How Thrive Supports Emergency Medicine
Emergency Room Billing That Understands the Pace of Emergency Care
We handle emergency room medical billing for hospital-based EDs, freestanding EDs, and outsourced emergency medicine groups. That means coding to medical decision making rather than a checklist, separating professional and facility claims correctly, and pushing back on payers when a claim gets downcoded without documentation to support it. We do not sell billing software or an EHR add-on. We are the team that codes, submits, and works your emergency department claims.
HIPAA Compliant
AAPC / AHIMA Certified Coders
Nationwide Coverage, All 50 States
Fewer avoidable rejections
MDM documentation review before submission reduces the share of Level 4 and 5 visits payers can challenge.
Faster Reimbursement
Clean first-pass submission on both professional and facility claims shortens the payment cycle.
Lower Days in AR
Aged emergency department claims get worked on a set follow-up cadence instead of sitting in a queue.
Defensible Documentation
Coding decisions are traceable back to the chart, which matters when a payer disputes a level.
Full Scope
End-to-End Emergency Department Revenue Cycle Management
Every task an ED’s revenue cycle depends on, handled in emergency medicine’s own terms rather than a generic billing checklist.
Registration & Eligibility Verification
ED-Specific Coding & Leveling
E/M leveling built on medical decision making, plus procedure, critical care, and trauma activation coding.
Dual Claim Submission
Professional (CMS-1500) and facility (UB-04) claims filed separately, on the rules each one follows.
Denial Management & Downcode Appeals
Denials and payer downcodes are traced to a specific cause and appealed with the supporting MDM documentation.
No Surprises Act Claim Compliance
Out-of-network claims are billed within qualifying payment amount rules, with open negotiation and IDR filings tracked to deadline.
AR Follow-Up
Aged and underpaid claims are worked until they resolve, not just resubmitted and forgotten.
Patient Statements & Collections
Patient-facing balances reflect correct cost-sharing under federal surprise billing protections.
Payment Posting & Reconciliation
Payments are posted and reconciled against contracted and QPA-based rates, so underpayments get caught.
Credentialing & Enrollment
Payer enrollment support for emergency physicians, APPs, and locum coverage joining your group.
Coding Reference
Emergency Room CPT Codes and HCPCS Reference
A working reference to the CPT and HCPCS code families that make up most emergency department billing and coding, useful for confirming what should be on a claim before it goes out.
- 99281–99285
ED Evaluation & Management
Five levels of ED visits, assigned by medical decision making rather than time. 99281 requires minimal or no physician presence, 99285 reflects high complexity decision making.
- 99291–99292
Critical Care
99291 covers the first 30 to 74 minutes of critical care in a calendar day, 99292 covers each additional 30 minutes. Cannot be billed alongside an ED E/M code for the same physician on the same date.
- G0390
Trauma Team Activation
Billed with revenue code 68x on the facility claim when a designated trauma team responds and pre-hospital notification criteria are met, alongside 30+ minutes of critical care.
- 99217–99226
Observation Care
Initial and subsequent observation codes used when a patient is held for evaluation rather than admitted, distinct from continued ED-level care.
- 99234–99236
Same-Day Admit & Discharge
Used when observation or inpatient admission and discharge both occur within the same calendar date.
- 12001–13160
Laceration Repair
Simple, intermediate, and complex wound repair, coded by anatomic site and total repaired length across wounds of the same complexity.
- 10060–10061
Incision & Drainage
Simple versus complicated or multiple abscess drainage, a frequent site of undercoding when multiple sites are treated.
- 25500–29086
Fracture Care & Splinting
Closed, open, and percutaneous fracture treatment, plus splint and cast application, distinguished from definitive orthopedic follow-up care.
- 99151–99153
Moderate Sedation
Reportable separately when a qualified independent observer monitors the patient during a procedure such as a fracture reduction.
- 93010 / 71046
EKG & Imaging Interpretation
Professional-component billing when the ED physician personally interprets an EKG or plain film rather than relying on a separate radiology read.
What Counts Toward Critical Care Time?
Only time spent at the bedside or immediately available on the unit managing a critically ill or injured patient counts. Time spent performing a separately billable procedure, such as intubation or central line placement, is excluded from the critical care time total.
Professional Claim vs. Facility Claim
The professional claim bills the emergency physician's evaluation and decision making on a CMS-1500 form. The facility claim bills the hospital's resources, staff, and space on a UB-04 form. Both are generated from the same encounter but coded, submitted, and adjudicated independently.
Where Revenue Gets Lost
=
The Denial Patterns Specific to Emergency Department Claims
Emergency department billing and coding fails in patterns that are different from scheduled outpatient care. These are the ones we see most often.
