Hello everyone and happy Thanksgiving !!!

I need help coding this:

Ptn present in office to discuss abnormal Pelvic Sono Report. The report says: "fibroids and etc" ABNORMAL. Ptn came in to the office for discussion results. She spends 15-20 mins face to face w/ dr., they decide to repeat sono in 6 months for comparison. she had her vitals done and then leaves w/ no exam. Can I bill 99213 with 218.9??? or is there a diff CPT code to be used since no exam was done???

Thanks for your help in advance!!!!
