What does this mean 100% coinsurance after deductible?

Having 100% coinsurance is anyone dream. After you have met your yearly deductible certain services are covered at 100%% and this means that you do not pay one penny towards the treatment. Your insurance company covers the entire bill so long as it is an agreed upon service that is considered essential by the insurer. Nov 13, 2018
