Washington Medical Board

The Washington Medical Commission is the state regulatory authority that issues and oversees medical licenses in Washington. For license status verification, disciplinary actions, and medical board certification, visit the official website at https://wmc.wa.gov. While this NPI lookup tool confirms a provider's federal NPPES enrollment, state license verification through the Washington Medical Commission is a separate but equally important step in complete provider credential verification. Both NPPES and state board data should be checked during credentialing workflows.
