modifier 59
It really depends on who you are billing.
I have a cheat sheet for many different tidbits I am coding whether its anesthesia, pathology or labs.
Unsure which program you are using for coding, but we use Epic. Whenever I would come up on a problem especially consistent denials - I would have my go to tech person create an edit and drop that code into my work queue to take care of it's needs (adding description, adding modifier, changing it from billing x number of line items to billing it out as a quantity instead because THAT IS HOW THEY - the insurance company wants it billed).
