billing in ASC
trial stimulators Medicare 63650 x 2, second line needs a 76 modifier, each line is paid at 100%, for stimulators there is not a 50% write off for second line.
Commercial 63650 x 2, C1778 for lead implant
perm stimulators Medicare 63685, 63650 x 2 with a 76 modifier on second code and again each line is paid at 100%
Commercial 63685, 63650 x 2, C1822 for HF generator, C1820 for non HF generator, C1778 for leads.
Also check LCD's for these codes.
Medicare will request records for these procedures, so make sure you have MRI's and a Psych evalution along with notes showing the % of relief from the trial.
Hope this helps.
