If the revalidation notification letter is returned to South Carolina Healthy Connections Medicaid as undeliverable mail, we will call you using the phone number on file in order to update your address. You will need to follow the standard procedure to update your address. 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.

If you are unable to be reached using the phone number on file, your inability to complete the provider revalidation process means that you have voluntarily terminated as a South Carolina Healthy Connections Medicaid provider and will need to enroll as a new provider.
