Payment of professional insurance claim taxable?

I am a self employed sales rep. One of my suppliers never payed me. I won a judgement against him and he filed for Chapter 7. I have professional insurance and submitted the claim to them as an uncollectable acct receivable. If they pay the claim is the payment a taxable event? I was not able to deduct the nonpayment of receivables on my taxes as I use cash basis. I look forward to anyone's comments. Thanks
