Cath question

The physician did a CPT® 93458-26/59 and 92982, and while in the recovery area the patient had a recurrence of a massive ST elevation of the inferior leads and had to be brought back to the cath lab. Physician also billing for CPT® 93454, 92980,92973 (for the return back to cath lab) however since 93454 is bundle with 93458 would it be appropriate to use modifier 78 on the 93454?

Thank you for your time.
