Can anything be coded when a patient is seen by dentist only to ask questions?

Hi all, my office keeps running into situations where patients will come in to see a dentist but no exam is performed. The patient will come in solely to ask questions about their situation or go over a treatment plan with the dentist with different family members. The office admin would like these visits billed out but I don’t see an appropriate code. Maybe D9430? Would really appreciate any input on this, or what other offices do in this case. Thanks!
