Portal verification vs the 271

A 271 answers one question well: is this coverage active? Dental treatment decisions need different answers — what this procedure pays for this tooth, given this patient's history, clauses and remaining maximum. Those facts live in the payer portal. They are mostly absent from the electronic response, which is why “verified” patients still produce denials and write-offs.

Fact271 (EDI)Payer portal
Coverage active / inactiveYes — its core jobYes
Annual maximum & deductible remainingOften, varies by payerYes, from the payer's own record
Procedure-level (CDT) coverage %Category-level at bestYes, per scheduled code
Tooth-level benefitsNo — the 271 has no tooth segmentYes where the portal exposes it
Frequency limits vs procedure historyStedi's own reliability table: dental “sometimes”Yes, checked against history
Missing-tooth / replacement clausesNot typically returnedYes
Waiting periodsNot typically returnedYes
Downgrades (e.g. composite → amalgam rate)Not typically returnedYes
Treatment history affecting this visitNoYes where the portal exposes it
Typical transaction cost$0.08–$0.30 per check (Stedi published pricing)Replaces a 12–20 minute staff task (CAQH manual cost $6.52/transaction)

What this means in dollars

EDI checks cost pennies ($0.08–$0.30 at Stedi's published tiers) because they replace a $2.53 electronic transaction (CAQH Index). A manual benefits breakdown — the work a portal verification replaces — takes staff roughly 12–20 minutes and is exactly the work busy front desks skip, downgrading verification to a seconds-long active check. Each denied claim that follows costs $25–$118 to rework (HFMA/MGMA), before the write-offs that never get worked at all. Sally prices the two answers separately: $1.25 for the electronic answer, $5.99 for the portal-verified visit — see the full price card.

Is a 271 response enough to quote a patient's out-of-pocket cost?

Usually not for planned treatment. The 271 confirms eligibility and some benefit amounts, but procedure-level detail — frequencies, clauses, downgrades, tooth-level rules — is typically absent, which is why offices still fall back to payer portals and phone calls before quoting treatment.

Why is portal verification priced higher than an EDI eligibility check?

They replace different work. An EDI check replaces a $2.53 electronic transaction (CAQH Index) and answers whether coverage is active. A portal verification replaces a 12–20 minute manual benefits breakdown and prevents the write-offs that follow clause and frequency surprises. Denied-claim rework alone runs $25–$118 per claim (HFMA/MGMA).

When is the cheap electronic check the right tool?

For active/inactive screening at volume — recall lists, schedule hygiene, coverage discovery. Sally sells that tier too ($1.25). Planned treatment with money attached deserves the portal answer.
