How Long Does a Dental Office Have to File a Claim? Timely Filing Limits Explained

A timely filing limit is the window after a date of service inside which a claim has to reach the payer.

Miss the window and the plan can deny the claim for lateness alone — the treatment can be charted, coded, and documented perfectly and the claim still go unpaid.

There is no single window.

Two deadlines are set by public rules.

Medicare claims must be filed no later than 1 calendar year after the date of service (42 CFR 424.44) — most routine dental care is not a Medicare benefit, so this deadline matters mostly when a practice cross-bills a covered service to a medical payer, and the regulation carries exceptions at 42 CFR 424.44(b) and (e).

Federal Medicaid rules, meanwhile, require each state Medicaid agency to make providers submit all claims no later than 12 months from the date of service (42 CFR 447.45(d)(1)).

Everything else — the commercial dental plans a practice bills every day — runs on windows each payer sets in its own contract or dentist handbook, and those vary plan by plan.

For where this sits in the wider job, see what a dental billing coordinator does; this page stays on the deadlines.

The window depends on who the payer is.

Two rows are backed by public regulation; the third is set contract by contract:

Delta Dental's guidance to dentists on deltadentalins.com is the clearest worked example, because the same document shows both sides of the variation.

It tells dentists that, generally, claims received more than 12 months after the date of treatment may not be paid — and that some programs set shorter limits, giving the 90-day limit for the Texas CHIP program as its example.

Two windows in one guidance document — and the document that decides is the one that guidance points to: the dentist handbook for the specific plan.

Nor is the 12-month figure a Delta-wide rule: other Delta Dental member companies publish their own windows, which is exactly why the handbook for the specific plan is the thing to check.

That's the practical takeaway for every commercial payer, not just Delta.

The window is a contract term, not a public rule, so it isn't something to look up in a statute — it's written in the payer's provider manual or the participation agreement the practice signed, and a provider-relations rep can confirm it.

The reliable habit is capturing each payer's window once, at credentialing when the handbook arrives, rather than reconstructing it under pressure when a claim is already 11 months old.

Two kinds of state rule can touch a dental claim's deadline, and they work differently.

First, state Medicaid and CHIP programs.

The federal 12-month rule is an outer limit — it requires each state Medicaid agency to make providers submit claims within 12 months of the date of service, and a state's own program rules can set a shorter deadline.

Delta Dental's guidance to dentists on deltadentalins.com again supplies a concrete example: the 90-day limit it cites for the Texas CHIP program.

So the state a patient's public plan sits in can set a shorter deadline inside the federal 12-month limit.

Second, state insurance laws that regulate how fast claims must be submitted to health plans.

This is where an easy wrong answer lives: Texas has a 95-day claim-submission rule for preferred provider plans (Insurance Code 1301.102), but it does not apply to dental — Chapter 1301 states it does not apply to a provision for dental care benefits in a health insurance policy (Insurance Code 1301.002).

In the sources checked for this article, no state law setting a filing deadline specifically for commercial dental claims was verified.

The general lesson travels: before treating any state deadline as your rule, check whether the statute's scope actually covers dental benefits.

The original filing window isn't the only clock.

Once a claim comes back — denied as late, pended for more documentation, or paid at the wrong amount — corrected-claim and appeal deadlines come into play too.

This article doesn't pin any of those deadlines down: treat them as per-payer lookups the same way you treat the filing window, with the payer's provider manual the first place to check for its process and its deadlines.

Before assuming anything about why a line didn't pay, read the remittance advice closely — see reading an EOB for what each part of the document means.

One line shouldn't be crossed, and it's worth naming because the pressure to cross it is real.

When a claim has aged out of its window, changing the date of service so the claim lands back inside it is not a workaround: the ADA's Code of Ethics (5.B.4) calls reporting incorrect treatment dates on a claim to help a patient obtain benefits that would otherwise be disallowed an unethical, false or misleading representation.

The legitimate moves are narrower — appeal with documentation showing when the claim was actually submitted, or ask the payer what its late-claim and appeal process allows.

And where the pressure to bend a claim comes from an employer or a payer instruction rather than a missed deadline, see illegal billing practices for the lines billing staff shouldn't cross at all.

Practical habit: when you capture a payer's filing window, capture its corrected-claim and appeal deadlines in the same entry.

One lookup, one list, and all of that payer's clocks are in front of you the moment something comes back.

Every prevention habit comes back to one fact: the clock runs from the date of service, not from whenever the paperwork reached the claim.

A claim submitted the week of treatment has the whole window in front of it; a claim that sits in a work queue for months starts with most of it gone.

The habits that keep claims inside their windows:

• Capture the window when you capture the payer. At credentialing or plan onboarding, record the filing window — and the corrected-claim and appeal deadlines — from the provider manual.
• Verify coverage before the appointment. Eligibility, maximums, and frequency limits caught before treatment prevent the denial-and-resubmission cycle that burns window time later.
• Submit on a set cadence. Claims sent every day or two beat a month-end batch that surfaces problems after much of the window is already spent.
• Work the aging report against the clock. An unpaid claim aging toward its filing window is one of the highest-priority lines on the report — see AR and aging for the buckets and the follow-up workflow.
• Get the claim right the first time. A clean claim never re-enters the queue; a denied one ages while it's fixed and resubmitted.

That last point is where coding earns its place in the deadline conversation.

Dental claims run on CDT — the Code on Dental Procedures and Nomenclature — the standard code set required for dental services under HIPAA (45 CFR 162.1002), maintained and distributed by the American Dental Association.

It isn't static, either: the ADA's Code Maintenance Committee met on March 13, 2026 to agree on code changes for CDT 2027, so the set changes edition to edition and claims get coded from the current year's book.

See CDT codes for the code set in detail.

Who owns the calendar varies with the size of the practice.

In a smaller office, deadline tracking sits with whoever runs claims — which can mean one seat wearing both the front-desk and billing hats.

Where it's a dedicated job, it's the billing coordinator's core work.

BLS has no occupation for a billing coordinator; the nearest series it publishes, billing and posting clerks inside offices of dentists, counted 15,240 workers at a median of $24.96 an hour ($51,910 a year) in May 2025 — against $23.32 an hour ($48,500) for the same occupation across all industries.

On DentistryHires itself, as of October 22, 2026, there were 57 active dental billing and insurance coordinator listings; the 41 that stated an hourly rate had a median of $24.50 an hour, with the middle half between $21.50 and $27.50 — advertised pay rather than earnings, and a small sample.
