What makes orthodontic billing different from regular dental billing?

A crown is usually billed as one completed procedure. An orthodontic case can run for years, and the payment method depends on the plan. Some plans schedule installments from the initial claim. Others require continuation claims during treatment. Orthodontic coverage also commonly has its own lifetime maximum. Verify the payment schedule, remaining maximum, age limits, and work-in-progress rules before treatment starts.

What is a continuation claim in orthodontics?

A continuation claim is a D8670 claim that some plans require during active orthodontic treatment. It reports periodic care under the existing case and may release the next scheduled installment. Other plans set up automatic payments from the initial claim and do not require another claim. Verify the plan before scheduling continuation claims.

What happens to orthodontic billing when a patient switches insurance mid-treatment?

Re-verify the new plan and confirm that it covers orthodontic work in progress. Ask what takeover documentation it requires. Common items include the original appliance-placement date, remaining treatment months, prior approval, prior EOBs, and the amount already paid. Keep the actual procedure date in Box 24 of the claim form and use the orthodontic fields and Box 35 remarks for the treatment history.

Does orthodontic insurance renew every year or is it a lifetime maximum?

Many dental plans apply orthodontic benefits to a separate lifetime maximum rather than the regular annual maximum, but the plan document controls. Verify the remaining maximum and whether prior payments affect a work-in-progress case. If the patient will age out or lose eligibility during treatment, confirm when future payments stop and update the estimate. Do not assume the benefit resets or prorates.

How do you bill Medicaid for braces?

Medicaid orthodontic rules vary by state. Programs commonly limit coverage to medically necessary cases and require prior authorization with records and the state's assessment form. Continuation-claim requirements also vary. Verify the current provider manual before setting the claim schedule.

Orthodontic Insurance Billing: From Banding to Debond

Orthodontic insurance billing follows one case across months or years of treatment. Verify how the plan pays, file the initial claim when active treatment starts, and then either track the carrier’s automatic installments or submit continuation claims when the plan requires them. Coverage changes and treatment ending both require another review of the case.

Why ortho billing needs a case-level workflow

Orthodontic coverage commonly has its own lifetime maximum. Do not assume it works like the plan’s annual maximum or that prior payments under another carrier will be handled the same way. Verify the remaining maximum and the plan’s work-in-progress rules.

The payment schedule also varies. A plan may release installments automatically from the initial claim, require periodic claims during treatment, or pay in a lump sum. Record the method at verification and build the patient estimate around that schedule.

01 Verify benefits before the consult
02 Build the estimate and contract
03 Band the patient and file the initial claim
04 File continuation claims when the plan requires them
05 Handle mid-treatment insurance changes
06 File the debond claim if the carrier requires it
07 Work AR and reconcile

Verify before the consult

Verify benefits before the consultation. If treatment starts later, verify eligibility again before appliance placement. An ortho verification captures everything a normal verification does, plus the fields that determine how the case will be paid.

The ortho verification checklist

Beyond the usual carrier, group number, effective date, coverage percentage, deductible, and waiting period, an ortho verification captures:

Lifetime maximum and remaining lifetime maximum. The remaining number is the one that matters.
Age limit. Whether the patient will age out during treatment.
Work-in-progress acceptance. Does the plan pay a case that started under another carrier?
Payment cycle. Monthly, quarterly, semi-annual, annual, or lump sum.
Initial (banding) payment percentage. How much pays up front versus over installments.
Continuation-claim requirement. Whether the carrier releases installments from the initial claim or requires additional claims, including the filing interval and documentation.
HMO copays per code. If the plan requires records, consultations, periodic visits, or retention to be reported separately, pull the contracted copays for the codes you will use.

If the patient has two plans, determine which is primary before you file. Read both plans’ coordination-of-benefits provisions instead of assuming the order.

