Structures ED visit documentation with chief complaint, MDM, and disposition rationale. Use when charting emergency visits, documenting medical decision-making, or creating ED notes.
Structures emergency department visit documentation with chief complaint, history, examination, medical decision-making (MDM), and disposition rationale per 2021 E/M coding guidelines.
Emergency department documentation serves three simultaneous purposes: clinical communication, medicolegal protection, and billing compliance. ED physicians face malpractice claims at rates 3-4 times higher than most specialties, and the medical record is the primary defense document. Under the 2021 CMS Evaluation and Management (E/M) guidelines, ED visit coding (99281-99285) is now driven by medical decision-making (MDM) complexity rather than documentation volume, but the record must still support the billed level of service.
Incomplete documentation is the leading cause of ED coding downgrades, costing the average emergency group $50,000-$150,000 annually in lost revenue. Beyond billing, inadequate documentation contributes to communication failures — the Joint Commission identifies handoff communication breakdowns as a root cause in over 60% of sentinel events. This skill ensures ED notes are clinically accurate, legally defensible, and compliant with CMS documentation requirements.
Document in the patient's own words using quotation marks. Keep to one sentence.
Use the OLDCARTS mnemonic for symptom characterization:
| Element | Content | Example |
|---|---|---|
| Onset | When and how the symptom began | "Sudden onset 2 hours ago while watching TV" |
| Location | Anatomic location and radiation | "Substernal, radiating to left arm" |
| Duration | How long the symptom has lasted | "Constant for 2 hours, not relieved by rest" |
| Character | Quality of the symptom | "Pressure-like, heavy sensation" |
| Aggravating | What makes it worse | "Worse with exertion, deep breathing" |
| Relieving | What makes it better | "Partially relieved by sitting forward" |
| Timing | Pattern, frequency, progression | "First episode, progressively worsening" |
| Severity | Quantified on appropriate scale | "8/10 on numeric rating scale" |
Document pertinent positives AND negatives relevant to the differential diagnosis.
Under 2021 E/M guidelines, the exam does not determine code level, but documentation must support the clinical decision-making.

High-risk documentation practices for examination:
MDM is now the primary driver of ED E/M code level. Three components are assessed; the code level is determined by the highest level where at least two of three components are met.
| Level | Problems | Examples |
|---|---|---|
| Straightforward (99281-82) | 1 self-limited or minor problem | URI, simple laceration, minor sprain |
| Low (99283) | 2+ self-limited problems OR 1 acute uncomplicated illness | UTI, ankle fracture, simple cellulitis |
| Moderate (99284) | 1 acute illness with systemic symptoms OR acute complicated injury | Pneumonia, kidney stone with vomiting, fracture requiring reduction |
| High (99285) | 1 acute illness posing threat to life or function | ACS, stroke, sepsis, pulmonary embolism, acute surgical abdomen |
| Level | Data Requirements |
|---|---|
| Straightforward | Minimal or no data |
| Low | Order or review lab/imaging OR review prior records/history |
| Moderate | Order AND review tests OR independent interpretation of imaging OR discussion with external physician |
| High | Independent interpretation of tests + discussion with external physician or multidisciplinary team |
| Level | Risk |
|---|---|
| Straightforward | Minimal risk of morbidity |
| Low | Low risk (OTC drugs, minor surgery, PT) |
| Moderate | Prescription drug management, decision for minor surgery, IV fluids |
| High | Drug therapy requiring intensive monitoring, decision for major surgery, decision not to resuscitate |
Document each component explicitly in the MDM section:
MDM: This [age] [sex] presents with [chief complaint]. The differential includes [list].
Data reviewed: [labs, imaging, prior records, outside physician discussion].
Assessment: [working diagnosis with supporting evidence].
Risk: [specific risk factors — e.g., "acute MI cannot be excluded, risk of death"].
Plan: [treatment, disposition, follow-up].
| Disposition | Required Documentation |
|---|---|
| Discharge | Diagnosis, condition at discharge, medications prescribed, follow-up instructions, return precautions, patient understanding confirmed |
| Admission | Admitting diagnosis, attending physician name, bed assignment, pending results, handoff communication |
| Transfer | EMTALA compliance documentation, accepting physician/facility, reason for transfer, risks/benefits discussed, patient consent |
| AMA | Capacity assessment, risks explained, understanding documented, follow-up offered, AMA form signed |
| Death | Time of death, pronouncement, family notification, medical examiner notification criteria, organ donation screening |
