CPT: 99213, 89060
ICD-10: M10.072
Coding Rationale
This is an established outpatient visit. The encounter is coded as 99213 because it included:
- History—Expanded problem-focused history. The history of present illness was brief, the review of systems was extended and the past medical and social history was documented.
- Examination—Detailed. There were seven organ systems examined. This makes the exam level detailed.
- Medical Decision Making—Low complexity. The number of problems was limited (established problem worsening), amount of data was minimal (labs) and the level of risk was moderate for prescription drug management. This makes the MDM low complexity.
Rationale for level three E/M visit: because the history was expanded problem focused, the exam was detailed and the MDM was low complexity. An established patient visit only needs two out of the three elements (history, examination and medical decision making) to determine the level of a visit.
