Can someone help me or guide me to the best resource for injection coding?? I'm confused on which injections allow for an admin and which do not.

I am also searching for the fee schedule for injections which I cannot find on the regular Medicare fee schedule by local...

ie. J3130 / J9217 / J9202 / J3315 /

Any info on injections and what should/can be billed with them would be most helpful.

Thank you!
