Wiki Can modifier58 & 79 be billed on the same code?

[aruffolo]

I have a situation where a patient is receiving an intravitreal injection during the post op periods of the following procedures:

• an unrelated cataract surgery
• an unrelated retinal detachment surgery (performed on a different eye)
• a related PRP laser treatment

Technically, this injection could be considered both related and unrelated. Would it even be proper to code both 58 & 79?

Thanks!
