Opening an emergency room (ER) — whether a hospital-based emergency department or an independent, freestanding emergency medical care facility — is a complex, highly regulated, and capital-intensive undertaking. However, given the critical role these facilities play in community health and the growing demand for acute care access, establishing a compliant and financially sustainable ER can be rewarding for clinicians, health systems, investors, and communities alike.

This guide breaks down the essential steps and requirements for starting and setting up an emergency room in Texas or around the USA — from legal/licensing prerequisites and physical setup to staffing, workflow, billing, and how Right Medical Billing can be a strategic partner through the entire process.

I. Understanding the Types of Emergency Rooms

Before diving into setup, it’s essential to clarify the types of ERs you might establish:

1. Hospital-Based Emergency Departments

These are traditional ERs located within a licensed hospital. They are governed by federal laws like EMTALA (Emergency Medical Treatment and Labor Act), state hospital licensing requirements, and Medicare/Medicaid conditions of participation. Most full ERs operate 24/7 and are capable of handling critical, high acuity care.

2. Freestanding Emergency Departments (FSEDs)

Freestanding ERs are emergency care facilities that operate independently of a hospital building. They provide emergency care services — often 24/7 — but are a distinct licensure category in states like Texas.

These facilities have become an alternative to hospital ERs for areas underserved by acute care.

II. Regulatory & Licensing Requirements

A. Texas State Licensing (Freestanding ER)

If you’re planning a freestanding emergency medical care facility in Texas:

State License Required: Texas law mandates a license issued by the Texas Health and Human Services Commission (HHSC) to operate as a freestanding emergency medical care facility.
Continuous Operation: The facility must be open 24 hours a day, 7 days a week.
Doctor Availability: A physician must be available at all times, either on-site or within a specified time to reach the facility.
Facility Standards: The Texas Administrative Code sets out detailed facility construction and design standards — e.g., emergency suite layout, treatment rooms, nurse station configuration, and signage.
Disclosure & Fee Transparency: Texas law requires freestanding emergency centers to provide disclosures about facility fees, insurance network status, and billing practices in both English and Spanish.

These requirements ensure patient safety, quality of care, and transparency.

B. Regulatory Requirements in Other States

Each state in the U.S. has its own requirements for ER or outpatient emergency facility licensing. Some states may require a Certificate of Need (CON) before establishing a new healthcare facility — a regulatory tool designed to demonstrate community need and avoid duplication of services.

For hospital-based ERs, licensure falls under broader hospital regulation and oversight (state health departments + CMS Conditions of Participation).

C. Federal Standards

If the ER participates in federal programs (e.g., Medicare/Medicaid), facilities must comply with federal standards for patient rights, staff qualifications, quality assurance, billing compliance, and patient privacy (HIPAA).

III. Business, Financial & Market Planning

Before construction or licensing, you need a comprehensive business and market plan.

1. Market Analysis

Population demand for emergency care
Competitive landscape: nearest ERs or urgent care centers
Insurance mix (commercial vs Medicare/Medicaid)
Payer contracts and reimbursement expectations

2. Financial Modeling

Startup capital (facility construction, medical equipment, IT systems)
Operating costs (staff salaries, supplies, utilities, malpractice insurance)
Revenue projections based on projected patient volumes and payer mix

3. Legal & Corporate Structuring

Entity formation (LLC, corporation)
Professional liability coverage
Provider contracts and medical directorship arrangements

IV. Physical Setup & Construction

1. Facility Location & Zoning

Comply with local zoning laws
Accessibility for ambulances and patients
Parking and public access

2. Facility Design & Safety Standards

Emergency room layouts must accommodate:

Triage, registration, treatment rooms
Diagnostic imaging (X-ray, CT if offered)
Lab services or point-of-care testing
Nurse station visibility and patient flow
Clean room standards

For freestanding ERs in Texas, the state code specifies clear guidelines for emergency suite layout, room size, handwashing fixtures, signage, and work areas.

