Certificate of Prior Creditable CoverageIf you do not get a certificate
If your new plan imposes a preexisting condition exclusion, your claims processing will go smoother if you don’t delay. There are other ways to show you had creditable coverage with evidence of your prior health coverage which can include:

* Copies of premium payments or other documents showing evidence of coverage;
* Explanation of benefit forms; and
* Verification by a doctor or your former health plan.
