CMS Pub. 100-09, ch. 6, § 30.7.9
Replying to Correspondence from Members of Congress
In addition to the guidelines outlined above, MACs shall use the following instructions to respond to
Members of Congress:
A – Sending the Response
Generally, MACs send the original and the courtesy copy of the reply to the Washington, D.C.
office of the Member of Congress. However, if the inquiry came from a home office, MACs
direct the original and the courtesy copy there.
B - Replying to a Letter Signed by More Than One Member of Congress
When replying to a letter signed by more than one Member of Congress, MACs prepare a reply
for each Member and enclose a courtesy copy with each. MACs release the replies to each
Member of Congress at the same time.
MACs state in the opening paragraph that they are sending the same reply to each person who signed
the letter and make an official file copy for each Member of Congress. MACs may use the following in
their final reply:
“Similar information is being sent to (Senator or Representative) (name of Member of Congress) who
also inquired on behalf of (name of provider or beneficiary).”
C - Replying to a Letter Signed by an Employee in a Congressional Office
MACs address replies to the Members of Congress even when staff members sign the inquiries.
D - Replying Directly to a Constituent at the Request of a Member of Congress
When addressing a reply to a constituent, MACs send a courtesy letterhead copy to the Member
of Congress, along with a copy of the constituent’s letter.
E - Replying to an Inquiry from Former Members of Congress
Unless the former Member of Congress requests otherwise, MACs address the reply to the
constituent. The MAC shall send a courtesy copy to the former Member of Congress.

G - Courtesy Copies
MACs prepare a courtesy copy for each congressional response if the congressional office
indicated by telephone or letter it wants one. If the response contains an SSN, MACs must redact
the SSN in the courtesy copy to the congressional office. Document the file if the Member of
Congress indicates they don’t need a copy.
H - Constituent’s Letter
Members of Congress frequently forward the constituent’s letter for assistance in replying.
MACs should return the constituent’s letter, if it’s original, with the first written response unless
it contains an SSN.
When the constituent’s letter is the only enclosure, on the courtesy copy and all other copies of the reply
(but NOT ON ORIGINAL), the MAC shall type:
