Electronic data interchange (EDI) enables computer-to-computer exchange of business documents between business partners using a standard, secure connection.

Consider an analogy: It’s like having an English speaker converse with a Russian speaker, with both requiring a translator to bridge the communication gap. They need a third person to translate for both sides. That is the role of EDI: to act as an interpreter for both system A and system B to synchronize data seamlessly.

For numerous decades, EDI has played a vital role in facilitating the exchange of healthcare-related information, including claims, remittance advice, eligibility verification, and prior authorization requests, between healthcare organizations, payers, and providers. Its longstanding implementation underscores its significance in enhancing efficiency and collaboration within the healthcare ecosystem.

Today, covered entities that exchange medical information electronically (health plans, clearinghouses, and care providers) must adopt uniform standards for all healthcare EDI transactions, according to the HIPAA EDI rule. HIPAA EDI compliance requires healthcare organizations to use the ASC X12 protocol when sending PHI documents. 

The ASC X12 protocol is the only acceptable format for HIPAA EDI transactions. This single medical standard serves as a bridge language to connect the computer systems of various healthcare organizations in the US. This seamless integration fosters streamlined operations, eliminates variation between them and makes the exchanges more secure.

In the US healthcare ecosystem, EDI plays a crucial role in solving payment-related challenges. However, data transmission in the healthcare industry is complicated. The sheer amount of data generated by this industry can affect any system’s efficiency, especially when it comes to cybersecurity. Therefore, healthcare providers adopting EDI must adhere to HIPAA regulations and ANSI standards

EDI establishes specific data and document formats for various transactions across industries. Within the healthcare sector, there are nine primary EDI transaction sets, each designated by a unique number:

      • Eligibility benefit inquiry and response (270 and 271): Providers send a benefit inquiry (270) to payers, and payers respond (271) with either an eligibility confirmation or a reason for rejection (such as incomplete or incorrect format). 

      • Claims information (837): Providers use this transaction to either request payment for a claim or provide encounter information.

      • Payment and remittance advice (835): After a provider sends an 837 payment request, the payer will respond with an 835 transaction to document the payment and explain any claim adjustments.

      • Claim status request (276): Providers use this transaction to request the status of a previously submitted claim from the payer.

      • Claim status notification (277): Payers use this transaction to update providers on claim status.

      • Care service review (278): Hospitals use this transaction to request prior authorization for patient service from a payer.

      • Benefits enrollment (834): Employers, unions, government agencies, associations, and payers use 834 to enroll new members in a health plan, manage or change their status, and remove or reinstate them. 

      • Payment order and remittance advice (820): Companies use this transaction to send payment instructions to banks, provide pending payment details to suppliers, and send the premium payment information to payers.

              Leveraging Benefits Of EDI To Drive Real-World Use Cases

              Leveraging Benefits Of EDI To Drive Real-World Use Cases

              EDI has been instrumental in transforming the healthcare industry by facilitating a more efficient, secure transmission of healthcare data. The adoption of it in the healthcare industry has been mandated in the U.S. through legislation such as HIPAA, with other countries following suit.

              To gain a deeper insight into the growing importance of healthcare EDI, let’s explore the remarkable advancements that this technology has ushered into the healthcare industry.

                  • Claims Processing: One of the primary uses of EDI in healthcare is managing insurance claims. Healthcare providers use it to electronically submit claims to insurance companies in a standardized format (typically ANSI X12 837). This electronic claim not only reduces the time and resources required to process claims but also enhances reimbursement speed and cash flow for healthcare organizations. 

                    • Eligibility Verification: Healthcare providers have to verify a patient’s eligibility for healthcare services before providing services. With EDI, they can send an eligibility request to the insurance company and receive an immediate response detailing the patient’s insurance coverage, reducing the risk of errors and improving the efficiency of healthcare operations. 

                    • Payment and Remittance: EDI also simplifies the payment process. Insurance companies can use it to send payment advice (ANSI X12 835) to providers, detailing what has been paid, denied, or needs further explanation. This makes it easier for providers to reconcile claims and payments more efficiently with their records.

                      • Referrals and Authorizations: A referral or authorization is often necessary when a patient needs to see a specialist or requires a specific service. EDI allows healthcare organizations to electronically exchange these referrals and authorizations between healthcare providers, speeding up the process and improving care coordination.

                        • Laboratory Orders and Results: In the lab, EDI is used to automate the process of lab orders and results. A healthcare provider can send an electronic order to a lab, and the lab can return the results when ready. This improves speed, eliminates paperwork, and reduces errors. This integration not only reduces the chances of misinterpretation due to manual entry but also ensures that results are directly integrated into the patient’s EHR.
