I really need some help with this - I have tried many things...
My doc is doing the post surgery follow-up visit after cataract surgery. I am billing:
1st Surgery date - 66984 RT 55 as 1 unit with notes: Assumed Care date and Relinquished care date is 90 days from surgery date
2nd surgery date - 66984 LT 55 - 1 unit with a different Assumed Care date and Relinquished care date 90 days from this surgery date...
Follow-up Date - 99213 - I've tried 24, 25, 79 - all denied modifiers...
I can't get the 99213 code paid at all - I know I have the modifier wrong, but I'm clueless as to which one is correct. I was using the assumed care date that our office saw the patient and the relinquished date was when the surgeon released the patient to us, but medicare just told me that was wrong. the relinquished date should be 90 days post-op. I've used "1" for units and was being paid, but last medicare customer service rep said I should be using "90" for 90 days...
Help!
