I am also new to coding ophthalmology. I was wondering if you could answer a question for me or direct me to someone who can?
I have a provider that billed for a surgery in August that has a 90 day global period, and then he brings the patient back in September and performs CPT code 92134 with a different diagnosis code. Am I able to apply a modifier 58,78, or 79 to any of these types of tests when performed in a global period of a surgery? Or does it matter? I know that if another surgical procedure was done that I would be able to, but I'm unsure of what to do about a test.
Thanks for any and all help!
