Coding
Modifier 25
Appended to an E/M code to show a significant, separately identifiable evaluation and management service was performed on the same day as a procedure.
What it means in dermatology
In dermatology, modifier 25 usually appears when a patient presents for a scheduled lesion check and a new, unrelated complaint is evaluated and documented in the same visit. The E/M work has to stand on its own: a separate history, examination and medical decision-making that would justify the visit even if the procedure had not happened.
It is one of the most audited modifiers in the specialty. Payers run frequency analytics at the provider level, and a practice appending it to a large share of same-day procedure visits will draw a review whether or not each instance was defensible.
Why it matters to your revenue
Used correctly it protects legitimate revenue that would otherwise be bundled; used reflexively it invites a payer audit with extrapolated recoupment.
