The undersigned, Edson de Godoy Bueno, hereby authorizes and
designates each of Marianne D. Short, Dannette L. Smith, Richard J.
Mattera and Amy L. Schneider, or any of them, acting singly with full
power of substitution (each, an "attorney-in-fact"), to sign and file
on the undersigned's behalf the Form ID in order to obtain or manage
EDGAR filing codes, and any Forms 3, 4, 5 or 144 (including any
amendments thereto) that the undersigned may be required to file with
the Securities and Exchange Commission as a result of the undersigned's
ownership of or transactions in securities of UnitedHealth Group
Incorporated (the "Company") at any date following the date hereof.
The authority of each attorney-in-fact under this Power of Attorney
will continue until the undersigned is no longer required to file Forms
3, 4, 5 or 144 with regard to the undersigned's ownership of or
transactions in securities of the Company, unless earlier revoked in

with regard to Company securities as of the date hereof, except that if
the undersigned has adopted any Rule 10b5-1 trading plan to transact in
Company securities, any powers of attorney the undersigned may have
granted under the plan to sign or file on the undersigned's behalf any
Form 144 shall continue to be in full force and effect in accordance
with the terms of the plan.  The undersigned acknowledges that neither
the Company nor an attorney-in-fact are assuming any of the
undersigned's responsibilities to comply with Section 16 of the
Securities Exchange Act of 1934 or Rule 144 under the Securities Act
of 1933.
