Maybe another physicain is already billing those codes?
For instance maybe the tech who performed the 99306 forgot to put the TC modifier on that procedure and was paid for the whole thing so they are denying your provider.
Was this patient admitted to OBS under your physician? If not you would use the appropriate outpatient/office (99201-99205 or 99211-99215) range visit level code for the services provided with an outpatient place of service and the -25 modifier. That could possibly be the problem.
A while back the hospital our doctor's do some work at had hospitalist claiming the OBS admits and regular admits that our doctor's were actually performing (and some of their procedures as well that maybe they had assisted with but not performed on their own. Our docs had performed them) and we had to call their billing department and have it straightened out. Of course we sent notes to the insurance company first showing that our doc was the admitting/operating physician as well.
The one denial you listed looks as if it is the denial for 99306-26. What was the actual denial for 99219-25?
