Electronic Data Interchange (EDI) is often associated with shipping and supply chains. But EDI plays a major role in healthcare as well, helping providers and insurers exchange critical information quickly and accurately.
One important example is the EDI 278 transaction set, which handles service review requests and responses. This document allows hospitals, clinics, and other healthcare providers to request approvals for procedures, referrals, and certifications from insurers — without relying on phone calls or faxes.
In this guide, we’ll explain what an EDI 278 transaction is, its key components and benefits, and its impact on the healthcare industry.
What Is the EDI 278?
The EDI 278 (Healthcare Services Review Information) document follows the ANSI ASC X12 standard, a widely used format for electronic data exchange. While this standard applies across multiple industries in North America, the EDI 278 is specifically designed for healthcare.
This EDI 278 allows healthcare providers and insurers to communicate efficiently by digitizing authorization, certification, and referral requests. Instead of relying on paper forms, faxes, or phone calls, providers can submit requests electronically, speeding up approvals and reducing administrative work.
By replacing manual processes with standardized communication, the EDI 278 keeps data structured and consistent across hospitals, clinics, and insurance companies. This reduces errors, prevents miscommunication, and helps maintain accurate records.
HIPAA Compliance and Data Security
Like other EDI documents, the EDI 278 follows a structured format that keeps information organized and easy to process (more on that below). However, because it transmits sensitive patient information, it must also comply with strict Health Insurance Portability and Accountability Act (HIPAA) regulations. These rules protect patient privacy, support secure communication, and establish a consistent way for healthcare systems to exchange information.
Keeping patient data safe: HIPAA requires that all electronic health records be encrypted and only accessible to authorized personnel. Secure transmission methods help prevent data breaches and unauthorized access to patient information.
Standardizing healthcare communication: A HIPAA-compliant EDI 278 ensures that hospitals, insurers, and clinics use the same structured format for sharing data. This consistency reduces errors, speeds up approvals, and improves coordination between healthcare providers and payers.
Avoiding costly penalties: Organizations that don’t follow HIPAA regulations can face serious fines and legal consequences. Using secure, compliant EDI systems helps protect patient data and ensures that healthcare providers meet industry standards.

Now, to better understand how an EDI 278 transaction works, let’s take a closer look at the sample document’s main sections, including patient and service information and other important data segments:
Parties Involved in the Authorization Request
Every EDI 278 document includes key details about the healthcare entities involved in the authorization request. These segments confirm who is submitting the request, who is reviewing it, and who the patient is.
Payer information: This identifies the insurance company or payer processing the authorization request.
Provider information: This specifies the healthcare provider or facility requesting the authorization.
Patient information: This contains details about the patient, including demographics and insurance identification.
Patient and Service Request Details
Once an authorization request is made, the EDI 278 document provides a full breakdown of the services being requested. This section ensures accurate processing and decision-making by the payer.
Transaction purpose: This specifies whether the request is for initial approval, extension, or modification of a healthcare service.
Service information: This details the type of service requested (e.g., inpatient, outpatient, diagnostic) and any supporting medical necessity information.
Authorization tracking: This includes a unique reference ID for tracking the request and response.
Key EDI 278 Data Segments
The EDI 278 document consists of specific segments, each serving a distinct function to structure authorization requests, patient details, and service information in a standardized format:
ISA/IEA (Interchange Control Header and Trailer): This denotes the sender, receiver, and technical details of the EDI exchange.
BHT (Beginning of Hierarchical Transaction): This establishes the purpose of the transaction, including reference ID and date.
HL (Hierarchical Levels): Here, the EDI 278 organizes the transaction into payer, provider, and patient levels.
PAT (Patient Event Level): This includes patient-specific information such as demographics, insurance details, and account numbers.
UM (Utilization Management Segment): This defines service request details, including the type of care, certification, and duration.
PER (Contact Information): This lists contact details for the involved parties, including phone numbers and email addresses.
7 Benefits of EDI 278
Getting approval for medical services can take time, especially when relying on phone calls, faxes, or paperwork. The EDI 278 helps speed up this process by allowing healthcare providers and insurers to exchange authorization requests electronically. This not only reduces delays but also improves accuracy and keeps records organized.
Let’s look at the main benefits the EDI 278 offers:
1. Faster Approvals
Manually processing referrals, certifications, and authorizations takes time and prevents patients from receiving the care they need when they need it. The EDI 278 automates these exchanges so that healthcare providers can focus on prioritizing people, not paperwork.
2. Clearer Communication Between Providers and Insurers
Since the EDI 278 follows a standardized format, hospitals, clinics, and insurance companies can process service requests more efficiently without misunderstandings. This reduces errors and helps prevent unnecessary delays.
3. Quicker Turnaround for Requests and Authorizations
Waiting for faxes, phone calls, or mailed forms can slow down patient care. With the EDI 278, providers receive real-time responses, which means faster approvals for procedures, specialist referrals, and treatments.
4. More Informed Decisions for Insurers
The EDI 278 packages patient data in a structured way that ensures accuracy, and this allows insurance companies to review medical necessity, verify coverage, and process approvals more efficiently. This leads to fewer claim denials and better alignment with policy guidelines.
5. Stronger HIPAA Compliance and Data Protection
In the United States, the EDI 278 is required to follow HIPAA regulations so that patient data is securely exchanged between authorized parties. This is vital to keeping sensitive patient information safe, preventing unauthorized access, and maintaining compliance with healthcare privacy laws.
6. Lower Administrative Costs
Manually handling authorization requests takes time, increases labor costs, and leads to errors. By automating these processes, the EDI 278 reduces expenses while also making healthcare operations more efficient.
7. Improved Patient Experience
Thanks to the EDI 278, providers and insurers can exchange information instantly, speeding up approvals and reducing long wait times. In healthcare, where every second counts, faster decisions mean quicker treatment and better patient care.
4 Common EDI 278 Issues and How to Solve Them
The EDI 278 helps healthcare providers and insurers process authorizations faster, but it also has its challenges. Some organizations struggle with technical difficulties, high costs, security risks, and system compatibility issues. Here’s a closer look at these challenges and how to solve them.
1. Technical Challenges
Hospitals and clinics need to focus on patient care, not complex data systems. But setting up an EDI system and making sure it works correctly can be complicated — especially for those unfamiliar with how electronic data is structured and transmitted.
To simplify the process, many healthcare organizations partner with an EDI provider that handles everything for them, from setup, integration, and training to security and ongoing support.
2. Budgetary Concerns
Building an EDI system from scratch can be expensive — costs for hardware, software, and IT specialists add up quickly. Cloud-based EDI providers, which charge a monthly subscription fee, are often a more budget-friendly alternative. For many organizations, these third-party solutions are not only more affordable but also easier to maintain over time.
3. Data Security and HIPAA Compliance
Because EDI 278 transmits private patient information, it must meet strict HIPAA security rules to prevent data leaks or unauthorized access. If the right protections aren’t in place, providers risk data breaches, legal trouble, and loss of patient trust.
To prevent this, healthcare organizations need to use encrypted EDI systems, limit access to only authorized users, and conduct regular security audits. Training employees on how to handle patient data safely is also vital to reducing risks.
4. Integration Challenges
Most healthcare organizations use electronic health records (EHR) to manage patient care, but the EDI 278 doesn't automatically integrate with every system. Avoid this by choosing EDI software that works well with your current setup or partnering with an EDI provider that can bridge any gaps between different technologies.
