Injections and modifiers

I'm currently receiving a rejection for my billing with BCBS. We've entered 20550 and 20600 as services for the visit. our billing service is saying that they're only allowing 20600 and want to add a modifier to 20550 to get this paid. I'm unaware of what modifier we should use. any suggestions?

re: Injections and modifiers

The most common modifiers for 20550 as per Medicare are listed below. Make sure that whichever modifier you choose is applicable and is supported by the documentation. If none of these are applicable you should check the NCCI edits, or look up the codes on Find-A-Code to see more modifiers. If you don't have a Find-A-Code account you can create a free trial and view the information, even do a check on the NCCI edits there. When I looked it up it indicated that 20600 would be the only one paid without an applicable modifier, though BCBS could have their own policies regarding the payment and which modifiers are applicable. You may also want to check their policies, and can do so with a free trial at Find-A-Code.
