Mesoblast Secures Key Medicare Code for Cell Therapy Ryoncil

Mesoblast, a developer of allogeneic cellular medicines, has achieved a significant commercial milestone for its therapy, Ryoncil (remestemcel-L-rknd).

Without it, providers might face billing uncertainties that could discourage the use of a new product. As detailed in the , this development is a key component of Mesoblast's strategy to ensure Ryoncil can reach the vulnerable patient population it is designed to help.
