E/M with procedure

Following scenario: A referral to perform an injection (ESI/TFESI/SIJ etc). from surgeon or external provider was created and the injection was approved/verification of benefits was completed. Patient comes to your office on a separate day for the procedure, can you bill E/M code with modifier 25 on day of procedure along with the procedure code? You are a different speciality (pain/anesthesia) from the surgeon or other referring provider.
