CUSIP No. 40425J101

ITEM 1. SECURITY AND ISSUER

This Amended Statement on Schedule 13D (the "Statement") relates to the Common
Stock, par value $0.01 per share, of HMS Holdings Corp., a New York corporation
(the "Company"). The address of the Company's principal executive office is 401
Park Avenue South, New York, NY 10016.

ITEM 2. IDENTITY AND BACKGROUND

(a) This Statement is being filed jointly by Public Consulting Group, Inc.
("PCG") and William S. Mosakowski, in his capacity as the President, Chief
Executive Officer, controlling stockholder and member of the Board of Directors
of PCG. PCG is a corporation organized under the laws of the Commonwealth of
Massachusetts. Mr. Mosakowski and PCG are each referred to herein individually
as a "Reporting Person" and collectively as the "Reporting Persons."

The executive officers of PCG are Mr. Mosakowski (President and Chief Executive
Officer) and Daniel T. Heaney (Chief Financial Officer). The Board of Directors
of PCG consists of Mr. Mosakowski, Stephen Skinner, T. McLean Brown, Marc H.
Fenton, and Benjamin Bobo.

(b) The business address of the Reporting Persons and the other individuals
listed in Item 2(a) above (collectively, the "Item 2 Persons") is 148 State
Street, Tenth Floor, Boston, Massachusetts 02109.

(c) PCG is a management consulting firm offering public policy development,
service delivery and design, rate setting, cost accounting, revenue
maximization, financial management, operations improvement, planning, strategy
implementation and other management advisory services to government and private
health and human service providers. As described in Item 2(a), Mr. Mosakowski is
the President and Chief Executive Officer of PCG.

(d) During the last five years, none of the Item 2 Persons have been convicted
in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, none of the Item 2 Persons have been party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
and as a result of such proceeding were or are subject to a judgment, decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

(f) Messrs. Mosakowski, Heaney, Skinner, Brown, Fenton, and Bobo are citizens of
the United States.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

(a) On September 14, 2007, PCG sold 1,000,000 shares of the Company's common
stock pursuant to a registration statement on Form S-3 that was declared
effective on February 21, 2007. Consequently, as of the date of this filing, PCG


                                       4


owns 749,800 shares of the Company's common stock, par value $0.01 per share,
which represents approximately 3.2% of the Company's outstanding shares of
common stock. This percentage assumes 23,581,243 shares of common stock
outstanding as of August 7, 2007, as disclosed in the Company's most recent
Quarterly Report on Form 10-Q filed August 7, 2007. Because PCG no longer owns
more than five percent of any class of securities issued by the Company, PCG is
not required to amend this filing unless it hereafter becomes the beneficial
owner of more than five percent of such a class of securities.

Messrs. Mosakowski, Heaney, Skinner, Brown, and Fenton do not own of record any
shares of the Company's common stock ("Common Stock"). As described more fully
in Item 5(b) below, Mr. Bobo owns of record 20,000 shares of the Company's
Common Stock, which shares are not included in the Shares reported in Items 7
and 10 above. Messrs. Mosakowski and Heaney, as officers of PCG, Messrs.
Mosakowski, Skinner, and Brown, as significant shareholders of PCG, and Messrs.
Mosakowski, Skinner, Brown, Fenton, and Bobo, as members of PCG's Board of
Directors, may be deemed to beneficially own shares of Common Stock beneficially
owned by PCG. Except to the extent of his interest as an officer, stockholder,
or member of the Board of Directors, each of Messrs. Mosakowski, Heaney,
Skinner, Brown, Fenton, and Bobo expressly disclaims such beneficial ownership,
and the filing of this statement shall not be construed as an admission that
such person is the beneficial owner of the Shares owned by PCG and covered by
this Statement. PCG and each of Messrs. Mosakowski, Heaney, Skinner, Brown, and
Fenton expressly disclaims beneficial ownership of the shares of Common Stock
owned of record by Mr. Bobo, and the filing of this statement shall not be
construed as an admission that such person is the beneficial owner of such
shares.

(b) PCG has the sole power to vote or direct the vote, and to dispose or direct
the disposition of the Shares. By virtue of the facts described in Item 5(a)
above, Messrs. Mosakowski, Heaney, Skinner, Brown, Fenton, and Bobo may be
deemed to share in the indirect power to vote and direct the disposition of the
Shares. Mr. Bobo has the sole power to vote or direct the vote, and to dispose
or direct the disposition of 20,000 shares of the Company's Common Stock.

(c) No other person is known to have the right to receive or the power to direct
the receipt of dividends from, or the proceeds from the sale of Shares reported
on this Statement.

(d) Not applicable.
