Hello, this is my first time using the forum, so I wasn’t sure how to make a post/thread. Hopefully someone can help me out or point me in the right direction. I bill for an Internal Med office and the doc says there is a modifier to use when a patient is seen in the office and then later transported to the hospital. I have one now that was seen for new pt visit but half way through, the ambulance was called and transported the pt to hospital. The doc wants me to bill 99204-AI-25 with 99354, can anyone provide any insight, please?
