With CMS 2025 updates, emergency medicine billing is evolving with stricter E/M coding guidelines, reimbursement shifts, and new audit risks. Emergency departments (EDs) must navigate increased scrutiny on medical necessity, modifier usage, and facility coding.
At Medical Billers and Coders (MBC), we specialize in Emergency Medicine Billing Services, ensuring fast reimbursements, compliance with payer policies, and reduced claim denials.
Key CMS 2025 Updates for Emergency Medicine Billing
-
Revised Evaluation & Management (E/M) Coding Guidelines
- E/M level selection now focuses on Medical Decision Making (MDM) and time spent on patient care.
- Time-based billing requires clear documentation of critical care duration.
- CMS emphasizes clarity in history and physical exam documentation.
MBC Solution: We ensure accurate E/M coding and thorough documentation to prevent downcoding and underpayments.
-
Increased Scrutiny on Modifier 25 & 59
- Modifier 25 (E/M service with a procedure) must have distinct documentation.
- Modifier 59 (separate service) is a top audit target.
MBC ensures proper modifier usage to avoid audits and claim denials.
-
Critical Care Billing Updates (99291 & 99292)
- CMS clarified that 99291 (first 30-74 minutes) requires detailed documentation.
- Additional 99292 units require precise time tracking.
MBC Strategy: Our team reviews time-based documentation to prevent reimbursement cuts.
-
Telehealth Expansion for Emergency Medicine
- CMS continues covering select telehealth services for ED providers.
- ED telehealth visits (CPT 99281-99285) require real-time audio-video communication.
MBC ensures proper billing for tele-emergency services.
Key Components of Emergency Medicine Billing

Proper Use of E/M Codes for Emergency Visits
ED visits are categorized based on complexity and MDM levels:
- ServiceCPT CodeMDM Complexity

- Level 2 ED Visit 99282 Low
- Level 3 ED Visit 99283 Moderate
- Level 4 ED Visit 99284 High

MBC ensures proper code selection to maximize reimbursements.
-
Facility Fee vs. Professional Fee Billing
Emergency medicine billing involves:
- Facility fees (charged by the hospital for ED resources)
- Professional fees (charged by physicians for services rendered)
MBC ensures accurate billing for both components.
-
Bundled Services & Modifier Usage
- Laceration repairs, fracture care, and procedural sedation are bundled unless modifiers justify separate billing.
- Common ED modifiers include:
-
- Modifier 25 – Separates an E/M visit from a procedure
- Modifier 57 – Decision for surgery in ED
- Modifier 59 – Distinct procedural service
MBC prevents modifier misuse to reduce audit risks.
