Dental Insurance Insights: 10 Member Questions Answered

Insurance and coding questions tend to fall into recognizable patterns. When those patterns are understood, the solutions become far more predictable. During a recent Office Hour session, we walked through member questions involving hybrid cases, recoupments, secondary insurance, network changes and more.

If you weren’t able to attend the live office hour, here’s what you missed:

Below are ten questions that were asked during the session, along with clear, succinct steps to address them. You can also watch the recording to hear the complete answers and discussion and earn one CE credit.

1) "Our negotiated fee increases were only 3%—and a few codes even went down. How do we actually raise low insurance fees?"

Short answer: Stop letting payers define the terms. If you’re still directly contracted with most carriers, you’re likely stuck at the bottom. Offices see far larger improvements by using umbrella/leased networks (e.g., Carrington, Zelis, Connection, etc.) and a competent negotiator.

What to do:

• Audit your effective discounts. If your overall discount is ~50–60%, that’s a red flag—there’s room to improve while staying in‑network through umbrellas.
• Beware the “3% raise” trap. Some carriers quietly lower high‑volume diagnostic codes while raising many you rarely use—netting no real increase.
• Leverage indirect contracts. Offices frequently achieve 20–50% improvements by moving under umbrellas and negotiating correctly.
• Delta is the exception. They don’t participate with umbrellas. The long‑term play is improving other payer fees high enough that dropping Delta becomes feasible.

2) “Insurance approved and paid a claim—then months later requested a refund. Can we fight the recoupment?”

Short answer: Sometimes. It depends on state recoupment limits, ERISA, and reason. Prevention is best.

Key points:

• Know your state’s recoupment timeline. Some states are ~180 days (e.g., TX); many are 1–2 years. If the payer is outside the state limit and not ERISA, dispute it.
• ERISA plans often claim state laws don’t apply; you can still send dispute letters, but success varies.
• Fraud exceptions: No time limit if there’s evidence of fraud (e.g., wrong x‑ray, altered dates).

Prevention that works:

• Ask about employment status upfront. If a patient recently lost a job or coverage may end, collect from the patient and have insurance pay them, not you—recouping from a patient is far less likely than from a provider.
• If within the time limit and valid, repay quickly to avoid accounting headaches.
• Use clear internal scripts to check coverage timing before treatment starts.

3) “A patient was FFS when scheduled. On the treatment day they have new insurance (with a waiting period), we’re in‑network, and then they cancel the plan after. Are we stuck honoring the discounted fee?”

Short answer: You’ll often need to honor in‑network discounts for covered services (even if not payable due to a waiting period). But many components of large cases are non‑covered or internal—those are full fee.

What to align:

• Covered vs. non‑covered: Waiting periods make services not payable—but still covered under the plan design, which triggers in‑network discounts.
• Non‑covered is different: Items never covered (e.g., nitrous, many CBCTs, adult fluoride, certain cosmetic elements) are full fee with no INN discount.
• Keep discounts reasonable overall. If your INN discounts are extreme (e.g., 50–60%), fix the fee schedule problem first. Membership plan discounts (often ~10–20%) help normalize expectations.

4) “Hybrid denture cases: How should we code and structure these so they’re compliant and make financial sense?”

Short answer: Treat every step (surgical and prosthetic) as its own line item with the correct CDT or internal code. Hybrids are complex, and most of the value lies outside the single “hybrid” code.

Core principles:

• Diagnostics:
• Diagnostic casts ≠ wax‑ups. Casts have an ADA code; wax‑ups require an internal code.
• Many diagnostics (e.g., CBCTs) are non‑covered → full fee.
• Surgical & prosthetic:
• Extractions, alveoloplasty, placements, conversion, attachments, and the final prosthesis each have codes.
• The “hybrid” code (e.g., D6114/D6115) is only one piece of the work.
• Covered vs. sometimes covered vs. non‑covered: Expect a mixed treatment plan.
• Set your fees line‑by‑line (cash and insurance consistently) and then bundle ethically if that’s your model (see Q5).

5) “For large/bundled cases, do we itemize or submit a package? What about discrimination and write‑offs?”

Short answer: Be consistent. Bill and code the same way you would for a cash patient. Discrimination occurs when similar patients are charged differently without a clinical reason.

