Pretreatment estimates and preauthorization

A pretreatment estimate explains how a plan expects to process proposed codes based on current information. It may not guarantee payment if eligibility, remaining benefits, clinical information or the final treatment changes.

A pretreatment estimate is the insurer's written response to a proposed treatment plan, submitted before treatment starts. The practice sends the procedure codes, supporting radiographs and any narrative; the insurer replies with what it expects to pay and what it will not. It is the single most effective way to avoid a surprise bill, because it surfaces the exclusions and downgrades, alternate benefit provisions, missing-tooth clauses, frequency limitations, that are otherwise discovered only when the claim is processed. It is not a guarantee: eligibility can change, the remaining maximum can be consumed by other claims. The final coding can differ from what was proposed. But an estimate that says a procedure will not be covered is reliable in that direction, which is where most of the value lies. Requesting one costs nothing beyond the delay, and that delay is frequently shorter than assumed: many insurers respond within two or three weeks for a complete submission with the right supporting evidence attached.

Before you book: verify pretreatment estimates and preauthorization

  1. 1

    Keep the written response

  2. 2

    Compare it line by line with the treatment plan

  3. 3

    Ask what could make the final payment different

How it works

What actually happens

  1. The practice prepares the treatment plan with the specific procedure codes and tooth numbers
  2. Supporting evidence is attached: radiographs, periodontal charting, photographs, clinical narrative
  3. The insurer reviews it against your policy and returns a written response
  4. The response states the expected payment, the patient portion, and any procedures not covered
  5. You and the practice review it before treatment is scheduled
  6. Treatment proceeds with a realistic expectation of the final bill

When it is most worth doing

Situations where an estimate pays for itself

Two further cases fit no single row: periodontal surgery and other major services, and any treatment where you would change your decision if the plan paid nothing.

FactorDetail
CrownsAn alternate-benefit provision may pay only toward a filling
Implants and graftingCommonly excluded or limited
BridgesA missing-tooth clause may apply
OrthodonticsLifetime maximums and age limits apply
SedationOften excluded when provided for anxiety alone
Multi-stage treatmentThe annual maximum may be reached partway through

The limits

What a pretreatment estimate does not do

!

It does not guarantee payment: eligibility can change between the estimate and the treatment

!

It assumes the remaining annual maximum is still available; other claims can consume it in the meantime

!

The final coding must match what was submitted, or the response may differ

!

It generally has an expiry period, after which it may need resubmitting

!

It does not bind the insurer if the clinical situation changes once treatment begins

!

A negative response is more reliable than a positive one. An exclusion is unlikely to become coverage

If the answer is disappointing

What to do with an unfavourable estimate

  1. Ask which specific policy provision is being applied, by name
  2. Check whether the codes submitted accurately describe the planned treatment
  3. Ask whether additional clinical evidence, better radiographs, a narrative, charting, would change the assessment
  4. Consider whether an alternative treatment that is covered would be clinically acceptable
  5. Ask the practice whether staging across benefit years would help
  6. Where a denial appears to misapply the policy, use the formal appeal process

Questions people ask

Common questions

01

Is a pretreatment estimate the same as preauthorization?

The terms are used loosely and sometimes interchangeably, but there is a distinction worth knowing. A pretreatment estimate or predetermination tells you what the plan expects to pay; preauthorization or prior authorization is a requirement that the insurer approve treatment before it happens, without which a claim may be denied outright. Ask the insurer which applies to your plan and to the specific procedures proposed. The consequence of skipping one differs from the other.

02

How long does a pretreatment estimate take?

It varies by insurer, and it does introduce a delay before treatment can start. That is the main argument against obtaining one, and it is a real consideration for anything urgent. For elective or major treatment, the delay is usually worth it. If the treatment is urgent, the sensible approach is to proceed clinically and accept the uncertainty instead of to delay necessary care for paperwork.

03

Is the estimate binding on the insurer?

Generally not. It is an estimate based on your eligibility and remaining benefits at the time of review, and those can change: most commonly because other claims consume the annual maximum in the interim, or because eligibility lapses. The final coding also has to match what was submitted. Where the estimate says something is excluded, however, that is reliable in practice, and avoiding that surprise is where most of the value sits.

04

Should I always get one?

Not for routine care: the delay is not worth it for a cleaning or a small filling. It is worth it whenever the amount is significant, whenever an exclusion or downgrade is plausible, and above all whenever the answer would change your decision. Crowns, implants, grafting, bridges, orthodontics and sedation are the categories where estimates most often prevent a genuine surprise.

05

My estimate came back much lower than expected: what now?

First establish which policy provision is being applied and whether the submitted codes accurately describe the plan. Alternate-benefit downgrades and missing-tooth clauses are the usual culprits and are contractual instead of errors. Ask whether additional clinical evidence would change the assessment, whether a covered alternative would be clinically acceptable, and whether staging across benefit years helps. If the provision appears misapplied, appeal formally.

06

Does the practice submit the pretreatment estimate, or do I have to?

The practice normally prepares and submits it, since they hold the procedure codes, radiographs and clinical narrative the insurer needs to review. Ask them directly to submit one before scheduling anything substantial, not assuming it happens automatically, not every practice does this by default, and it is a reasonable, ordinary request instead of an imposition.

07

Does an estimate expire?

Generally yes. Most insurers set an expiry period after which a pretreatment estimate is no longer valid and may need resubmitting, particularly if your eligibility, remaining maximum or the treatment plan itself has changed in the meantime. If treatment is delayed for any reason, ask whether the original estimate still applies before assuming it does.

08

What information does the insurer need to review one?

The specific procedure codes and tooth numbers being proposed, plus supporting evidence such as radiographs, periodontal charting, photographs or a written clinical narrative explaining why the treatment is necessary. Incomplete submissions are one of the most common reasons a response comes back as a denial or downgrade instead of approval. The insurer is responding to what was submitted, not to the full clinical picture.

09

Can I request a pretreatment estimate myself, without going through the dentist?

Some insurers will discuss general plan terms directly with you, but the estimate itself requires the specific procedure codes and supporting clinical evidence, which only the treating practice can supply. The practical route is always to ask the practice to submit it: a policyholder calling the insurer directly usually cannot provide the clinical detail an estimate review actually depends on.

10

Is a pretreatment estimate worth the delay for something time-sensitive but not urgent?

Usually yes if the amount involved is significant, and the delay is real but often shorter than people assume: many insurers respond within a couple of weeks. Weigh the delay against the size of a potential surprise: for a small filling it rarely matters, for a crown, implant or bridge the estimate frequently changes the treatment decision itself, which makes the wait worthwhile.

11

Does getting a pretreatment estimate cost anything?

No: it is a standard part of how dental benefits are administered and insurers do not charge for reviewing one. The only cost is the delay before treatment can proceed, and any additional time the practice spends preparing supporting documentation, which is not typically billed separately either.

12

Does a pretreatment estimate need to be resubmitted if the treatment plan changes?

Yes, generally: the estimate is reviewed against the specific procedure codes and clinical evidence submitted, so a materially different plan (a different tooth, an added stage, a changed material) may need its own estimate to be reliable. If the treating dentist revises the plan after an estimate is already in hand, ask whether the change is significant enough to warrant resubmission.
