Palmetto GBA has recently seen an influx of misrouted Additional Documentation Request (ADRs) and other documentation from providers, according to an alert on the Medicare Administrative Contractor’s (MAC) website.
 
“Providers are sending documents without coversheets, ADR letters, and/or sending them to the incorrect department. Sending your documentation this way will delay processing,” Palmetto noted.
 
The MAC suggests carefully reviewing your letter before responding to the ADR.
