"Are you a preferred provider?" is one of the most common questions new patients ask a dental practice. Health fund networks, also called preferred provider or partner networks, promise members lower or no out-of-pocket costs at participating practices, in return for practices agreeing to the fund's fees or conditions. With funds such as nib changing how they pay benefits outside their networks, more practice owners are asking whether to join.
This guide explains how health fund dental networks work, what "no-gap" and "known-gap" mean, and the pros and cons of joining.
This article is general information, not financial or legal advice. Every fund's contract is different. Read it carefully and get advice before signing.
Key takeaways
- In a preferred provider network, a practice agrees to the fund's terms, often a fee schedule or price caps, and the fund pays its members higher benefits or covers the full cost of some services.
- No-gap means the member pays nothing for certain services; known-gap means the member's out-of-pocket cost is set in advance.
- Joining can bring more patients and easier conversations about cost, but may mean lower fees and less control.
- Some funds pay less to members who see non-network practices. nib, for example, changed how it pays benefits outside its First Choice network from 1 October 2026.
- Model the numbers for your own practice before deciding.
How dental networks work
Private health insurers can make arrangements with dental practices for services covered by extras policies. Typically:
- The practice signs an agreement with the fund.
- The agreement sets fees, price caps or other conditions for some or all services.
- Fund members get higher benefits, a no-gap or known-gap price, or both, at network practices.
- The fund may promote network practices to members, for example in its "find a provider" tool.
Not every fund runs a network. Some pay the same benefits wherever members go.
The ACCC and price caps
Arrangements between insurers and competing practices about prices can raise competition law issues, so some need authorisation from the Australian Competition and Consumer Commission (ACCC). For example, the ACCC authorised St Luke's Health to make price-capping agreements with dentists in its partner network, with the aim of offering no-gap or known-gap services. The authorisation runs until November 2029.
The Australian Dental Association has long raised concerns about differential rebates, where members with the same policy get different benefits depending on which practice they visit.
Potential benefits of joining
- New patients: funds may direct members to network practices.
- Retention: existing patients with that fund are less likely to move to a network practice.
- Simpler cost conversations: "no gap for your check-up and clean" is easy to explain.
- Predictable billing for covered services.
Potential drawbacks
- Lower fees for some services than your usual schedule.
- Less control over pricing and sometimes over how services are delivered or claimed.
- Administration: different rules for different funds can complicate the front desk.
- Contract terms: audits, reporting, termination clauses and fee reviews controlled by the fund.
- Patient mix: a high share of network patients can make a practice dependent on one fund's decisions.
How to decide
1. Know your patient mix
From your practice software, find out what share of patients are with each fund, and what those patients spend each year.
2. Model the fees
Compare the fund's fee schedule with your current fees for your most common item numbers. Multiply by your volumes to estimate revenue under both scenarios.
3. Estimate the patient impact
How many new patients might the network bring, and how many existing patients might you lose if you don't join? Be conservative.
4. Read the contract
Check fees, review periods, audit rights, marketing commitments, exit terms and any exclusivity.
5. Talk to peers and advisers
Your accountant, the ADA and other practice owners can help you sense-check the decision.
Explaining it to patients
Whichever you choose, your front desk needs clear, accurate wording.
If you're in the network:
"Yes, we're a [fund] network provider, so many members pay no gap for check-ups and cleans, depending on their level of cover."
If you're not:
"We're not a network provider for [fund], but you can still claim with us on the spot through HICAPS. We can give you the item numbers and our fees so you can check exactly what you'll get back."
Avoid promising "no gap" unless you can guarantee it for that patient and service, and remember that pricing claims are subject to Ahpra's advertising rules. See Ahpra advertising rules.
Making fund questions easier
Health fund questions are some of the most frequent calls a practice gets. Standard answers on your website, in your phone script and in your AI receptionist's knowledge base save time and give patients consistent information. See cutting admin time on health fund enquiries and what nib's October 2026 change means for practices.
Frequently asked questions
Does joining a network guarantee more patients?
No. It can help, especially where many local patients are with that fund, but results vary.
Can I join more than one fund's network?
Often yes, subject to each contract. Managing several sets of rules adds complexity.
Can I leave a network?
Most contracts allow it with notice. Check the terms before you join, and plan how you'll tell affected patients.
