Dental EOBs and Prior Authorization Are About to Get Clearer — Here's What the ADA Is Proposing

Most patients never hear about dental standards committees — and honestly, that's fine. But two documents the American Dental Association just released for public review could quietly fix two of the most frustrating parts of paying for dental care: the unreadable Explanation of Benefits (EOB) and the slow-motion prior authorization process. As a practice that submits insurance claims for patients every day, we think this is worth explaining in plain English.

What is an EOB, and why is yours so confusing?

An Explanation of Benefits is the statement your dental insurer sends after a claim is processed. It's supposed to tell you what was billed, what the plan allowed, what the plan paid, and what you owe. In practice, every insurer formats it differently, uses different terminology for the same thing, and omits different details. Patients regularly call our office believing an EOB is a bill (it isn't), or believing a claim was denied when it was actually paid at a reduced rate. The confusion is not your fault — there has simply never been a national standard for what a dental EOB must contain.

What the ADA is proposing

Proposed ANSI/ADA Standard No. 1120-4 would define the exact data content every dental EOB must communicate — at the individual procedure level — between insurers, dental offices, and practice-management software. In the ADA's own words, the goal is "transparent exchange of adjudicated claim details," fewer administrative follow-ups, and a more predictable picture of what patients owe. If insurers adopt it, an EOB from one carrier would finally contain the same information, described the same way, as an EOB from any other.

Proposed ANSI/ADA Standard No. 1120-5 tackles the other pain point: prior authorization and predetermination. Today, getting an insurer's advance sign-off on a procedure can involve faxes, portals, phone calls, and waits of days to weeks. The proposed standard defines a uniform electronic workflow (built on the same X12 and HL7 FHIR infrastructure medical insurance uses) for submitting, extending, appealing, and canceling authorization requests. For patients, the practical promise is simple: faster answers about whether a procedure is covered before you're in the chair.

The honest caveats

These are proposed standards, open for public comment through August 21, 2026. Even after approval, ANSI/ADA standards are voluntary — insurers are not legally required to adopt them, and adoption timelines in dental insurance have historically been slow. So don't expect your next EOB to look different. But standardization efforts like this tend to set the direction the industry eventually follows, the same way standardized electronic claims did.

What you can do right now

Until the paperwork catches up, the best protections are the ones already available to you:

• Ask for a pre-treatment estimate in writing. For any significant procedure, your dental office can submit a predetermination to your insurer so you see estimated coverage before treatment.
• Know that an EOB is not a bill. If the numbers on an EOB don't match what your dental office quoted, call the office — discrepancies are often processing errors that can be corrected with a resubmission.
• Know your out-of-network rights. PPO plans must pay your benefits regardless of which licensed dentist you choose. We've written a full plain-English guide to how dental insurance billing works and your rights as an out-of-network patient, plus a breakdown of whether dental insurance covers root canals.

Our office submits claims directly for patients on most PPO plans, provides written pre-treatment estimates, and walks you through your EOB if anything looks off. If you have a question about coverage for endodontic treatment, call us at (669) 234-2354 or use our online contact form.
