ED Coding and Reimbursement Alert

Question: I am having trouble deciding between E/M levels for this encounter: The notes clearly indicate that the ED physician performs comprehensive examination and high-complexity medical decision making for a patient with a possible myocardial infarction (MI) who had suffered an MI five years earlier; the physician's final diagnosis is Dressler's syndrome. I am not sure if the history level is comprehensive or detailed. The physician addressed five history of present illness (HPI) elements and reviewed 10 systems (ROS). Is this a level-five E/M?

Answer: You'll have to review the notes to determine the level of past, family, and social history (PFSH) before deciding on an E/M code.

This encounter involved extended HPI and a complete ROS, both requirements for a comprehensive ED E/M. A comprehensive history also requires a complete PFSH,which you do not mention in your description.

During a complete PFSH, the physician asks the patient direct questions about at least two of the three PFSH elements.

If she only asks about one PFSH elements, it is a pertinent PFSH.

Best bet: Count the PFSH elements that the physician documented. If she performed a complete PFSH, report 99285 (Office or other outpatient visit for the evaluation and management of a new patient, which requires these 3 key components: a comprehensive history; a comprehensive examination; medical decision making of high complexity ...) for this encounter with ICD-9 code 411.0 (Postmyocardial infarction syndrome) appended to represent the patient's condition. You may need to hunt for the PFSH within the body of the HPI or ROS because the information may not be separately marked.

If you cannot find evidence of any PFSH for this patient, this will only qualify as an expanded problem focused history, so you should select 99283 (... an expanded problem focused history; an expanded problem focused physical examination; medical decision making of moderate complexity ... ) with 411.0 instead.
