This is the lowest level of care for established patients in the office. Internists used this code for only 1.72% of these encounters in 2019. This E/M code is unique in that it is the only one which does NOT REQUIRE THE PRESENCE OF THE PHYSICIAN. There are no specific documentation requirements, but the purpose of the visit should be recorded. The Medicare allowable reimbursement for this level of care is $23.46 and it is worth 0.18 work RVUs.
