How to code E&M and small joint injections for multiple fingers

Our Orthopedic who comes monthly to our clinic treated a new patient for multiple isses and I am unsure how to bill for them. He did a new patient E&M and then four small joint injections (20600) with 80mg of Depomedrol. One injection in left thumb, one in rt thumb, one in rt index finger and one in rt long finger. He want's me to bill the 20600 joint injection four times as well as the office level. would it be:

99204 w/mod 25 DX 724.5, 729.5
20600 w/mod F5,F6,F7 DX 727.03 (OTY 1) or QTY (3) ???
20600 w/mod 59,FA (QTY 1)
J1030(40mg) w/mod RT,LT DX 727.03 (QTY 2)

So afraid of overcharging or triggering a denial.
