Home Health & Hospice Customer Service Phone / Fax

Providers are required to use self-service technology, such as the Interactive Voice Response (IVR) system or the myCGS web portal to access claim status and beneficiary eligibility information. Customer Service Representatives (CSRs) will refer providers to these resources when calling for claims status or eligibility information. Exceptions will be made if you experience technical difficulties.

Before calling to speak with a Customer Service Representative (CSR) in the Provider Contact Center (PCC), consider using the Self Service Tools CGS offers.
