What do I do if I filed for workers compensation late, and my personal insurance already paid?

I have a high deductible, so my insurance hasn't paid very much. Will it be more trouble than it is worth to pursue the workers comp claim?

Your health insurance is entitled to reimbursement from the workers comp carrier.

Depending on how long it's been, and if an initial report was ever filed, you could be looking at a fight from the workers comp insurance.
