Wiki Revision of a reverse TSA

If the provider only revises the Glenoid and Humeral tray do you bill the revision code both components with a 52 mod ?
If the provider revises both the Glenoid and Humeral components, you use CPT 23474. No Mod. If only one of the components is revised (glenoid or humeral), you use 23473, again no mod. I hope this helps! :)
