In late 2009, eye doctors successfully lobbied to overturn a new Medicare directive that reduced reimbursements for Avastin from $50 to $7 per injection.Medicare's action temporarily forced eye doctors to use Lucentis instead of Avastin.he editorial noted that Lucentis costs more than $2,000 per treatment, while Avastin costs less than $150 per treatment.
