The "Listed PSO" logo is available for use by PSOs that are currently listed by the HHS Secretary. Health care providers considering working with a PSO are advised to review this directory to ensure that the entity's PSO certifications have been accepted in accordance with 
The “AHRQ Common Formats” logo may be displayed by any organization that is using the Common Formats developed by AHRQ. Please note that an entity does not need to be listed as a PSO to use the Common Formats and thus display the logo. The Formats are available in the public domain to facilitate their widespread adoption and implementation. Entities that display the logo should use the Common Formats as a whole; however, entities that have a limited focus may display the logo when using Common Formats that pertain only to that area.
