billing 0200T & 0201T

I have billed both of these codes and Medicare has denied as "Procedure/treatment is deemed experimental/investigational by the payer" Claims were appealed with documentation (Op Note and documentation where they have approved these procedures as of July 2009).
The DX codes being billed are 805.6 & 724.6. Any suggestions on a second level appeal to get these paid.
