    Which level of evaluation and management (E/M) code should you use? There are two ways to determine this: One is physician-time based and the other is based on the level of medical decision-making (MDM) that is required. The MDM level is dependent on the 1) problems, 2) data, and 3) risk that the physician must contend with (see “E/M Rules for Office Visits: What Level of Medical-Decision Making?” Savvy Coder, June).

    Some clarifications. Although new E/M rules have been in force for eight months, practices are still getting to grips with the nuances of the new system. Here is a refresher on two of MDM’s components, including responses from the American Medical Association (AMA), which maintains the Current Procedural Terminology (CPT) codes, including the E/M codes.

    MDM’s Data Component

    The “amount and/or complexity of data to be reviewed and analyzed” helps to determine the MDM level.

    Q. What does analyzed mean?

    AMA’s response. “It is the process of using and anticipating using the test in the MDM process. If a test is ordered outside of an encounter, the ordering has not yet been part of the MDM level determination, so the results will be included in the subsequent E/M visit, if analyzed in the MDM of that encoun­ter. For a test that is recurring, and ordered once for multiple future dates, a new result may be used in determin­ing MDM level if it is analyzed in a subsequent encounter.”

    Q. If an ophthalmologist reviews a test by a referring source on one date and then reviews that same test at a subsequent encounter, can that second review count as a data item?

    A. No. Each unique test performed by the referring source can be counted only once.

    Q. If the ophthalmologist orders a computed tomography (CT) scan and blood work, do they both count?

    A. Yes. The CT scan would contrib­ute one data point and, depending on the individual CPT/HCPCS code(s), at least one more would be added for the blood work. With two data points, the exam would be considered to involve a “limited” level of data, which would help to support a “low complexity” level of MDM.

    Q. One way to meet the require­ments of a moderate level of data review would be to have a “discussion of management or test interpretation with external physician/QHP*/appro­priate source (not separately report­ed).” What does that mean?

    AMA’s response. “Discussion requires an interactive exchange. The exchange must be direct and not through inter­mediaries such as clinical staff. Sending chart notes or written exchanges that are within progress notes does not qualify as an interactive exchange. The discussion does not need to be on the date of the encounter but is counted only once and only when it is used in the decision making of the encounter. It may be asynchronous (i.e., does not need to be in person), but it must be initiated and completed within a short time period (e.g., within a day or two).”

    MDM’s Risk Component

    MDM’s risk component is defined as the “complications and/or morbidity or mortality of patient management.”

    Q. The AMA gives several examples of scenarios that would be considered moderate risk. These include the “de­cision regarding minor surgery with identified patient or procedure risk factors” and the “decision regarding elective major surgery without iden­tified risk factors.” Are these deter­mined by the global period of zero, 10, or 90 days of post-op care?

    AMA’s response. “An elective pro­cedure is typically planned in advance (e.g., scheduled for weeks later). An emergent procedure is typically per­formed immediately or with minimal delay. Both elective and emergent pro­cedures may be minor or major.” Note: For MDM purposes, the terms minor and major surgery are not determined by the global period.

    More on MDM’s Risk Component

    Q. Drug therapy requiring intensive monitoring for toxicity is listed under high risk. What qualifies?

    AMA’s response. “A drug that requires intensive monitoring is a therapeutic agent that has the potential to cause serious morbidity or death. The monitor­ing is performed for assessment of these adverse effects and not primarily for assessment of therapeutic efficacy.”

    General Questions

    Q. Rather than base your choice of E/M code on the level of MDM, you can base it on the total time that the physician spends providing the service on the date of the encounter. When determining that time duration, would you include gonioscopy or serial tonometry performed by the physician; travel to a satellite office; or provision of general eye care education that is not required for the management of a specific patient?

    A. None of these examples count. Gonioscopy and serial tonometry have their own CPT codes. If you used physician time spent on that testing to justify submitting a higher level of E/M code and you also billed separately for the testing using the test’s CPT code, that would be perceived as double dipping.

    Q. When will other places of service—such as hospital and emergency de­partments—adopt the same E/M requirements as office-based exams?

    A. January 2023. Until then, documentation in those facilities must meet the 1997 guidelines.
