Dental Billing Services / KPI Field Guide

Gross collection lies. Net collection tells the truth.

For a solo-doctor PPO plus cosmetic practice, gross collection is dragged down by write-offs you agreed to the day you signed the PPO contract. Judge the office by the wrong number and you will chase revenue that was never collectible, while the revenue that leaked out the back stays invisible.

The short answer: Net collection, cash divided by production after contractual adjustments, is the real dental measure. Target 98 percent or higher. Anything lower is leakage you can recover: LEAT downgrade write-offs that were actually patient-billable, a denial trio that is roughly 78 percent preventable at the front desk, and medical cross-coding that most offices never bill at all.

Where a dollar of production actually goes

Follow one illustrative dollar from the chair to the bank. The PPO write-off is expected and contractual, so it belongs in the denominator, not the blame. The leakage bar is the part you get back.

Same cash, two very different scores

Gross collection rate

cash / gross production
= $565K / $1.00M

56.5%

Looks alarming. It is not, because $380K of that gap is a PPO contractual adjustment you agreed to. Gross rate punishes you for being in-network and tells you nothing you can act on.

Net (adjusted) collection rate

cash / (production - contractual)
= $565K / $620K

91.1%

The honest number, and it is under the 98 percent target. That 6.9 point gap is roughly $42,600 of recoverable cash sitting in LEAT write-offs, preventable denials, and unbilled medical claims.

Leakage Source 01 / LEAT Downgrades

LEAT leakage is often patient-billable, not a write-off

Under a Least Expensive Alternative Treatment clause and alternate-benefit downgrades, the plan pays as if you placed the cheaper material. That is the plan's business. Whether the patient owes the difference is yours, and if the predetermination set it up in writing, the difference is billable rather than adjusted off.

The downgrade the plan applies

Compositepaid asAmalgam

Porcelain crownpaid asMetal crown

The plan benefit is fixed at the alternate. The delta is not the plan's decision to erase.

What a predetermination unlocks

Run the predetermination first, document the LEAT reduction, and get the patient's informed financial consent before treatment. Then the downgraded portion is collected from the patient instead of written off. Skip that step and the same dollars vanish into contractual adjustments that were never contractual.

Leakage Source 02 / The Denial Trio

Three denials cause most of the pain, and they are front-end problems

Frequency limits

Prophy, bitewings, exams, or a crown replacement billed inside the plan's time window. The CDT code was correct; the calendar was not.

→

Prevent at scheduling

Verify last-service dates in the real-time eligibility response before the visit, and flag any code approaching its interval so the front desk sees it, not the biller a month later.

Missing attachment

Perio charting, periapical or bitewing images, or a narrative not sent with SRP, crowns, or surgical CDT lines. The claim is clean but naked.

→

Prevent at submission

Attachment rules by procedure category, enforced so the claim cannot leave the office without the documents the payer will demand anyway.

COB and missing-tooth clause

Wrong primary-secondary order, or a bridge or implant billed on a tooth the plan says was already missing before coverage began.

→

Prevent at intake

Capture full dual-coverage detail and prior-extraction history at registration, and screen the missing-tooth clause during the predetermination, not after the lab bill is paid.

Leakage Source 03 / Found Money

Medical cross-coding: revenue most dental offices never claim

Many procedures a cosmetic and PPO practice performs are medically billable. Cross-coding from CDT to CPT and ICD-10 sends the claim to the patient's medical plan, where the fee schedule and the benefit are often stronger than dental. This is net-new cash, not a shuffle.

CDT → CPT / ICD-10Oral surgerySurgical extractions and pathology-driven removals routinely qualify under medical.

CDT → CPT / ICD-10Implants and bone graftsRidge preservation and grafting tied to trauma or disease can carry a medical claim.

CDT → CPT / ICD-10BiopsiesSoft and hard tissue biopsies are a natural medical crossover with a diagnosis code.

CDT → CPT / ICD-10Sleep-apnea appliancesOral appliance therapy for diagnosed OSA is a medical benefit, not a dental one.

CDT → CPT / ICD-10TMJDiagnosis, imaging, and appliance therapy for TMJ disorders belong on the medical side.

The catchIt needs both code booksYou cross-code correctly or the medical payer denies it. This is exactly where a specialist RCM partner earns the fee.

What this adds up to

Watch net collection, not gross. Hold it at 98 percent or higher. Convert LEAT downgrades into patient responsibility with a predetermination and signed financial consent instead of writing them off. Stop the denial trio at the front desk where roughly 78 percent of it is preventable. And bill the medical claim that a dental-only office leaves on the table every week. In the illustrative model above, closing that gap on $1,000,000 of production recovers about $42,600 of cash the office already produced and simply did not keep. Real practices vary; the discipline does not.
