Can I bill a 99212 if my midlevel is seeing the patient and performing a review of systems and a focused based exam? She also administers the injection herself. I was taught you can not bill an E/M code if the patient is scheduled for a weekly injection based on CMS rule from 2004. Our patients are expected to return every 7-10 days. My midlevel states since she is doing the work, therefore, she should be paid for what she does. So she wants me to bill 99212-25, 96372 and J1071, who is correct? Can someone help me with this issue?
