Know all by these present, that the undersigned hereby constitutes and
appoints Jonathan Olefson, Bradley Ferguson and Sara Epstein, or any one
of them signing singly, and with full power of substitution, the
undersigned's true and lawful attorney-in-fact to:

(1)   execute for and on behalf of the undersigned, in the undersigned's
capacity as an officer and/or director of Cotiviti Holdings, Inc.
(the "Company") or as a stockholder of the Company or as a trustee of a
stockholder of the Company, Forms 3, 4, and 5 and Schedules 13D or 13G,
including amendments thereto, relating to the securities of the Company
in accordance with Section 16(a) of the Securities Exchange Act of 1934
and the rules thereunder;

(2)   do and perform any and all acts for and on behalf of the undersigned
which may be necessary or desirable to complete and execute any such Form
3, 4, or 5 or Schedule 13D or 13G, complete and execute any amendment or
amendments thereto, and timely file such form with the United States
Securities and Exchange Commission and any stock exchange or similar
authority; and

(3)   take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required by, the undersigned, it
being understood that the documents executed by such attorney-in-fact on
behalf of the undersigned pursuant to this Power of Attorney shall be in
such form and shall contain such terms and conditions as such
attorney-in-fact may approve in such attorney-in-fact's discretion.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and
powers herein granted, as fully to all intents and purposes as the undersigned
might or could do if personally present, with full power of substitution or
revocation, hereby ratifying and confirming all that such attorney-in-fact,
or such attorney-in-fact's substitute or substitutes, shall lawfully do or
cause to be done by virtue of this Power of Attorney and the rights and powers
herein granted.  The undersigned acknowledges that the foregoing
attorneys-in-fact, in serving in such capacity at the request of the
undersigned, are not assuming, nor is the Company assuming, any of the
undersigned's responsibilities to comply with, or liabilities that may arise
under, Section 16 of the Securities Exchange Act of 1934.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 or Schedules 13D
or 13G with respect to the undersigned's holdings of and transactions in
securities issued by the Company, unless earlier revoked by the undersigned
in a signed writing delivered to the foregoing attorneys-in-fact.

This Power of Attorney shall not revoke any powers of attorney previously
executed by the undersigned.  This Power of Attorney shall not be revoked by
any subsequent power of attorney that the undersigned may execute, unless
such subsequent power of attorney specifically provides that it revokes this
Power of Attorney by referring to the date of the undersigned's execution of
this Power of Attorney.
