I was wondering how people are billing 92601-92604 for unilateral and bilateral situations and if they are getting denials or payments. I have read to use modifier 50, RT & LT, or 22 to indicate bilateral, but our coding program says that these CPT codes do not allow any of those modifiers and that 92601-92604 is representative of a bilateral procedure and to add modifier 52 if performed unilaterally. Any insight on this issue would be greatly appreciated! Thank you!!!
