Cigna has announced a new shared network agreement with Guardian that takes effect on August 1, 2026. This change may affect how Guardian claims are processed and reimbursed for dental practices that participate with Cigna. Whether this agreement impacts your office depends on your current participation status with both Cigna and Guardian.

Cigna–Guardian Shared Network Agreement (Effective August 1, 2026)
Overview
Cigna has announced a new shared network agreement with Guardian that takes effect on August 1, 2026. This change may affect how Guardian claims are processed and reimbursed for dental practices that participate with Cigna.
Whether this agreement impacts your office depends on your current participation status with both Cigna and Guardian.
Scenario 1: You Have a Direct Cigna Contract and Are Out-of-Network with Guardian
If your practice currently:
Has a direct contract with Cigna, and
Is out-of-network with Guardian
then Guardian members may automatically become in-network under your existing Cigna fee schedule through this new agreement.
Important: Automatic Enrollment
Practices should assume they will be automatically opted in unless they take action to opt out.
If you are comfortable with Guardian utilizing your Cigna fee schedule:
No action is required.
No new paperwork needs to be completed.
If you do not want Guardian to access your Cigna contracted fees:
You must actively opt out of the agreement.
How to Opt Out
According to the announcement, practices can opt out by emailing Cigna's provider service team.
Scenario 2: You Have Direct Contracts with Both Cigna and Guardian
If your practice already maintains:
A direct contract with Cigna, and
A direct contract with Guardian
then this new shared network arrangement should not change your reimbursement structure.
What Happens?
Cigna claims will continue to process under your direct Cigna contract.
Guardian claims will continue to process under your direct Guardian contract.
Direct contracts take precedence over shared network arrangements.
Scenario 3: You Have a Direct Cigna Contract and Access Guardian Through Another Network
Many practices participate with Guardian through a third-party network rather than a direct Guardian agreement.
Examples include:
Connection Dental
Carrington
UnitedHealthcare Dental
Other leased or shared networks
Potential Impact
In this situation, Guardian may choose to stop using your current network pathway and instead reimburse under your Cigna fee schedule.
This can be significant if:
Your current Guardian reimbursement rates are higher than your Cigna rates.
Example
If:
Your Cigna fee schedule is relatively low, and
Guardian currently pays you through a higher-paying network such as Connection Dental or Carrington,
then Guardian could potentially begin paying based on the lower Cigna fee schedule after this agreement takes effect.
When to Consider Opting Out
You may want to evaluate opting out if:
Your Cigna fees are lower than the fees you currently receive through another Guardian network arrangement.
The change would result in reduced reimbursement.
If your Cigna fees are already higher than your current Guardian pathway, this may be less of a concern.
Understanding Cigna Shared Network Opt-Out Rules
One important consideration is that Cigna's shared network participation is generally an all-or-nothing arrangement.
What This Means
If you opt out:
You are not just opting out of the new Guardian agreement.
You are opting out of Cigna's shared network program as a whole.
Consider Other Shared Network Relationships
Before opting out, practices should review whether they currently benefit from any other Cigna shared network arrangements.
An opt-out could affect participation with additional carriers that access your practice through Cigna's network-sharing agreements.
Who Is Affected?
This announcement primarily applies to practices that have a direct Cigna contract.
If your practice participates with Cigna through another network and does not have a direct contract with Cigna, this particular agreement generally would not apply to your situation.
Recommended Next Steps
Review Your Current Participation Structure
Determine:
Do you have a direct Cigna contract?
Do you have a direct Guardian contract?
Are you accessing Guardian through another network?
Compare Fee Schedules
Evaluate:
Current Guardian reimbursement rates
Cigna contracted rates
Potential financial impact if Guardian begins using the Cigna fee schedule
Decide Whether to Opt Out
If the new arrangement could reduce reimbursement, consider whether opting out of Cigna's shared network program is appropriate for your practice.
Document Your Decision
Given the automatic participation assumption, practices that wish to opt out should take action before the effective date.
Key Takeaway
The new Cigna–Guardian shared network agreement may create additional in-network access for Guardian members under existing Cigna contracts. For some practices, this may have little or no impact. For others—particularly those receiving higher Guardian reimbursement through third-party networks—it could result in lower payments if Guardian begins reimbursing under Cigna fee schedules.
The most important step is to understand how your practice currently participates with both carriers and compare fee schedules before deciding whether to remain in or opt out of the arrangement.
