@teelea68 Contact Cigna and request a Member Advocate, Health Advocate, etc. If it's an available benefit, they can call on your behalf to find an INN provider.
Otherwise, call Cigna and ask for the details of their network adequacy requirement is for your plan type.
They have to have a certain number of providers available in your area who can see you within a reasonable amount of time at your INN cost-share amounts. If they do not have sufficient providers for a covered service within their mandated radius that are accepting patients, request a network adequacy exception and see any provider that is willing to take you - your insurer will work out the details.
You may have to call around, but they can't control when providers are and are not updating their status in a timely manner unless it's reported. Honestly, fax may also be an option. For large healthcare provider groups, you may be able to check on a myChart or equivalent en masse.
You may be able to jump this by filing a General Complaint for incorrect directory information with Cigna, you may have to do this by writing. Compliance folks tend to be linked in with resolution teams and network management and this is a compliance issue. Your plan documents will advise you of how to handle it.
You can still get care, you've just gotta work within the system.
