Patient came into the ER and had I&D performed (10080). Patient came back to ER two days later as the abscess was getting worse and second I&D (10080) was performed. The insurance is now denying the second 10080 as bundling and I know this CPT has 10 day global period. The second E&M visit was paid, but can we be billing the second 10080 due to the global period?

Thanks!