Coordination of benefits, in order

A dependent child on two parents’ plans, with no court order: the birthday rule commonly applies. The plan of the parent whose birthday falls earlier in the calendar year is primary.
A court order: follow the order and the plans’ COB provisions. Do not reduce it to a one-line rule when the order does not name the responsible parent.
Coverage in the patient’s own name plus dependent coverage: the patient’s own plan is generally primary.
Active employee coverage plus retiree or laid-off coverage: the active employee plan is generally primary. When the status is the same, the plan covering the patient longer commonly pays first.
Medicaid plus other liable coverage: bill the other coverage first. Medicaid is generally the payer of last resort.
Medical and dental coverage: do not assume medical is primary. Confirm which plan covers the service and whether either plan requires the other plan’s EOB.

These are common rules, not substitutes for the plan documents. The NAIC coordination-of-benefits model explains the standard order-of-benefit framework.

For the full mechanics, see primary vs. secondary dental insurance.

Build the estimate and the contract

Once benefits are verified, map the treatment to the right CDT code and split the fee so the patient’s financing is correct from day one.

Here is that formula on a real case.

A worked example

Splitting a $6,000 comprehensive case

Sample adolescent case	Amount
Total case fee	$6,000
In-network contractual adjustment	-$300
Insurance estimate (50%, capped at the $1,500 lifetime max)	-$1,500
Down payment at banding	-$1,000
Financed balance (about 22 months, roughly $145 per month)	$3,200

The plan pays 50%, which would be $2,850 on the discounted fee. The ortho lifetime maximum caps the benefit at $1,500, so the family finances the rest. That gap is why you verify the remaining lifetime maximum, not just the coverage percentage. The numbers here are illustrative.

For an in-network case, calculate the estimate from the plan’s contracted allowance. For an out-of-network case, use the plan’s out-of-network allowance and explain that the patient may also owe the difference between that allowance and your fee. The ADA recommends reporting the dentist’s full fee on the claim; the plan then applies its allowance and benefit rules. See the ADA’s guidance on reporting fees.

If the patient will hit an age limit or lose eligibility during treatment, confirm the plan’s cutoff rule and the date future payments stop. Update the estimate instead of assuming the benefit will prorate. Submit claims only for services delivered while the patient is eligible under that plan’s terms.

The initial claim at banding

The initial claim goes out when treatment actually starts, and the date of service is the day you band the patient or deliver the appliance.

A few things that decide whether the initial claim pays clean:

Use the current code that matches the treatment. The active limited-treatment codes are D8010 through D8040 by dentition. Comprehensive treatment uses D8070 through D8090 by dentition, with D8091 reserved for comprehensive treatment associated with orthognathic surgery. Do not use a numeric range as a shortcut because D8050 and D8060 were deleted.
Separate non-covered upgrades from the covered case. Whitening, bracket upgrades, and other patient-selected additions do not automatically belong in the covered orthodontic fee. State them in the patient contract and confirm that the provider agreement permits a separate charge.
Follow the plan’s reporting method. Some plans want only the comprehensive case code. Others require records, periodic visits, or retention to be reported separately. Use the plan’s instructions and contracted fees.

Submit the claim electronically when the payer accepts electronic orthodontic claims. Follow that payer’s filing instructions rather than relying on a general payment-time estimate.

Continuation claims depend on the plan

After the initial orthodontic claim, check whether the plan requires more claims. Some carriers set the payment schedule from the initial claim and release the remaining installments automatically. Others require D8670 claims during active treatment before they will release payment.

TennCare is one example. Tennessee’s Medicaid program allows one D8670 claim for a covered periodic visit per calendar month and requires an orthodontic continuation-of-care form. That is a TennCare rule, not a general rule for Medicaid or commercial plans.

D8670 reports periodic treatment under the existing orthodontic contract. It is not a new fee added to the comprehensive case. Submit it only when the plan requires it and on the plan’s schedule.

Pre-authorization and medical necessity

Some plans require authorization before appliance placement. Others offer a non-binding predetermination but do not require one. Verify the distinction before treatment. When authorization is required, submit the plan’s requested records, which may include a panoramic image (D0330), a cephalometric image (D0340), photographs (D0350), the diagnosis, and the proposed treatment plan. Do not start a case that requires authorization until the approval is on file.

Medicaid orthodontic coverage is program-specific and commonly limited to medically necessary treatment.

