If printing on the form they are spaced out
If sending electronically we separate them out internally.
Each modifier is two letters so we separate them internally.
e.g. E1E2E3E4 will print or transmitted as E1 E2 E3 E4
Each claim line has it own set of modifiers.
Hope that helps
another idea that came to mind is when billing punctal plugs you have E1 E2 E3 or E4 on the first line but one of these with 51 on the 2nd, 3rd and 4th line of the claim
This question is for MVE Forum....
with only 4 spaces we may be denied as you listed 55RT is an invalid number
55 is OK
RT is OK
55RT would likely be denied
can you check into this?
if your assumption is correct, all is well and no action is needed
if not, My Vison Express has no way of billing services where multiple modifiers are necessary
would we need 55,RT? or 55 RT? perhaps the MVE contact within GatewayEDI can clarify?
