Well, it's not up to the coders to say what 'seems pretty steep' or not. We don't make the rules, we just apply them. ☺
In any case, it really isn't a big change. A visit for a patient with worsening acne with prescription drug management could likely involve a detailed history and/or exam, which could be coded as 99214 under the current rules too. I'd note too that Appendix C of CPT includes visits for treatment of acne in clinical examples for both 99213 and 99214 visits:
99213:
Office visit for a 13-year-old, established patient, with comedopapular acne of the face which has shown poor response to topical medication. Discussion of use of systemic medication.
99214:
Follow-up visit for a 15-year-old withdrawn patient with four-year history of papulocystic acne of the face, chest, and back with early scarring and poor response to past treatment. Discussion of use of systemic medication.
