Long term care insurance is designed to provide coverage for individuals who need assistance with activities of daily living (ADLs) or have cognitive impairments. The age at which you can purchase long term care insurance varies depending on the insurance company and the policy. While there is no specific age limit to buy long term care insurance, it is generally recommended to purchase it before the age of 65. However, some insurance companies may offer policies to individuals who are older than 65. It's important to note that the cost of long term care insurance generally increases with age, so it may be more expensive to purchase a policy at an older age. Additionally, the availability of coverage and the specific terms and conditions may vary based on your age and health status. It's always a good idea to consult with an insurance specialist or financial advisor to determine the best time to purchase long term care insurance based on your individual needs and circumstances.
