Colorado Open Records Act (CORA)

Alert: Due to the March 2020 Work-from-Home Executive Order issued by Governor Polis, the Department asks that CORA requests be submitted via email or portal if possible. CORA requests submitted by regular mail or fax may be delayed.

The Colorado Open Records Act (CORA) allows the public to inspect public records held by the state government. A person who wishes access to open (public) records held by this Department should send a written request by letter, fax, portal or email to:

CORA Officer

CORA Public Records Portal

The CORA Officer will respond and advise you when the requested records will be available for your inspection. Records are usually available within three days. The three-day timeframe begins when the CORA officer or custodian receives the request (see CORA FAQs for more information). You may also request a copy of the records. The following fees may apply:

  • $0.25 per page for copies
  • $20 per hour for research exceeding two hours

If, by prior arrangement, you elect to receive copies of requested documents, you may pay in advance by cash or check payable to the Department of Health Care Policy & Financing. You may pay by credit card if you create an account and submit your request through the portal. We require payment prior to receiving copies of documents.