3. Medical Equipment

Depending on the services offered:

Resuscitation cart & crash cart
Monitors and imaging
Ventilators and airway equipment
Defibrillators, infusion pumps
Laboratory and point-of-care testing devices

4. Information Systems

Electronic Health Record (EHR) that supports emergency workflows
Billing and Practice Management Software
Connectivity with local hospitals and referring providers

V. Staffing & Credentialing

1. Clinical Staff

Board-certified emergency physicians (or Credentialed emergency medicine clinicians)
Advanced Practice Providers (NPs/PAs) trained in emergency care
Registered nurses with ACLS/PALS certifications
Radiology and lab personnel if diagnostic services are offered

Texas law, for example, outlines physician availability requirements and ongoing operational standards.

2. Support & Administrative Staff

Front-desk and registration team
Medical coders and billers (highly specialized for ER)
Compliance officer
Practice manager

3. Credentialing with Payers

Every physician and provider must be credentialed with insurance companies to ensure patient claims are reimbursable. Credentialing can take 90+ days and requires submission of provider licenses, training certificates, malpractice history, and more.

VI. Billing, Coding, & Revenue Cycle Management

Your ER’s financial success hinges on accurate billing, compliant coding, timely claims submission, and rigorous AR (Accounts Receivable) follow-up.

1. Dual Billing Model

Emergency rooms typically bill:

Facility Charges: Based on facility fee schedules
Professional Services: Physician evaluation and management (E/M) services and procedures

This dual model adds complexity and increases risk of denials without expert billing processes.

2. Coding Complexity

Emergency medicine involves many high-level E/M codes (99281–99285), critical care codes (e.g., 99291), and use of multiple modifiers. Proper use of modifiers like Modifier 25 (same-day significant, separate E/M) or Modifier 59 (distinct procedural service) is crucial for reimbursement. Right Medical Billing

3. Compliance & Payer Rules

Freestanding ERs, especially in Texas, often operate out of network, exposing patients to higher cost sharing. Texas law and federal “No Surprises Act” rules add transparency and balance billing restrictions, requiring clear disclosures about expected costs and network status. Right Medical Billing

4. Claim Denials & AR Management

ER claims are frequently denied due to:

Coding errors
Lack of medical necessity documentation
Missing modifiers
Payer policy layers

Without expert revenue cycle management (RCM), ROI suffers dramatically.

VII. Marketing & Patient Access

1. Branding & Positioning

Your ER’s website, local search presence, and community education materials must be clear about:

24/7 care availability
Emergency services offered
Insurance acceptance
Billing transparency and patient rights

2. Community Outreach

Partnerships with local EMS, urgent care centers, and primary care providers can improve referral access and appropriate use of services.

IX. Cost Estimation, Staffing Requirements, and Essential Facilities for an Emergency Room

One of the most critical components of successfully starting and operating an emergency room in Texas or anywhere in the United States is having a realistic understanding of startup costs, ongoing operational expenses, staffing needs, and required facilities. Underestimating these factors can significantly impact cash flow, compliance, and long-term sustainability.

A. Cost Estimation for Setting Up an Emergency Room

The cost of establishing an emergency room varies widely depending on whether it is a hospital-based ER or a freestanding emergency department, geographic location, size, and service scope. Below is a realistic breakdown of typical expenses:

1. Initial Capital Investment

Facility Construction or Leasehold Improvements:
$2 million to $6 million+ depending on size, zoning, and local construction costs.
Medical Equipment & Diagnostic Tools:
$750,000 to $2 million, including imaging, resuscitation equipment, monitors, and lab tools.
IT Infrastructure & EHR Systems:
$150,000 to $400,000 for EHR, billing software, cybersecurity, and network setup.
Licensing, Legal, and Consulting Fees:
$75,000 to $200,000 covering state licensure, legal structuring, compliance consulting, and inspections.
Initial Staffing & Training Costs:
$300,000 to $600,000 (pre-opening hiring, credentialing, and onboarding).
Marketing & Community Outreach:
$25,000 to $75,000 for branding, website development, and local awareness campaigns.

Estimated Total Startup Cost:
$3.5 million to $8+ million, depending on scale and service depth.
