A cancer patient who has had a relapse after moving states is an inpatient at the cancer floor of the local hospital. Her current oncologist has obtained her previous medical records from oncology, pulmonology, general surgery, transplant team, and cardiology and is spending a significant amount of time reviewing her previous care and how the cancer was treated by her previous doctors. He has spent an additional hour going over the charts from her previous providers and has spent time on the phone with her previous oncologist. This prolonged service did not involve face-to-face time with the patient but was necessary for review of her medical history and previous treatments and responses. What evaluation and management code should be used for this encounter?
