Core Clinical Executive Summary
Evaluation and Management (E/M) coding underwent a historic modernization eliminating the cumbersome 1995/1997 physical exam and history bullet-counting rules. Under the current American Medical Association (AMA) and CMS framework, outpatient visit code selection is determined exclusively by: 1) The level of Medical Decision Making (MDM) as defined by each of three categories: Number and Complexity of Problems Addressed, Amount and Complexity of Data to be Reviewed and Analyzed, and Risk of Complications and Morbidity or Mortality of Patient Management; or 2) Total clinician encounter time on the date of the encounter, encompassing both face-to-face and non-face-to-face clinical tasks.
1. The 2026 Evaluation and Management (E/M) Regulatory Modernization
Under historical 1995 and 1997 guidelines, Evaluation and Management code selection depended on arbitrary bullet-counting across history of present illness (HPI), review of systems (ROS), and multi-organ physical examinations. Current AMA and CMS standards eliminate bullet-counting for all outpatient and inpatient services.
Level of service is determined strictly by one of two documented methods:
Method 1: Medical Decision Making (MDM)
Scored on the clinical complexity of the patient presentation across three distinct elements: Problem complexity, Data analyzed, and Risk of complications.
Method 2: Total Physician Time
Scored on the total non-duplicated face-to-face and non-face-to-face clinical time spent by the physician on the exact calendar date of the encounter.
2. The 3-Element Medical Decision Making (MDM) Grid
To qualify for a given level of MDM (Straightforward, Low, Moderate, or High), the documented encounter must meet or exceed 2 out of the 3 elements:
| MDM Level | Element 1: Problems Addressed | Element 2: Data Reviewed | Element 3: Risk of Complications |
|---|---|---|---|
| Straightforward (99202/99212) | 1 self-limited or minor problem | Minimal or none | Minimal risk (rest, ice, OTC meds) |
| Low (99203/99213) | 2 minor problems OR 1 stable chronic illness | Review prior external notes or tests (Category 1) | Low risk (physical therapy, minor surgery without risk) |
| Moderate (99204/99214) | 1 chronic illness with exacerbation OR 2 stable chronic illnesses OR 1 acute illness with systemic symptoms | Order/review 3 tests OR independent test interpretation OR discussion with external provider | Prescription drug management OR decision for minor surgery with identified risk |
| High (99205/99215) | 1 severe chronic illness exacerbation OR acute illness threatening life or bodily function | Comprehensive data satisfying 2 out of 3 data categories | Emergency hospitalization OR parenteral controlled substances OR elective major surgery with risk |
3. Total Time Thresholds for Office Encounters
When coding by time, the physician must document the exact total minutes spent. Clinical staff time cannot be counted toward the physician threshold:
New Patient (99202-99205)
- 99202: 15-29 minutes
- 99203: 30-44 minutes
- 99204: 45-59 minutes
- 99205: 60-74 minutes
- +99417: Each additional 15 minutes
Established Patient (99212-99215)
- 99211: Clinical staff (no physician required)
- 99212: 10-19 minutes
- 99213: 20-29 minutes
- 99214: 30-39 minutes
- 99215: 40-54 minutes
- +99417: Each additional 15 minutes
Clinical Audit Defense & Verification Protocol
1. Pre-Submission Review
Verify that the primary ICD-10 diagnosis code precisely matches the documented clinical indication and satisfies published LCD/NCD coverage policies.
2. NCCI Edit Verification
Cross-reference all concurrent procedure codes in our free NCCI Edit Checker to identify unbundling conflicts and modifier indicator flags.
3. Physician Authentication
Ensure the treating clinician personally reviewed, signed, and timestamped the EHR clinical note prior to claim submission to establish legal authenticity.
