I have a provider who did a brow lift - code 67900 - to correct a brow ptosis that was causing vision issues - he made one incision high on the forehead near the hairline. Because the procedure fixed a bilateral ptosis which was affecting the patients vision in both eyes, the provider feels he should be able to bill for a bilateral procedure. My issue is that he only made one incision and created only one flap and then closed only one incision. Thoughts ? suggestions ?
