I have a question, i hope someone can help me or point me in the right direction. I work in an OBGYN Clinic and i have a doctor who spent 60+ min with an established patient for depression. I want to know if i can charge more than a 99215, which is only 40 minutes. It seems like money lost. Is there another E/M add on code or code i can use with it? Any help greatly appreciated. She wants to charge for the 60 + minutes.
