This information is right in the Evaluation and Management section of CPT, and there is more info in the guidelines.
To answer the question, it depends on if the patient is new or established:
-A new office patient requires 3/3 key components to be met or exceeded, so therefore in your example the 'weakest link' is the expanded problem focused history which limits you to a level 2 new patient office visit, 99202
-An established office patient requires 2/3 key components to be met or exceeded, so therefore in your example you can drop the lowest score, you meet the requirements for a level 4 established office patient visit, 99214 (comprehensive exam, moderate medical decision making.)
