My OB/GYN doctor attempted to perform a tubal on a patient and couldnt finish a procedure due to an unforseen problem. She did, however, perform a D&C, hysteroscopy, and NovaSure ablation. The billers coded it as 58670 (Laparoscopy w/fulguration of oviduct) and used modifier 53. Medicare isnt paying for it with these codes. Any help on what to code to help collect payment?
