I am having trouble finding documentation on how to bill addendums to a pathology report if the addendum is signed by a different pathologist than the pathologist that signed the initial final report.
For example:
Dr. A signed final interpretation and report for an FNA
Dr. B signed addendum documenting the immediate assessment of that FNA. (no change to diagnosis)
Typically we bill the two codes (88172 & 88173) together on the same claim. Do we bill it with Dr. A who signed the final report or Dr. B who signed the addendum?
Another example:
Dr. A signed final report of gastric biopsy
Dr. B signed addendum documenting special stains performed on the gastric biopsy changing the diagnosis.
Again, we typically bill the codes together on the same claim. Do we bill it with Dr. A who signed the final report or Dr. B who signed the addendum changing the diagnosis? Or if the diagnosis was not changed by the special stains in the addendum which Dr. would we bill for?
Thank you in advance.
