Chest mass excision with out rib removal

Hello ~

I am in need of some advice.

The Surgeon did a Chest wall Mass removal. He dissected down to the ribs took tissue sample also along with mass; No ribs were removed so can not use 19260.

He could see into chest cavity and everything looked good.

I coded 21555 but just does not seem to be extensive enough?

Is there another code out there that could be a better fit?

Any suggestions would be appreciated~ Thanks!
