Emergency Medicine Billing Services
Emergency medicine billing is unforgiving because the visit level is decided by the documentation, and the documentation is written under pressure. Emergency department visits are billed with codes 99281 through 99285, and since 2023 the level is driven primarily by medical decision making or total time, not by counting history and exam elements. A chart that shows the work but does not state it in the terms payers read will underpay, and a high-level code without matching complexity will draw audits.
MedPlus RCM provides medical billing, coding, credentialing, and denial management for emergency medicine practices, built around the documentation and coding rules that actually decide whether ED claims pay.
Emergency medicine billing challenges
Medical decision making is the primary driver of the ED visit level. It rests on three elements: the number and complexity of problems addressed, the amount and complexity of data reviewed, and the risk of the patient’s condition or management. Documenting differential diagnoses considered, independent review of labs and imaging, discussions with consultants, and the risk assessment is what supports a higher level. Under-coding a genuinely complex visit loses revenue on every shift, while over-coding without that support is one of the most common audit triggers in emergency medicine, alongside frequent critical care coding and unusual procedure combinations.
Critical care coding is a second, separate discipline. Critical care codes 99291 and 99292 apply only when the patient has a critical illness or injury and the physician provides at least 30 minutes of critical care on that date, with the time documented. If critical care lasted less than 30 minutes, the visit must be billed with an ED code instead, even for a critically ill patient. Procedures performed during the ED visit, such as CPR, are reported separately, with modifier 25 on the evaluation code when the procedure and the evaluation are significant and separately identifiable services.
A third pressure point is payer mix. ED groups see every payer at once, including out-of-network and uninsured patients, and each payer applies its own authorization and bundling rules to the same visit. Coding must hold up across all of them, and denials must be worked fast, because timely filing windows close while the group is still seeing patients.

Frequently asked questions
What decides the level of an ED visit code?
Medical decision making or total time. The chart must show the complexity of the problems, the data reviewed, and the risk involved, since history and exam element counts no longer drive the level.
When can we bill critical care instead of an ED visit code?
When the patient is critically ill or injured and the physician provides at least 30 minutes of critical care on that date, with the time documented. Less than 30 minutes means an ED code, not critical care.
Why do high-level ED visits get audited?
A high percentage of level 4 and 5 visits, frequent critical care codes, or documentation that does not match the level billed are common audit triggers. The note must support the code.
Do you handle out-of-network and uninsured ED claims?
Yes. We bill every payer class on the same workflow and work denials and patient balances to the applicable timely filing and appeal rules.
How long does it take to switch our billing to MedPlus RCM?
Onboarding takes between 2 and 4 weeks depending on practice size, including data migration and payer clearinghouse setup.
