Would you be concerned if your local hospital left your insurance network?
Hillcrest Healthcare System is now out of network with Aetna for all Aetna insurance plans after its agreement expired on November 1, 2026. Hillcrest's facilities and employed providers are affected, so Oklahoma patients covered by Aetna may face new out-of-network costs.
Why it matters
Hillcrest cites below-market reimbursement rates and payment practices as ongoing concerns, and says Aetna leadership has refused to engage with its leadership. For healthcare operators and the businesses that rely on these providers, the lapse shows how payer-provider contract disputes can cut off access to a major network.
The agreement expired on November 1, 2026, and Hillcrest attempted to reach Aetna leadership multiple times over the past six months. The source does not provide reimbursement rates, patient counts, or the number of facilities affected.
The players

The details
Hillcrest's agreement with Aetna expired, which places its facilities and employed providers out of network for all Aetna insurance plans. Emergency services continue to be covered at in-network benefit levels, and some Aetna patients may qualify for continuity of care protections. Patients with questions about those protections should contact Aetna using the phone number on the back of their insurance card.

Market Landscape
The Hillcrest-Aetna lapse follows the pattern of payer-provider contract disputes, in which a provider system and insurer fail to renew terms and services go out of network. Hillcrest's stated concerns about below-market reimbursement place the dispute within broader arguments over payment rates between health systems and insurers.
Oklahoma operators with employees on Aetna plans should check whether their staff use Hillcrest providers and plan for out-of-network costs. Benefits and HR teams should review continuity of care options with their carriers.
The takeaway
Operators with Aetna-covered employees should confirm which local providers remain in network and watch for any renewed Hillcrest-Aetna agreement. Benefits managers should document the out-of-network change for employees before the next enrollment period.
