ER Billing

Emergency Room (ER) billing is a critical part of the healthcare revenue cycle. It involves the submission of claims for emergency medical services provided to patients in an ER setting. Given the urgent nature of emergency care, ER billing must be accurate, efficient, and compliant with a variety of payer requirements, insurance policies, and healthcare regulations.

This article explores the fundamentals of ER billing, the challenges associated with it, and how ARCDOTT RCM Solutions can assist in improving ER billing through its specialized Revenue Cycle Management (RCM) expertise.

What is ER Billing?

ER billing refers to the process of submitting claims for reimbursement for medical services rendered in an emergency room. These services can range from immediate care for life-threatening injuries or conditions to diagnostic tests, procedures, medications, and consultations by specialists.

Because emergency room visits involve a broad range of services — some life-saving and others less critical but still requiring medical intervention — ER billing can be complex. Providers must use accurate coding and follow detailed documentation practices to ensure correct reimbursement from both insurance companies and patients.

Key Components of ER Billing
ER billing involves several crucial components that need to be handled meticulously for timely and correct reimbursement.
CPT Codes for ER Services

Current Procedural Terminology (CPT) codes are used to describe the services provided in the ER. These codes specify everything from routine office visits to high-level emergency procedures. The level of care required will determine which CPT code is used.

For example:

          • 99281-99285: These codes are used to classify the level of emergency room visits, from the least complex (99281) to the most complex (99285).
          • 94010-94799: Codes for respiratory services (e.g., oxygen therapy or nebulizer treatments).
          • 30000-39999: Codes for surgical procedures performed in the ER, such as wound repairs, chest tube insertions, or fracture reductions.
Proper selection of these codes is crucial because the accuracy of the CPT code directly influences the reimbursement received.
ICD-10 Codes for ER Diagnosis

ICD-10 (International Classification of Diseases, 10th edition) codes are used to document the patient’s diagnosis and justify the procedures and treatments provided in the emergency room. These codes link the patient’s symptoms and condition to the appropriate services.

For example:

    • I21.9: Acute myocardial infarction (heart attack) requires specific diagnostic procedures, such as blood tests, EKG, and imaging, all billed accordingly.
    • S06.0X0: Concussion due to head injury, requiring imaging or observation in the ER.
    • T14.91: Unspecified injury, which might necessitate further investigation and testing.
These codes need to be properly assigned to reflect the medical necessity of the ER services provided, enabling successful reimbursement from insurance payers.
ER Level of Service (LOS) Determination
In ER billing, the Level of Service (LOS) is determined based on the severity of the patient’s condition and the complexity of the services provided. ER levels of service range from Level 1 (low complexity) to Level 5 (high complexity). The level chosen is typically based on:
    • Patient’s presenting condition (e.g., life-threatening or routine).
    • Diagnostic procedures (e.g., imaging, lab work).
    • Treatments administered (e.g., medication, wound care).
    • Time spent (some insurers also use time-based billing in ERs).
Each level is associated with specific CPT codes, which correspond to the type of care provided. Accurate documentation of the patient’s condition and treatment ensures the correct level is billed.
Insurance Verification and Pre-Authorization

Before ER services are rendered, it’s essential to verify the patient’s insurance coverage. While most ER visits are covered by insurance, especially in emergency situations, verifying the patient’s coverage ensures that the provider knows what will be covered and what the patient’s financial responsibility will be. Some procedures or specialty consultations in the ER may require pre-authorization from the insurance company.

For example, an advanced imaging procedure like an MRI may require pre-authorization, even if it is being conducted in the emergency room setting.

Claim Submission and Documentation

Once the services are provided, claims must be submitted to the insurance provider. The claims include the appropriate CPT codes, ICD-10 codes, and supporting documentation that justifies the medical necessity of the services rendered. This documentation may include medical records, imaging results, and lab test reports.

Failure to submit accurate claims or provide sufficient documentation can lead to denied claims, delayed payments, or underpayment.

Patient Billing and Collections

After insurance payments are processed, ER providers need to manage patient billing for any out-of-pocket costs, including co-pays, deductibles, and coinsurance. Given the emergency nature of ER visits, it’s crucial to ensure that patients are informed of their financial responsibilities ahead of time, which can be challenging in an urgent setting.

Timely and clear billing is key to receiving prompt payment from patients. Practices may offer payment plans or other options for patients who face financial hardships.

Payment Posting and Reconciliation
Once payments from both insurance and patients are received, they need to be posted correctly into the practice’s financial system. This involves reconciling payments against the submitted claims to ensure the amounts are correct. Discrepancies should be resolved immediately to ensure the practice is paid in full.
Common Challenges in ER Billing
Despite its importance, ER billing comes with several challenges:
          1. Complex Coding and Documentation: Given the wide variety of services and the often-urgent nature of ER visits, correct coding can be difficult. Incorrect use of CPT or ICD-10 codes can result in claim denials or underpayment.
          2. Varying Insurance Policies: Different insurance companies have different policies regarding ER care, including how much they will reimburse, which procedures are covered, and which are not. Navigating these complexities can be challenging.
          3. Pre-Authorization Delays: Many ER procedures, especially those that are not life-threatening but require advanced imaging or specialty consultations, require pre-authorization. Delays in obtaining these authorizations can delay services and lead to payment issues.
          4. High Volume of Claims: ERs see a high volume of patients, which can lead to a high volume of claims. Managing these claims effectively while maintaining accuracy is essential but can be difficult without a streamlined process.
          5. Patient Financial Responsibility: In emergency situations, patients may not fully understand their financial obligations. This can lead to confusion and delays in payment.
          6. Claim Denials: Errors in coding, documentation, or submission can lead to denied claims, requiring time-consuming follow-up efforts.
