Healthcare EDI, Decoded: 837 Claims, 835 Remittances, and the 270/271 Eligibility Handshake
Healthcare EDI runs on four transactions, and none of them forgive sloppy tooling. Retail EDI moves boxes: an 850 orders them, an 856 says they shipped, an 810 asks to be paid. Healthcare EDI moves money for care already delivered, and the documents carry the proof. The 837 is the claim — the bill a provider sends a payer. The 835 is the remittance — the payer's answer, with the check attached.…
Healthcare Electronic Data Interchange (EDI) operates on four primary transactions: 837 claims, 835 remittances, and the 270/271 eligibility handshake. These transactions are crucial for billing and payment processes in the healthcare industry. Unlike retail EDI, which handles shipping and payment of goods, healthcare EDI deals with the financial aspects of delivered care.
The 837 claim is a bill that providers send to payers, detailing the services rendered, the charges, and the patient information. There are three types of 837 claims: 837P for professional services, 837I for institutional services, and 837D for dental services. Each claim contains a wealth of information, including the billing provider, subscriber, patient, service lines, charges, and diagnosis codes. However, even small errors in these details can cause an 837 to be rejected or denied by the payer.
The 835 remittance advice is the payer's response to the claim, indicating whether the claim was paid, partially paid, or denied. It includes payment information, adjustment reason codes, and details on any insurance coverage or patient responsibility. Unlike the 837, the 835 can reveal hidden errors and discrepancies that may not be immediately apparent, such as charge exceeding the contracted fee schedule or the patient's deductible being applied incorrectly.
The 270 eligibility inquiry and 271 response are essential for determining whether a patient is covered for a specific service on a given date. The 270 asks if the patient is covered, while the 271 provides details on the patient's benefits, copays, deductibles, and remaining balances. However, eligibility checks are often overlooked or misunderstood in healthcare EDI, as a "yes" to coverage doesn't guarantee payment.
Additional factors, such as authorization requirements or the timing of the service, must also be considered.
Healthcare EDI relies on acknowledgments and natural key identifiers to ensure transactions are properly routed and processed. Acknowledgments confirm the receipt and acceptance of the transactions, while natural keys, such as control numbers and trace numbers, help detect duplicate submissions. However, even with these safeguards, errors can still occur, as denials may surface weeks after the initial submission.
In summary, healthcare EDI transactions are complex and crucial for the financial health of providers and payers. Proper validation, acknowledgment, and partner-specific compliance are essential to ensure accurate and timely processing of claims, remittances, and eligibility checks.
