The provider supplied these details to the public NPPES registry. The import date records when TidyFax obtained the record; it is not a confirmation that the fax line works. A specialty identifies the provider's classification, not the department accepting documents.

Before sending, call the listed office to confirm the fax number and the documents it accepts. Report a correction with this page's address and a public source link; do not include private documents.
