UMLS Licensing

NLM (National Library of Medicine) provides clinical vocabulary standards and tools that support implementation of Meaningful Use, C-CDA, and other programs. These standards and tools are provided via a set of files and software called the UMLS (Unified Medical Language System).

A license is required to browse and download files. UMLS licenses are

  • free
  • issued only to individuals and not to groups or organizations
  • each person in your organization should request their own license here.

Requesting a UMLS License and creating a UTS account is a two-step process

  1. Submit your license request.
  2. Authenticate the request after receipt of e-mail from NLM.

License Requests are processed on weekdays between 9am – 5pm US Eastern Time. It may take up to 3 business days from the time you authenticate your request to approve your request depending on the volume of requests in the system.
