Welcome to the RCMG Provider Portal!

Dear RCMG Providers,

Thank you for your continued patience while Change Healthcare has continued to sort through their unfortunate cyber security event and begin to re-establish their connections with various carriers. It has been brought to our attention that Change Healthcare has posted on their website that their system is back up and running with RCMG as of 4/1/2024. Unfortunately, this is not accurate information. RCMG continues to make outreach attempts to Change Healthcare to restore the connection but has yet to be successful.

As previously noted in other communications, claims will be processed as of the receipt date. Should you decide to move forward with transitioning to Office Ally or submitting paper claims, please email providerservices@rcmg.com to request an ERA form after you've completed your agreement with Office Ally. Or you may submit your claims via paper to the RCMG mailing address:

River City Medical Group

PO Box 869145

Plano, Tx. 75086

National Drug Codes

When billing a drug HCPCS code a National Drug code is required by River City Medical Group and the NDC must be a valid/active number as per the FDA for date of service being billed.

Vaccination and immunizations do not require an NDC but if you are going to bill an NDC then it has to be an active NDC on the date of service. 

If you bill an NDC that is not active it will deny with the following:

Claim Adjustment Reason Code: 16 - Claim/service lacks information or has submission/billing error(s).

Remittance Advice Remark Code: M119 - Missing/incomplete/invalid/ deactivated/withdrawn National Drug Code (NDC)

If you get this denial, then you will need to resubmit your claim based on RCMG corrected claim submission process
