What’s the one thing that trips up dermatology billing more than anything else? Modifiers, honestly. A single visit might involve several biopsies or destructions, and each one needs its own modifier to avoid getting bundled and underpaid. Miss just one, and the shortfall often doesn’t get noticed for months, because it’s not a denial it’s just a smaller check than it should’ve been. Billing for dermatology needs someone checking modifiers at the procedure level, every time, not just glancing at the visit as a whole and moving on.
