I am a new aapc member....with my first question (hope I'm doing this right)

Podiatry billing is new to our practice, so we're learning. Medicare denied a couple claims due to missing modifier and we can't figure out what they want.
They are the removing of hyperkeratotic lesion codes (11055 & 11056) in these 2 examples. Both were billed with diagnosis codes 701.1 (hyperkeratosis) and 729.5 for pain.
Medicare class findings/Q codes do not apply to either of these patients.

Anyone know what we're missing?
