Understanding the Most Common Eligibility Errors in Healthcare EDI
In healthcare, accurate eligibility verification is critical for ensuring timely claims processing and avoiding costly rework. Electronic Data Interchange (EDI) transactions, particularly the 270 (Eligibility Inquiry) and 271 (Eligibility Response), are key tools for checking a patient’s insurance coverage. However, even with automation, eligibility errors are still common – and they can seriously impact patient care and revenue cycle performance. Here are some of the most frequent eligibility errors, along with real-world examples.
1. Incorrect Patient Information
What happens: The most common reason for eligibility errors is incorrect demographic data – such as name, date of birth, or insurance ID number.
Example: A claim is denied because the patient’s name was submitted as “Jon Smith” instead of “Jonathan Smith,” which doesn’t match the payer’s database.
Solution: Always validate patient details at registration and double-check them before submitting the 270 inquiry.
2. Coverage Terminated or Not Effective
What happens: If a provider submits a 270 inquiry and receives a 271 response showing inactive coverage, it could mean the patient’s insurance has expired or hasn’t yet started.
Example: A patient visits on June 1st assuming their new plan is active, but the 271 shows a start date of July 1st. Services rendered may not be reimbursed.
Solution: Educate staff to verify the exact start and end dates of coverage before appointments.
3. Wrong Payer or Plan Selected
What happens: Submitting to the wrong payer or using outdated payer IDs leads to incorrect or failed responses.
Example: A provider sends an eligibility check to a commercial insurer when the patient recently switched to Medicaid. The 271 returns “No coverage found.”
Solution: Use a payer list updated regularly, and confirm the payer with the patient directly if there’s any doubt.
4. Misinterpretation of the 271 Response
What happens: Eligibility data in the 271 file can be complex and misread, especially when dealing with nested benefits.
Example: A provider misinterprets a message indicating “coverage exists but not for physical therapy,” and incorrectly assumes full coverage.
Solution: Use EDI software that clearly translates 271 responses into readable formats and train staff to interpret them correctly.
Eligibility errors can disrupt care and delay payments, but most are avoidable with better data entry, staff training, and smart EDI tools. Prioritizing clean eligibility checks helps providers offer smoother patient experiences and stronger financial performance.
