Would need the op note
For an accurate response to surgical coding questions, please post the scrubbed op note.
Here's the lay description from Encoder Pro
67900
Repair of brow ptosis (supraciliary, mid-forehead or coronal approach)
Ptosis refers to a droop or displacement resulting from paralysis. The physician makes an incision directly above the brow (supraciliary), through the mid-forehead or near the hairline (coronal). A dissection is carried down to the area of the brow. The skin is pulled superiorly and the brow approximated to its proper position above the supraorbital rim. The incision is repaired with sutures.
If what your surgeon did is more extensive than this, then you might want to use the 22 modifier to show additional difficulty.
If it's more involving the bony structures, and not just skin and muscle, I don't think this code will work.
You might try posting your question (with the op note) in the Plastic Surgery thread - more likely to get coders with this kind of expertise to help you there.
Hope that helps.
