What 99284 covers
In a hospital emergency department, a physician or other qualified health care professional evaluates an acute illness with systemic symptoms, an acute complicated injury, or a chronic illness with exacerbation when the overall medical decision making (MDM) is moderate. Emergency physicians commonly furnish this care, but another physician or qualified professional evaluating the patient in the ED may report an ED visit. The code is the same whether the patient is new or established. A presenting complaint, tests ordered, or discharge alone cannot establish the level.
Select the level by MDM, not time: at least two of the three elements—problems, data, and risk—must meet moderate criteria. Document the problems addressed, qualifying data, treatment decisions such as prescription drug management, and disposition reasoning. Do not count a separately billed ECG interpretation as independent interpretation for MDM data. Report a significant, separately identifiable ED evaluation with modifier 25 when a minor procedure, such as simple laceration repair, is also billed. If the same physician provides ED care and initial inpatient or observation care that date, report the initial hospital care instead of a separate ED visit.

99284 billing questions
Can time be used to support 99284?
No. Emergency department visit levels are selected by medical decision making, so time spent does not determine the level.
What separates 99284 from 99285?
99284 requires moderate MDM; 99285 requires high MDM. At least two of the three MDM elements must support the selected level.
Does the ED visit need modifier 25 when a procedure is also performed?
Append modifier 25 to 99284 when the ED evaluation is significant and separately identifiable from the usual work of a minor procedure, such as a laceration repair. Report the procedure with its own code.
Can 99284 be billed if the same physician admits the patient to observation or inpatient status?
When the same physician provides ED evaluation and initial inpatient or observation care on the same date, include the ED work in the initial hospital care service rather than separately reporting 99284.
Does prescribing medication alone qualify for moderate risk?
Documented prescription drug management supports moderate risk, one of the three MDM elements. A second element—problems or data—must also meet moderate criteria for 99284.
Can a non-emergency physician report 99284?
Yes. A physician or qualified health care professional evaluating a patient in the emergency department may report an ED visit even if emergency medicine is not their specialty.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
