Wiki Medicare ASC Modifier

[coder80]

Can someone please tell me which modifier to use on the ASC claim to Medicare.
When NO modifier is added, the claim reject B20 for already rendered by other provider?
is the Modifier 76 77 79
Thank you!

Those modifiers are for professional services, not for facility. What service was denied and why are you thinking that this should be coded as a repeat service? Did the patient has a surgery at your facility and was transferred somewhere else on the same day and have that procedure again? You may need to contact your Medicare and get additional information as to why this was denied.
