WHAT THE BILL DOES
AI-writtenThis bill matters because it ensures that critical, life-saving medical programs do not expire or run out of funding. Without this reauthorization, the national system that helps patients find matching bone marrow donors or cord blood units for stem cell transplants could be significantly disrupted. This would make it much harder for individuals with severe diseases, such as certain cancers and genetic blood disorders, to get the treatment they need.
If this bill becomes law, patients will continue to have access to a robust national registry and inventory, improving their chances of finding a compatible donor. If it doesn't pass, these programs would cease to exist or operate with significantly reduced capacity after 2026, potentially leading to fewer successful transplants and worse outcomes for patients in desperate need of this therapy.
KEY PROVISIONS
3AI-extractedPROVISION 01
Reauthorizes the C.W. Bill Young Cell Transplantation Program, which manages a national registry of bone marrow and cord blood donors and facilitates transplants.
This ensures the continued operation of a vital system for matching patients with life-saving stem cell transplants.
PROVISION 02
Authorizes $33,009,000 annually for the C.W. Bill Young Cell Transplantation Program for fiscal years 2027 through 2031.
This provides the necessary funding to sustain the program's operations for another five years, supporting patient access to care.
PROVISION 03
Extends the authority for the Cord Blood Inventory program from 2026 to 2031.
This ensures the continued collection and storage of umbilical cord blood for public use, expanding the pool of available stem cells for transplants.
