As a preliminary matter, if you settled for the policy limits of your UIM policy and your claim was in excess of your UIM policy limits, then you were not obligated to reimburse your health insurance provider. Washington law is very clear on this matter; your health insurer's subrogation claim, i.e., right to reimbursement for medical bills paid for accident-related treatment, does not accrue until you are made whole. If you were not made whole, then your health insurer was not entilted to reimbursement. With regard to whether you can "re-open" your PIP, you are correct in that you have PIP coverage regardless of whether you paid any premium for that coverage assuming the insurance company cannot produce a signed waiver. However, this coverage is solely for medical bills and wage loss (80%) related to the accident--you cannot recover non-economic damages for pain and suffering, et al.; if you have outstanbing medical bills and/or wage loss, or you were forced to pay medical bills out of your settlement, then you could re-open. One other thing, if you made a claim for PIP coverage and you were denied, then you would also have a bad faith claim against the insurance company, which would entitle you to triple damages as well as an award of attorney's fees and costs incurred in pursuing the claim.
Did you sign a release? That will control whether you will be successful in reopening your case. How much are your bills? What is whole value of case? You should consult a lawyer to ferret out the answers to these questions.
You almost certainly signed a release when you settled the UM claim. The issue is whether the release can be used to shut the door on the PIP claim. Unfortunate that you had not been aware of this before you settled the UM claim. Good luck.
