Background
- Understanding ED billing is essential for appropriate reimbursement and documentation
- As of 2023, CMS E/M coding for ED visits is based primarily on medical decision making (MDM) or total time, no longer requiring specific HPI/ROS/exam element counts for billing level[1]
- ED E/M visits use CPT codes 99281-99285; critical care uses 99291-99292
- Proper documentation directly impacts revenue and medicolegal protection
ED E/M Billing Levels
| CPT Code | Level | MDM Complexity | RVUs |
|---|---|---|---|
| 99281 | Level 1 | Straightforward | 0.64 |
| 99282 | Level 2 | Low | 1.24 |
| 99283 | Level 3 | Moderate | 2.10 |
| 99284 | Level 4 | Moderate | 3.57 |
| 99285 | Level 5 | High | 5.16 |
| 99291 | Critical Care (1st hr) | N/A | 8.19 |
Medical Decision Making (MDM)
- MDM is the primary driver of ED billing level under current CMS guidelines
- MDM complexity is determined by three elements:
- Number and complexity of problems addressed
- Amount and complexity of data reviewed and analyzed (labs, imaging, records, discussions)
- Risk of complications, morbidity, or mortality from the patient's condition or management
How to Support Higher MDM
- Document differential diagnoses considered (see Differential diagnosis documentation)
- Document independent review of labs and imaging
- Note discussions with consultants and other providers
- Document review of external records
- Note prescription medications ordered
- Document the risk assessment including potential complications
- See MDM for different chief complaints for sample MDM documentation by chief complaint
Legacy CMS Requirements (Historical)
Note: These element counts are no longer required for billing level under 2023 guidelines, but remain part of the medical record structure
History of Present Illness (HPI)
- Location, Severity, Timing, Modifying factors, Associated signs and symptoms, Onset, Quality, Duration
Past Medical, Family, Social History
- Past medical/surgical history, Hospitalizations, Immunizations
- Family history (health status, deaths, hereditary diseases)
- Social history (drug/alcohol/tobacco use, employment, marital status)
Review of Systems
- See Review of systems documentation
- 14 organ systems recognized by CMS[2]
Physical Exam
- See Physical exam documentation
- 14 systems recognized by CMS[2]
Critical Care Billing
- See Critical care documentation for detailed information
- Critical care can be coded when total duration of critical care services ≥30 minutes
- Time does not need to be continuous
- Must exclude separately billable procedures from critical care time
- Can bill E/M plus critical care if the E/M is for the initial evaluation before the patient becomes critical
