Your disability retirement type may change depending upon the circumstances.
If your original disabling condition or conditions worsen, improve, or recover, the department may adjust your benefit.
Example: A member retires on a duty-related disability retirement due to a knee injury. The member has surgery related to the knee injury after retirement and suffers side effects from the surgery that prevent the member from performing any substantial gainful employment. The member is eligible to have their benefit adjusted because the aggravation is directly related to the original injury.
Example: A member retires on a duty-related disability retirement due to a knee injury. The member reinjures the knee in a skiing accident and is rendered unable to perform any substantial gainful employment. The member is not eligible to have their benefit adjusted because the aggravation is the result of a succeeding cause and not the original injury.
Example: A member retires on a duty-related disability retirement due to a knee injury. The condition gradually worsens over time until the member is no longer capable of substantial gainful employment. The member is not eligible to have their benefit adjusted because the aggravation is due to aging.
