Bridging the Coverage Gap with Supplemental Plans

In a time where technology is evolving faster than we can sometimes keep up, standard dental benefits can feel stuck in the past, leaving a significant gap between the care our patients need and the care they can afford. Imagine that your doctor just finished a comprehensive evaluation on a patient who has not seen a dentist in quite some time. The patient is dealing with tooth pain and is being treatment planned for several dental procedures totaling around $2,500. Unsurprisingly, as soon as the patient sits down with the treatment coordinator, everything comes to a screeching halt. Before you even say “Good morning!” to the patient, they are already saying:

“I only want to do what my insurance will cover.”

The unfortunate truth is that a typical PPO dental plan has somewhere around a $1,500 maximum per benefit year, which won’t always cover it. A potential solution to help your patients pay for their treatment is a supplemental dental plan, which acts as a financial “bridge” that allows patients to move forward with the care they need without worrying as much about how or whether they can afford it.

But what is a supplemental dental plan?

Supplemental dental insurance is a dental plan that helps reduce a patient’s out-of-pocket costs. When we talk about supplemental dental insurance, we aren’t just talking about extra coverage; we’re talking about bridging the coverage gaps left by standard PPOs. These plans are specifically designed to pick up where primary insurance leaves off, covering high copays and services that are traditionally excluded.

For the patient, it’s a win because it slashes their out-of-pocket expenses, but these plans can also be a win for your practice, as well! For your practice:

• There is no need to worry about submitting documentation. A wonderful perk of supplemental dental plans is that they typically do not require supporting documentation. That means no more hunting for a specific radiograph or having to write lengthy and time-consuming narratives. Because they pay on a flat reimbursement schedule, the claims process is streamlined and predictable.
• The guesswork is all but eliminated. Standard dental insurance requires us to use estimation and percentages to work up treatment plans, whereas supplemental dental plans operate on a fixed fee schedule based on the specific plan the patient purchased. This results in clearer financial estimates given to the patient, and oftentimes faster claims processing, creating a more affordable way for a patient to pay for treatment.

Supplemental dental plans provide patients with a way to afford the treatment they need.

Understanding the structural differences between a standard PPO and a supplemental plan is a strategy for boosting case acceptance and getting patients treated. When patients rely solely on standard PPO plans, they are often tied to a baseline level of care. That means percentage-based coverage that hits an annual ceiling far too quickly, often backed by the administrative headache of needing to submit radiographs, periodontal charts, and detailed narratives just to get a claim considered for reimbursement.

While supplemental dental plans may offer lower out-of-pocket costs for major procedures like root canals, crowns, or orthodontics (if a benefit rider was purchased), keep in mind that, there may still be limitations in place (e.g. waiting periods). Thus, it is important to manage patient expectations regarding timing. While routine care might be covered immediately, they may have to wait anywhere from six months to a year before the plan begins to pay for more complex or expensive treatments.

All in all, by integrating supplemental dental plans into your financial discussions, you can provide the support necessary to turn a “I only want to do what my insurance will cover” into a scheduled appointment, helping to ensure that financial limitations no longer dictate clinical outcomes.
