Medicare Administrative Contractor CGS is reporting a new claims processing issue that is causing certain claims to be erroneously returned to the provider.
 
Beginning on Jan. 2, 2024, EMS claims submitted on type of bill 329 were returned with reason code 31175, according to the CGS alert.
 
The reason is due to the values loaded into the iQIES system not populating in the FISS.
 
A system update is scheduled for Feb. 12, 2024, CGS notes.
