Extends financial support provided under the Program for an additional five years. (Current law allows financial support for a maximum of ten years.)

Amends the Public Health Service Act to revise the requirements of the C.W. Bill Young Cell Transplantation Program to: (1) require studies and projects under such Program to include exploring novel approaches or incentives to expand the number of cord blood unit collection sites partnering with federally-supported cord blood banks; and (2) revise privacy provisions to protect the privacy of patients and donors in accordance with federal and state law. Reauthorizes appropriations for such Program for FY2011-FY2015.

Directs the Comptroller General to submit a report to the relevant congressional committees and the Secretary of Health and Human Services (HHS) that reviews studies, demonstration programs, and outreach efforts to increase  cord blood unit donation and collection.
