Maryland Healthcare Provider Overview
Healthcare in Maryland is served by a network of providers across major cities including Baltimore, Frederick, Rockville, Gaithersburg, Bowie. Maryland providers span all medical specialties — from primary care physicians and family medicine to specialized surgical centers, behavioral health providers, and long-term care facilities. All providers who accept insurance, bill Medicare or Medicaid, or participate in electronic health record systems are listed in the NPPES NPI registry with active NPI records.
Maryland Medical Board
The Maryland Board of Physicians is the state regulatory authority that issues and oversees medical licenses in Maryland. For license status verification, disciplinary actions, and medical board certification, visit the official website at https://www.mbp.state.md.us. While this NPI lookup tool confirms a provider's federal NPPES enrollment, state license verification through the Maryland Board of Physicians is a separate but equally important step in complete provider credential verification. Both NPPES and state board data should be checked during credentialing workflows.

Healthcare providers in Maryland cover the full spectrum of medical specialties. The most commonly registered specialties in the NPPES registry for Maryland include internal medicine, family medicine, general surgery, pediatrics, obstetrics and gynecology, cardiology, orthopedics, psychiatry, neurology, and radiology.
