Medicare Administrative Contractors are alerting providers to a claims processing error that is causing rejections because the Common Working File (CWF) incorrectly identifies some beneficiaries as being incarcerated.
 
CMS is researching to determine how to correct the incarceration date for impacted beneficiaries and process claims that rejected in error, CGS noted in a message to providers Aug. 15, 2024.
 
Palmetto GBA said it was suspending affected claims and NOAs to “status/location (S/LOC) S MOSUI until the issue is resolved,” according to an Aug. 28, 2024, update.
 
No action is needed at this time, Palmetto noted. “Some claims and notices may have been rejected prior to the implementation of the suspension. Correcting the rejections will be part of the resolution.”
