If you look in the cpt book under code 23350, underneath it it states "When fluroscopic guided injection is performed for enhanced mr arthrography, use 23350, 77002 and 73222. When they do the injection, do they just say the patient was injected with contrast and then transfered to mri? If so, code this with the above codes. Or does the rad talk about what he saw after the injection of the shoulder(diagnostic info) and then they transfer to mri? If so in this case, I would use 73040, 23350 and 73222.
Most of the times when they state that they did an "arthrogram" and then they send them for a mri, they really aren't doing an "arthrogram" but are just injecting the joint with contrast for the mri. It depends which scenario you have but most of the time you will be using the very first set of codes mentioned above (keep in mind if they do it under ultrasound guidance or ct guidance the 77002 will change to reflect which one it is).
