If the dr performed a removal of cataract with insertion of lens but had to take the lens out to do a core vitrectomy and didn’t put the lens back in. How would that be billed? Would I bill the 66984 with a modifier or only bill for the vitrectomy. There is also the option of 66850 with the vitrectomy code. I do not do many of these types of surgeries and I am stumped on this one. Could anyone help me out please?
