Palmetto GBA, California's Medicare contractor, has advised the California Medical Association that some claims filed in early January were mistakenly rejected because of a failure to load the 2013 zip code file into Palmetto's computer system.

According to Palmetto, the erroneously rejected claims (MA130) would have included message code MA114 (Missing/incomplete/invalid information on where the services were furnished) and with dates of service of January 2-4, 2013.

Palmetto will automatically adjust affected claims beginning January 28, 2013. Physicians may resubmit their claims or wait for the claims to be reprocessed.
