EQ*88 in X12 270/271: A Field Guide to Pharmacy
A pharmacy asking whether a patient's drug coverage is active isn't asking the same question as a physician's office checking general plan status, and if a 270 sends EQ*30 when it meant EQ*88, the 271 that comes back can say the plan is fully active while telling the pharmacy nothing about whether the drug benefit itself is in force.
EQ*88 is the EQ segment carrying service type code 88, used in a 270 request to ask a payer specifically about pharmacy benefit coverage rather than general plan status. It is the value a pharmacy-facing eligibility check should send when the downstream question is about drug coverage.
What this element contains
Example
A 270 inquiry scoped specifically to pharmacy benefit coverage rather than general plan status. Synthetic eligibility data.
Where this trips people up
Some payers carve pharmacy benefits out to a separate PBM entirely, so a 271 answering EQ*88 can legitimately point the requester to a different payer ID or come back with a benefit-not-covered response even though the general medical plan is fully active. Test data that always pairs EQ*88 with the same coverage outcome as EQ*30 hides that divergence, and the branch that handles a carved-out pharmacy benefit never gets exercised until a real patient hits it.
