Routine Footcare

“I have a patient who honestly only has three mycotic/dystrophic toenails. This elderly gentleman, with Medicare, returns to the office every 90 days for routine foot care (RFC). According to Medicare guidelines, he does qualify for RFC with his physical examine findings. My question is can I bill CPT 11720 for the debridement of the three dystrophic nails and then CPT 11719 for the trimming of the other seven non-dystrophic toenails?”
