11. Diagnostic RP Reimbursement Advocacy  Separate Medicare payment for dRPs in hospital outpatient (most important setting for using RPs) was discontinued by CMS in 2008  Separate Medicare payment for dRPs continues in physician offices  Since 2008 LMI, CORAR, and medical societies continued strong advocacy with CMS to restore separate Medicare payment for dRPs in HO setting to maintain patient access to newer and better dRPs.  Increased cost of Mo-99 and Tc-99m is another very important reason for restoring such separate payment for dRPs in HO  CMS/CORAR meeting of 7/26/2011 indicated that Congressional action may be necessary in order to restore separate Medicare payment for dRPs in hospital outpatient setting

12. LMI Mo-99 Leadership  Secure, reliable, globally diversified supply chain, focused on reactors and processors  NRU, SAFARI, BR2, OSIRIS, HFR, LVR-15  Nordion, NTP, IRE, ANSTO  Secured FDA approval for new reactor (LVR-10) and LEU Mo-99  1 st commercial sale of NTP LEU Mo-99 (Dec. 2010)  1 st FDA approval ANSTO LEU Mo-99 processes (June 09, Apr. 11’)  regular commercial shipments from NTP and ANSTO (May-June 2011 and ongoing)  Active engagement with Mo-99 projects  Advocacy to restore separate reimbursement for diagnostic RPs in hospital outpatient

13. Impact of reactor outages (2009-10), medical reimbursement pressures, and medical radiation concerns have decreased demand for Tc-99m How will future demand evolve? The Mo-99 production landscape is changing - many new projects, including domestic U.S., on drawing board How many will succeed? When? 2016-2018 situation unclear (post-NRU) LEU-based production will be the future of Mo-99 supply Medicare reimbursement landscape is changing with payments decreased and/or “bundled” with procedures Need for separate Medicare payment for dRPs to compensate for Mo-99/Tc-99m cost increases Lantheus has taken a leadership role in securing future Mo-99 supply Toward a More Secure Future?
