Contact the South Carolina Healthy Connections Medicaid Provider Service Center at 888-289-0709, option 4. It is your responsibility to ensure that your contact information is current. Customer Service Advocates cannot update your address information over the phone.

To update your address, please fax or mail a letter requesting an address change to MCCS Provider Enrollment on company letterhead. The Provider Enrollment fax number is (803) 870-9022. The address is Medicaid Provider Enrollment, P.O. Box 8809, Columbia, SC 29202-8809. The letter should include the provider’s legacy and NPI numbers, as well as the new address, along with the provider’s or an authorized person’s signature and a contact person’s name and telephone number in case there are any questions. Once the address information is updated and the revalidation notification letter is re-sent, the provider will still have 30 days from the date on the original revalidation notification letter to fully complete the provider revalidation process.
