Agencies served by CGS should beware this mistake commonly made by providers under medical review. “Do not use the ‘Submit Inquiry’ button to send medical records in response to our request for additional documentation (ADR)” on the myCGS system, the HHH Medicare Administrative Contractor stresses in a message to providers. “You must use the ‘Submit Documents’ button in order for your documentation to correctly index to your pending claim.” Watch for: “If the time limit to respond to the ADR has passed, the ‘Submit Documents’ button will be grayed,” CGS adds. “Your only option in this case is to request a Redetermination.” Bottom line: “The ‘Submit Inquiry’ button is available ONLY to ask general questions,” CGS emphasizes.