Guidelines:

• Submit covered services (INN contracts often require this). Don’t submit internal codes. Avoid sending non‑covered items unless required—many payers ask you not to because their systems mishandle them.
• Write‑offs apply to covered services that would be payable under the plan (now or in future). Non‑covered and internal items: no write‑off.
• Bundled discount strategy: You can ethically offer a bundled/prepay discount (off your full, itemized structure) as long as:
• You’d offer the same structure/discount to cash patients
• The final amounts don’t dip below your contractual INN fee for covered items
• You’re consistent across patients (no favoritism)

Tip: For patients who will max out anyway, some practices offer an “insurance maximum discount” to not involve insurance on the rest—reduces admin time and can increase acceptance (stay compliant with INN floors).

6) “Secondary insurance: Should we file? How do we estimate—and what about write‑offs?”

Short answer: Yes, file it. It takes little time and increases patient trust. Estimate $0 from secondary to avoid over‑promising, then let the EOB decide.

Best practices:

• Always submit full office fees (see Q9)—secondary can pay above your INN fee depending on coordination of benefits.
• Attach the primary EOB and send the secondary claim.
• Ignore suggested write‑offs on EOBs when secondary is involved; they’re often wrong. Calculate based on your fee schedule and the plan’s COB rules.
• Use a secondary calculator (if you have one in your toolkit) to speed the math and reduce over‑adjustments.

7) “Delta/Blue Cross won’t honor assignment of benefits (AOB), so checks go to patients. How do we protect collections?”

Short answer: Don’t chase checks. Use state AOB laws if applicable and otherwise set clean payment workflows.

Options that work:

• Check your state AOB law. If your state requires AOB to the provider (and it’s not ERISA), cite it.
• Credit card authorization model:
• Collect copay today.
• 30 days after expected payer date, auto‑charge the remaining balance. The patient should have received and deposited the check by then.
• Avoid asking patients to mail you the check. It’s unreliable and time‑consuming for your team.
• Long‑term: Encourage employers (via patients/HR) to push carriers to send benefits to the office—this can be negotiated at the employer‑plan level.

8) “Non‑covered services (night guards, nitrous, adult fluoride, retainers): Do we submit—and do INN discounts apply?”

Short answer: For non‑covered items: no required INN discount and generally do not submit. Charge your full fee and provide patients with an itemized ledger (usually all HSAs/FSAs need).

Patient communication:

• Tell patients upfront: “This won’t appear on your EOB because it’s not covered.”
• If an FSA/HSA specifically demands an EOB (rare), you may send a separate, informational claim only if needed—but most plans accept a ledger.

9) “Imaging: Are single bitewings ever smart? And what about the ADA ‘update’ and Principal’s PA policy?”

Short answer: For emergencies, take four bitewings instead of one—prevents frequency problems later and improves diagnosis. A pre‑cement bitewing for a crown is part of the crown (not separately billable).

On “updated” radiograph guidance:

• The ADA’s routine x‑ray guidance hasn’t materially changed since 2012; Principal is the payer making this an issue by asking for documentation when >2 PAs are submitted.
• Practical move: Maintain good narrative templates (a dozen or fewer cover most scenarios). If requested, submit why each PA was necessary.

10) “We keep getting EOBs wrong—coinsurance, downgrades, ‘not payable’ lines. How do we stop over‑adjusting?”

Short answer: Distinguish coinsurance (patient share of what the payer allowed) from the patient’s total responsibility. With out‑of‑network, the patient owes your full fee minus what insurance paid (no write‑off). With in‑network, write off according to your fee schedule, not the EOB guess.

How to read it:

• Coinsurance ≠ total patient portion. It’s only a percentage of the allowed amount, not your submitted fee.
• “Not payable” often means not covered by the plan (still patient responsibility), not an office write‑off.
• Downgrades: The payer pays on a lesser code; the difference is typically patient responsibility (per plan rules).
• Build a team habit of reading the legend/remarks on every EOB. Formats vary, but the principles don’t.

Summary

Insurance questions may look different on the surface, but the underlying principles rarely change. When teams understand how coverage works, how to read EOBs correctly, and how to structure fees and coding consistently, most of these challenges become far easier to manage.

The goal is not to memorize exceptions, it’s to build systems that make the right answer predictable. If your team can apply the approaches in these ten scenarios, you’ll find that many similar issues resolve more smoothly and with far less stress.
