CMS Pub. 100-09, ch. 6, § 30.7.1
Controlling Provider Written Inquiries
MACs shall control all provider written inquiries until they’re closed by the written inquiry unit.
Consider a written inquiry closed upon
• Release of the final response
• Transfer of the inquiry to another department within the MAC
• Rerouting of the inquiry to the appropriate external entity
The corporate mailroom shall forward provider written inquiries, except for misrouted inquiries, to the
PCC’s written inquiry unit for processing and control. MACs shall stamp the cover page of all provider
written inquiries and the top page of all attachments with the date of receipt in the corporate mailroom.
Electronic inquiries with system-generated date stamps don’t require an additional corporate date stamp.
However, electronic inquiries received after the close of a MAC’s normal business day shall be date-stamped the next business day. For provider inquiry timeliness purposes, count the date of receipt as
day one.
MACs aren’t required to keep the incoming envelope but those who do shall ensure the envelope,
incoming correspondence, and the top page of all attachments are date-stamped in the corporate
mailroom.
