I'm having a debate in regards to E&M billing for established pt's. If a pt is seen & the HPI is documented by someone other than the MD (MA/Tech) it's not being used which I understand. The exam & MDM meet level 99214. My reviewer is stating we can't bill an E&M at all due to the HPI & changing the code to 92012 in most cases. In established visits you need 2/3 which we have. Am I understanding that if the HPI is documented by someone other than the MD we can't use E&M at all ?
