Send it to your health plan administrator and request the 11 month extension on your COBRA continuation coverage. Was the finding made the day you lost your health insurance coverage? The COBRA Disability Extension
Before you get too excited, if you do receive the 11 month disability extension of COBRA coverage, the premium for those additional months may be increased to 150% of the plan's total cost of coverage.
Also you must notify the COBRA administrator of the Social Security disability determination within 60 days of the date of determination and before the original 18 months of COBRA continuation expire.
