Will the premium that I pay for temporary continuation of coverage (TCC) for my 22-year-old child be included in the premium conversion plan?

No, premiums that are paid under TCC are not eligible for premium conversion. Although we realize that you may make the premium payments on behalf of your child, the TCC policyholder is the child. General tax rules do not allow pre-tax deductions for those who fail to qualify as dependents under the tax code. Since your child is no longer a qualified dependent under the FEHB Program, pre-tax premium payments are not applicable.