If treatment is denied, check whether the exam and records are separately covered before billing them. Do not assume that D8660 or the diagnostic records will pay when the comprehensive case does not.

When a patient switches insurance mid-treatment

Mid-treatment carrier changes are common around employer open enrollment. When a patient changes plans, re-verify the new plan, confirm that it covers orthodontic work in progress, and ask what treatment history it requires.

Do not assume the remarks and prior EOBs are enough. Ask the new carrier for its work-in-progress requirements. Common items include the original appliance-placement date, remaining treatment months, a paid-to-date history, the prior approval, and the total case fee.

Keep the actual procedure date in Box 24. Report the original appliance-placement date in the claim’s orthodontic field and use Box 35 for additional treatment history. A plan’s effective date is not a procedure date. For a field-by-field walkthrough, see the ADA dental claim form guide and the ADA’s current completion instructions.

When a patient transfers out or stops treatment, close the ledger against the care actually delivered and the financial contract.

Transfer-out and dismissed patients

Calculate the fee earned through the termination date under the signed treatment contract.
Post all insurance payments, patient payments, and contractual adjustments received to date.
Notify the payer or submit the termination documentation it requires. If the payer reprocesses the case or requests a refund, post that adjustment from the revised EOB or written request.
Compare the earned fee with the net payments to determine whether the patient owes a balance or is due a refund.

Do not move the projected insurance balance to the patient ledger as a lump sum. Future insurance installments that will never be paid are not automatically patient responsibility. The ADA’s overpayment guidance explains why payer refunds must follow the adjudicated claim history.

Debond and the final payment

At debond, whether you file a final claim depends on the carrier. Some pay the case all-inclusive on the initial claim and need nothing at the end. Others require a debond or retention claim to release the last installment.

Before the expected final payment, verify whether the plan requires a completion or retention claim and which code it accepts. File D8680 only when the retention service was delivered and the code matches the record. Do not submit it solely to release payment.

Working ortho AR

Ortho claims sit in the same aging buckets as everything else, and anything past 30 days needs a reason. On an ortho case, the recurring causes are specific:

A payment posted to the wrong ledger, or lost.
The plan terminated or changed and the new plan has no ortho benefit.
A misquote at verification.
Installments set up at the wrong frequency or amount. This traces straight back to a weak verification.
The initial claim was never actually filed or received. You only catch this by checking claim statuses regularly.

Reconciliation closes the loop: confirm that payments match the deposit report in the PMS, the EOBs, and the bank deposits. Bulk ortho payments often cover several patients on one check, so post each one to the right ledger before you call it reconciled.

The orthodontic CDT code cluster

D8010	Limited treatment, primary dentition
D8020	Limited treatment, transitional (mixed) dentition
D8030	Limited treatment, adolescent dentition
D8040	Limited treatment, adult dentition
D8070	Comprehensive treatment, transitional dentition
D8080	Comprehensive treatment, adolescent dentition (the common case fee)
D8090	Comprehensive treatment, adult dentition
D8091	Comprehensive treatment associated with orthognathic surgery
D8210	Removable appliance therapy for a harmful oral habit
D8220	Fixed appliance therapy for a harmful oral habit
D8660	Pre-treatment exam to monitor growth before banding
D8670	Periodic (continuation) visit, part of the contract
D8671	Periodic treatment visit associated with orthognathic surgery
D8680	Retention: removing appliances and placing retainers
D8695	Removing fixed appliances before treatment is finished

Verify any code against a current source before it goes on a claim. See the full CDT code reference for the rest of the codebook.

When ortho billing becomes a full-time job

A handful of ortho cases is manageable by hand. A practice running steady ortho volume, with continuation claims firing on a dozen different carrier schedules and a wave of January insurance switches to re-verify, is where cases quietly stop paying. The signals: continuation payments that trail off, installment amounts that don’t match the contract, and AR on active cases creeping past 60 days.

That’s the work we do. We verify every case up front, file continuation claims when the plan requires them, work mid-treatment coverage changes, and reconcile installments against the approved case fee. Related reading: how to choose a dental billing company and our insurance billing service.
