FB removal includes an incision, not just picking out debris with tweezers. Wound care guidelines are very specific, so it doesn't matter if your nurse is a wound care expert, it matters what she actually did. Those wound care codes include selective excisional debridement down to deeper levels of skin and subcutaneous tissue, muscle and/or bone, so what you are describing is not wound care for the purposes of the codes in the integumentary and medicine sections of CPT.
Basically, (without seeing the note), I'd simply bill an E&M visit, unless you're bumping up any other 10-day global procedures that you haven't mentioned.
