NPPES NPI Registry, the Maryland medical board, and — where relevant — the ABMS, AOA, or the specialty's primary certifying body before making any clinical decision. Nothing on this page substitutes for a conversation with a licensed clinician.
