Dental RCM Glossary.

Confirming a patient's active coverage, benefit levels, and plan limits before an appointment. Done well, it is the single largest lever on downstream denials — most eligibility-related denials trace back to something that could have been checked before the patient sat down.

A detailed read of maximums, deductibles, coinsurance, frequencies, and waiting periods for the patient's plan. A full breakdown goes well beyond "active/inactive" — it is what makes an accurate treatment estimate possible.

The most a dental plan will pay toward covered services in a benefit year. Once it is exhausted, the remaining balance becomes patient responsibility. Tracking the remaining maximum mid-year is essential for accurate estimates on large treatment plans.

The amount a patient pays out of pocket before the plan begins paying. Often waived on preventive services, and often reset each benefit year. Family plans may carry a separate, larger family deductible.

The percentage split between plan and patient once the deductible is met — commonly 100% preventive, 80% basic, 50% major. The percentage applies to the plan's allowed fee, not the practice's full fee, which is why patient portions surprise people.

A flat dollar amount the patient owes for a specific service, typical of DHMO and capitation plans. Unlike coinsurance, it does not vary with the fee charged.

A span after enrollment during which certain services are not covered — frequently 6 months for basic and 12 months for major services. A patient can be fully "active" and still have no coverage for the procedure being planned.

A plan rule capping how often a procedure is covered — two cleanings per calendar year, one complete series every three to five years, one exam per six months. Frequency is measured either per calendar year or from the last date of service, and the distinction changes the answer.

A provision excluding coverage for replacing teeth that were already missing before the plan took effect. A common and expensive surprise on bridges, partials, and implants.

Least Expensive Alternative Treatment — the payer pays for a cheaper clinically acceptable option than the one performed. The classic case is a posterior composite reimbursed at the amalgam fee. The procedure is covered; it is just paid at a lower rate, and the difference lands on the patient.

The rules determining how two or more plans share the cost when a patient has multiple coverages, and in what order they pay. Getting COB wrong is one of the most common causes of an underpayment that surfaces weeks later.

The primary plan pays first against its own schedule; the secondary considers the balance under its rules, which may be non-duplicating rather than true "wraparound" coverage. Secondary rarely pays whatever the primary left.

The convention used to decide which parent's plan is primary for a dependent child: whichever parent's birthday falls earlier in the calendar year, regardless of age.

Whether the provider has a contract with the payer. In-network providers accept a negotiated fee schedule and write off the difference; out-of-network reimbursement is based on the plan's allowed amount and the balance may be billable to the patient.

The contracted amount a payer allows for each procedure code with a participating provider. It, not the practice's standard fee, is the basis for every calculation the plan makes.

The payer's determination of a typical fee for a procedure in a geographic area, used to cap out-of-network reimbursement. UCR tables are set by the payer and are not published to practices in most cases.

Submitting a proposed treatment plan to the payer for a written estimate of coverage before treatment. A pre-determination is an estimate, not a payment guarantee — eligibility must still be active on the date of service.

The dates a patient's coverage begins and ends. Coverage is determined on the date of service, so a plan that is active today may not have been active at the appointment being billed.

Whether maximums, deductibles, and frequencies reset on January 1 or on the plan's own anniversary date. Assuming calendar year on a plan-year policy produces wrong remaining-maximum figures all year.

A claim with no errors or missing data, accepted by the payer on first submission. Clean claims are paid faster and cost dramatically less to work than claims that need rework.

The share of claims accepted without rework — a core measure of billing health, and a more honest one than raw collections, because it isolates process quality from volume.

Current Dental Terminology — the ADA-maintained procedure code set used on every dental claim, updated annually. Codes are structured by category (D0000 diagnostic, D1000 preventive, D2000 restorative, and so on).

Checking a claim against payer rules, plan limits, and documentation requirements before submission, so errors are caught in the practice rather than discovered as a denial weeks later.

The written clinical justification attached to a claim explaining why a procedure was necessary. Frequently required on crowns, periodontal therapy, and anything a payer might consider elective.

Supporting documentation submitted with a claim — radiographs, periodontal charting, intraoral photos, or a narrative. Missing attachments are among the most common and most avoidable causes of denial.

An intermediary that receives claims from the practice, validates format, and routes them to the correct payer electronically — translating between the practice's system and each payer's requirements.

