Oh no, you are seriously mistaken. TCC IS Conversion Coverage
http://www.opm.gov/ins... which can be provided after your COBRA would lapse. Typical Continuation coverage can cost double or triple what your COBRA policy cost. There is NO way you can coordinate your FEHB Benefits during your transition leaving the Government, and filing for Disability Retirement. Either benefits will continue to work, or they will be terminated, especially if you are about to be removed from service very soon. It took my Agency 6 Months to terminate me, while I was in LWOP or AWOL, or whatever they were calling it. My Benefits continued during this period. Bottom line, unless you are being fired for Gross Misconduct, you are able to take your current FEHB benefits into Disability Retire... and pay just the small co premium. That is assuming you win your case. If not you will be offered COBRA at full price, and then 18 Months later, Conversion coverage at about 3 times the cost. Hopefully you should never see COBRA, OR TCC.
