Medicare Administrative Contractor (MAC) NGS has identified a claims processing issue involving claims for several immunization and administration procedures codes being incorrectly denied due to an incorrect diagnosis code.
 
Affected codes are: G0008, G0010, G0009, 90630, 90669, 90670, 90686, 90732, 90739, 90740, 90743, 90744, 90746 and 90747.
 
“A mass adjustment will be made to claims that denied in error; adjustments will be completed soon,” an NGS release states. “It is unnecessary to resubmit the claim or to request an appeal. No provider action is needed.”