The standard HIPAA electronic transaction formats: 837 submits a claim, 835 returns the remittance, 270 asks an eligibility question, and 271 returns the eligibility answer. The 270/271 pair is fast but often returns thinner benefit detail than a portal or a call.

The unique identifier that routes an electronic claim to a specific payer through a clearinghouse. The same insurer can have different payer IDs for different products or regions.

National Provider Identifier — the ten-digit federal ID for providers and organizations. Claims typically carry both a rendering provider NPI (Type 1) and a billing entity NPI (Type 2).

The deadline for submitting a claim after the date of service, commonly 90 days to 12 months depending on payer and contract. Miss it and the claim is unrecoverable — the balance usually cannot be billed to the patient either.

A rejection never entered adjudication — it failed a format or data check at the clearinghouse or payer front door, and can be corrected and resubmitted. A denial was adjudicated and refused. The distinction matters because it decides whether you fix and resend or appeal.

The payer's process of evaluating a claim against the patient's plan to decide what, if anything, it pays.

Claim Adjustment Reason Codes and Remittance Advice Remark Codes — the standardized codes on a remittance explaining why an amount was adjusted or denied. Reading them correctly is what separates a targeted appeal from a blind resubmission.

A formal request for the payer to reconsider a denial, usually with additional documentation. Payers set their own appeal windows and levels, and the window is often shorter than the original filing limit.

A payer combining two separately billed procedures into one reimbursement, on the basis that one is considered part of the other. Common on surgical and periodontal codes.

The payer processed the claim and paid less than the contracted fee schedule or the plan's stated benefit. Underpayments are systematically under-detected because the claim technically "paid" and stops drawing attention.

Electronic Remittance Advice / Explanation of Benefits — how payers report what they paid and why. The ERA is the machine-readable version that drives automated payment posting; the EOB is the human-readable equivalent.

Applying payer payments and adjustments to the correct patient ledgers and claims. Slow or inaccurate posting distorts every AR number downstream and hides underpayments.

Outstanding balances bucketed by age — 0–30, 31–60, 61–90, and 90+ days. Collectability drops sharply as balances age, which is why the 90+ bucket is the one that quietly becomes bad debt.

A reduction to a balance. Contractual adjustments are the negotiated difference between full fee and allowed fee for in-network care. Discretionary write-offs are revenue the practice chose, or failed, to collect — and the two should never be tracked in the same bucket.

The portion of the bill the patient owes after the plan pays — deductible, coinsurance, copay, amounts over the annual maximum, and non-covered services.

An amount still owed by the patient when they leave the appointment. The longer it goes unworked, the less likely it is ever collected, which is why same-day outreach materially outperforms a monthly statement run.

Payments collected as a percentage of what was actually collectible after contractual adjustments. It answers "did we collect what we were owed," which gross collection rate does not.

A payer paying more than it should have and later requesting the difference back, often by offsetting future payments rather than invoicing. Unreconciled offsets are a frequent source of AR that will not tie out.

The system of record for scheduling, clinical notes, and the patient ledger — Dentrix, Eaglesoft, Open Dental, Denticon, CareStack, Curve, Cloud9 and others. Some are cloud-hosted, many are still installed on a server in the practice, and that difference determines what a vendor can integrate with.

Everything between booking an appointment and the last dollar collected: verification, treatment estimate, claim submission, payment posting, denial work, and patient balance resolution.

Returning verified data or claim status directly into the practice management system, no re-keying. Without write-back, an automated verification is just a document someone still has to transcribe — which is where the time savings quietly disappear.

The web application a payer provides for eligibility and claim status lookups. Coverage and depth vary enormously by payer, and portals go down, change layout, and omit fields that only a phone call will surface.

Interactive Voice Response — the automated phone tree standing between a verification specialist and a payer representative. IVR navigation and hold time, not the conversation itself, consume most of the minutes on a verification call.

Robotic Process Automation — software that reproduces the exact clicks and keystrokes a person would perform. Fast and reliable on stable screens, brittle when a portal changes, and unable to reason about an unexpected case.

Automation where software agents pursue a goal, choose among methods, and adapt when one path fails — rather than replaying a fixed script. In verification this is the difference between a bot that stalls on a broken portal and an agent that places a call instead.

A workflow where AI does the volume and specialists review edge cases for accuracy. It is what keeps automation rates high without accepting black-box risk on the cases that need judgment.
