POWER OF ATTORNEY                                                Exhibit 24


The undersigned, Andrew P. Witty, hereby authorizes and designates each of
Marianne D. Short, Dannette L. Smith and Faraz Choudhry, 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 and 144 with
regard to the undersigned's ownership of or transactions in securities of the
Company, unless earlier revoked in writing.  The undersigned hereby revokes
all previous powers of attorney to sign or file on the undersigned's behalf
any Forms 3, 4, 5 or 144 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 is 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.