Payer Downcoding of Level 4 and 5 Visits
Some payers reclassify a 99285 or 99284 claim to a lower level based on the patient’s final diagnosis instead of the symptoms that brought them in, which runs against the federal Prudent Layperson Standard and is now subject to disclosure requirements under the No Surprises Act.
Critical Care Billed Alongside an ED E/M Code
When a patient deteriorates mid-visit and the same physician provides both an ED evaluation and critical care, CMS rules only allow the critical care code to be reported, not both. Missing this rule creates an automatic denial on one of the two claims.
Trauma Activation Documentation Gaps
G0390 requires documented pre-hospital notification and at least 30 minutes of critical care on the same date. Without both elements clearly in the record, the trauma activation charge is denied even when the response itself was appropriate.
Split and Shared Visit Modifier Errors
When both a physician and an advanced practice provider contribute to the same encounter, the FS modifier and the billing provider are determined by who performed the substantive portion, either more than half the total time or the medical decision making. Billing under the wrong provider is a compliance risk, not just a coding error.
Modifier 25 Applied Without Support
When a procedure and a separately identifiable E/M service happen in the same encounter, modifier 25 has to be backed by documentation showing the evaluation went beyond what the procedure itself required. Missing or unsupported use of this modifier is one of the most common audit triggers in emergency medicine.
Observation Status Disputes
Payers routinely challenge whether a patient should have been placed in observation, held for continued ED-level care, or admitted, and will recoup payment when the coded status does not match their own review of the record.
No Surprises Act Cost-Sharing Errors
Out-of-network ED claims must calculate patient cost-sharing off the qualifying payment amount, and missing the 30-day open negotiation window before initiating IDR forfeits the dispute regardless of how strong the underlying claim is.
Medical Necessity Not Linked to Testing
Labs and imaging ordered during a visit have to tie back to a documented diagnosis to count toward the data-reviewed portion of medical decision making. When that link is missing, the visit level loses part of its supporting evidence.
Our Process
How We Fix It: Our Emergency Department Billing Process
Six steps, each one built to close a specific gap in how emergency department claims typically fail.
Eligibility & Registration Verification
Insurance verification runs in parallel with the medical screening exam so nothing about EMTALA-required care is delayed for a coverage check.
MDM-Based Coding & Leveling Review
Certified coders assign the E/M level based on documented medical decision making, capture every billable procedure, and confirm critical care and trauma activation criteria before anything is scrubbed for submission.
Clean Dual Claim Submission
Professional and facility claims go out separately, correctly modified, with split and shared visit billing assigned to the right provider.
Denial & Downcode Root-Cause Review
Every denial and downcode is traced to its actual cause, then appealed with the specific MDM documentation that supports the original level, and filed within No Surprises Act deadlines where applicable.
AR Follow-Up
Aged claims are worked until payment matches what was billed, including underpayments a standard aging report would miss.
Specialty-Level Reporting
You get visibility into E/M level distribution, denial reasons, and payer-specific downcoding patterns, not just a total collections number.

Frequently Asked Questions
Emergency Department Billing, Answered
How much does emergency department billing cost?
Pricing is set as a custom fee schedule based on your patient volume, acuity mix, and current claim performance, not a flat rate that ignores how your ED actually runs. Most groups see the fee structured as a percentage of collections. Ask us for a quote built around your last quarter of claims data.
How long does it take to onboard a new emergency department client?
Most EDs are fully transitioned within 30 to 45 days, including payer enrollment checks, a parallel-run period against your current biller, and a full audit of open AR. Claims submission and denial follow-up begin well before that window closes.
Can you take over our existing AR and open claims?
Yes. We audit your aged AR first, separate what is still collectible from what needs to be written off, and work the recoverable balance alongside new claims so nothing sits untouched during the transition.
Do you bill professional and facility ED claims separately?
Yes. The physician group's professional claim and the hospital's facility claim follow different coding rules, different forms, and often different payer logic, and our coders handle both sides without collapsing them into one workflow.
How do you handle claims that get downcoded by the payer?
Every downcoded claim is compared against the original medical decision making documentation and the payer's disclosed rationale. Where the record supports the original level, we appeal, and where the No Surprises Act's open negotiation window applies, we file within it.
Are your coders and processes HIPAA compliant?
Yes. Every claim moves through HIPAA-compliant systems and processes, and our coders hold current AAPC or AHIMA certification with ongoing training on CMS and payer-specific ED billing rules.
How do we track our numbers once you take over billing?
You get a recurring performance report broken out by E/M level distribution, denial reason, and AR aging, along with a direct point of contact, so you see clean claim rate and revenue trends without waiting on a quarterly summary to find a problem.
Do you work with emergency departments in every state?
Yes. We support hospital-based EDs, freestanding EDs, and emergency medicine groups across the country and stay current on state-specific Medicaid managed care rules and No Surprises Act variations by state.
