What is the dental billing process?

It's the cycle that gets a practice paid for treatment. Verify the patient's insurance before the visit, code the treatment and check documentation, submit the claim, let the payer adjudicate and issue an EOB, post the insurance payment, work any denial, bill the patient for the remainder, and follow up on aging accounts receivable until the claim is closed.

What is the difference between dental billing and dental coding?

Coding is assigning the correct CDT code to each procedure. Billing is the larger process that uses those codes to get the claim paid, from verification through AR follow-up. Coding is one step inside billing. A wrong code causes a denial, which is why the two are tightly linked, but they are not the same job.

What is a clean claim?

A claim with everything the payer needs to adjudicate it on the first pass: correct subscriber and provider IDs, accurate CDT codes, the required attachments (pre-op X-rays, narratives, perio charting), and no missing fields. Clean claims get paid faster and denied less. Most denials trace back to something that made the claim not clean before it left the office.

How long does it take to get a dental claim paid?

For a clean electronic claim, commonly two to four weeks, though it varies by payer. Paper claims and claims that need attachments take longer. A denied claim resets the clock, which is why working denials the day they arrive matters. Every payer also has a timely filing limit, often 90 days to a year from the date of service, after which the claim can't be filed at all.

What is the difference between an EOB and an ERA?

Both report how the payer adjudicated a claim. An EOB (explanation of benefits) is the human-readable version, on paper or as a PDF. An ERA (electronic remittance advice, the HIPAA 835 transaction) is the electronic version that posts into your practice management software automatically. They carry the same information: what was allowed, what the plan paid, the contractual adjustment, and what the patient owes.

Can a dental practice outsource billing?

Yes. A billing company can run any part of the cycle, from insurance verification through AR recovery, working inside your existing practice management software. Practices outsource when in-house billing can't keep up with claim volume, when denials and AR are piling up, or when turnover keeps leaving the role unfilled. You keep clinical control; the billing team handles claims, payments, and follow-up.

What Is Dental Billing? The Process, Step by Step

Dental billing is the process of getting a practice paid for the treatment it provides. It runs from verifying a patient’s insurance before the visit, through submitting the claim and posting the insurer’s payment, to working any denial and collecting whatever the patient owes. When people say “the dental billing process,” this full cycle is what they mean.

This guide walks the cycle one step at a time. It’s written for the person who owns the practice or runs the front office and wants to understand what happens to a claim after a patient leaves the chair, and where the money tends to fall through the cracks.

The dental billing process, step by step

Every paid claim travels the same path. Some steps happen before the patient ever sits down. Most of the work, and most of the lost revenue, lives in the steps after the claim is submitted.

01 Verify insurance eligibility and benefits before the visit
02 Code the treatment and check the documentation
03 Submit the claim (usually an electronic 837D)
04 The payer adjudicates and issues an EOB or ERA
05 Post the insurance payment and the contractual adjustment
06 Work any denial: pull the EOB, correct or appeal
07 Bill the patient for the remaining balance
08 Follow up on aging AR until the claim is paid

The rest of this guide takes each step in turn.

Insurance verification comes first

Verification happens before the appointment, not after. The goal is to know, before the patient is in the chair, what the plan covers, what the deductible and remaining maximum are, and which procedures carry frequency limits or waiting periods.

When verification is skipped or done at the front desk while the patient waits, the practice ends up quoting wrong estimates, collecting too little, and chasing balances later. A clean verification feeds an accurate treatment estimate, which is the difference between collecting at the visit and sending a statement two months out.

For the full list of what to check, see our insurance verification checklist.

Coding and documentation

Each procedure gets a CDT code, the standardized dental procedure codes the American Dental Association maintains and updates every year. The code has to match what was done and what the clinical record supports.

Documentation is the other half. A crown claim needs the pre-op X-ray. A scaling and root planing claim needs perio charting that supports the diagnosis. A surgical extraction needs a narrative. Missing the attachment is one of the most common reasons a claim comes back denied, and it’s avoidable at this stage. Our CDT code reference explains what individual codes mean and what payers expect with them.

Submitting the claim

Almost every claim today ships electronically as an 837D, the HIPAA-standard electronic dental claim, sent through a clearinghouse to the payer. A small number still go on the paper ADA Dental Claim Form, usually for predeterminations or attachment-heavy cases.

Adjudication: what the payer does with the claim

Once the claim arrives, the payer adjudicates it. It checks eligibility on the date of service, applies the plan’s coverage rules (coinsurance, deductible, frequency limits, downgrades), and decides what it will pay.

The result comes back as an explanation of benefits (EOB) or its electronic equivalent, an electronic remittance advice (ERA). That document tells you the allowed amount, what the plan paid, the contractual adjustment, and what the patient owes. Everything downstream depends on reading it correctly.

Posting payments and reading the EOB

Posting is where the EOB gets recorded against the claim in your practice management software. The insurance payment posts, the contractual write-off posts (for in-network claims, the difference between your office fee and the allowed amount), and the patient balance is whatever remains.

This is also where dual coverage gets handled. When a patient has two plans, you wait for the primary to pay, then send the secondary with the primary’s EOB attached, and you hold the write-off until both have processed. Posting the write-off too early on a dual-coverage claim is one of the quietest ways practices lose money. We cover the full sequence in primary vs. secondary dental insurance.

Denials and appeals

Some claims come back denied or underpaid. A denial is not the end of the claim; it’s a queue that has to be worked.

The work is the same each time. Pull the EOB, read the reason code, and either correct and resubmit (wrong tooth number, missing attachment) or write an appeal with documentation (medical necessity, frequency override). A denial worked the day it lands gets resolved inside the filing window. A denial that sits for three weeks often ages out.

Billing the patient

After insurance has processed, the patient owes whatever’s left: the deductible, the coinsurance, and anything the plan didn’t cover. The statement should go out promptly and reflect the real balance after all plans have paid.

Sending the patient statement before the secondary pays, or before a denial is resolved, produces wrong balances, confused patients, and refund requests. Wait until the claim is fully adjudicated, then bill the actual number.

Accounts receivable follow-up

Accounts receivable (AR) is the money owed to the practice that hasn’t come in yet, from both insurers and patients. AR is tracked in aging buckets: 0 to 30 days, 31 to 60, 61 to 90, and 90 plus. The older a balance gets, the harder it is to collect.

Follow-up means working the report on a schedule: calling on unpaid insurance claims, re-sending patient statements, and escalating the oldest balances before they become uncollectible. AR that nobody works on a regular cadence is where a practice’s collections silently fall behind production. If your AR over 90 days is growing, that’s the signal. Our AR cleanup service exists for exactly that backlog.

Dental billing vs. dental coding

These get used as if they’re the same thing. They aren’t. Coding is assigning the right CDT code to each procedure. Billing is the whole cycle above, which uses those codes to get paid. Coding is one step inside billing.

The reason they blur together is that a coding error causes a billing problem. A wrong or unsupported code is a denial, and the denial lands back in the billing workflow. Good billing depends on good coding, but billing keeps going long after the code is assigned.

In-house vs. outsourced billing

Many practices run billing in-house, often as one role on the front desk. That works until claim volume outgrows the time available, or the role turns over, or denials and AR start stacking up faster than one person can clear them.

Outsourced billing moves the cycle to a dedicated team that works inside your existing software. The practice keeps clinical and scheduling control; the billing team handles verification, claims, posting, denials, and AR follow-up on a daily cadence.
