In looking at the CMS NCCI Mutually Exclusive edits, it appears that 76815 is mutually exclusive, or not allowed, when billed w/ 76816 (or 76816 is Column I & 76815 is Column II). However, a modifier is allowed.

Under what cirucumstances would this be appropriate to bill the 2 codes together? Can you give a clinical example?

It seems to me that 76816 is a more thorough exam that should encompass whatever else would be inculded in the 76815.
