Testing X12 270/271 EB02: What Coverage Level Code Actually Needs to Handle

Jul 27, 2026 · 4 min read

The same plan can quote a $500 individual deductible and a $1,500 family deductible in adjacent EB segments. Ignore EB02 and your system has a 66% chance of applying the wrong number to the patient in front of you.

Quick answer

EB02 is the Coverage Level Code in an X12 271 EB segment — it states whether the benefit amounts in that segment apply to the individual, the family, or a specific tier like employee-plus-spouse.

Valid code values

IND

Individual — amounts apply to the single subscriber or dependent

FAM

Family — amounts apply to the family aggregate

ESP

Employee and Spouse — amounts apply to that specific tier

ECH

Employee and Children — amounts apply to that specific tier

EMP

Employee Only — amounts apply to the employee alone

Example

Synthetic example Generated by Synthibase

EB*C*IND*30**Acme PPO Bronze*27*500.00**22*

EB02 = IND means the 500.00 deductible in EB07 applies to this individual, not the family aggregate. Synthetic 271 response data.

Where this trips people up

Payers commonly return separate EB segments for the same EB01/EB03 combination, one at IND and one at FAM, back to back. Logic that grabs "the first deductible segment it finds" without checking EB02 will sometimes surface the family figure to a patient asking about their individual responsibility, which does not match what they get billed later.
