If you have a pre-existing medical condition then you can still get private medical insurance. However, insurers do not necessarily have the same list of issues that they classify as a pre-existing conditions and each policy may apply different terms as to how pre-existing conditions are covered. Some insurers or policies will not cover certain pre-existing conditions at all whereas other may have limitations or exclusions that apply should you need treatment for an issue that relates to the existing condition. Some plans may offer coverage for pre-existing conditions although this is likely to increase the cost of the policy significantly. Different policies may also apply an exclusion period (usually 2 years) for a pre-existing condition after which time if the condition has remained trouble-free and you have not had to undergo any tests, take any medication or receive any treatments then the insurer may consider recovering the condition.
