You may have as little as 60 days after a Medicare demand letter to pay or appeal before collection starts. And no, Medicare does not automatically get your whole settlement.

In the next 24 hours: Make a list of everyone who paid any crash-related bill after the Hilo wreck: Medicare, Med-QUEST/Medicaid, your health insurer, and your auto PIP carrier. Hawaii is a no-fault state, so your own PIP coverage is supposed to pay medical bills first up to your policy limits, regardless of fault. That matters because Medicare and Medicaid usually want reimbursement only for what they paid that should have been covered elsewhere.

If your old back, neck, or joint condition got dramatically worse after the crash, gather proof now that separates the pre-existing condition from the new aggravation. On rural Big Island roads during harvest season, crashes with grain trucks, farm equipment, and heavy vehicles often turn a manageable condition into a major one. That medical distinction affects what gets reimbursed and what stays yours.

In the next week: Request an itemized payment history from each payer. For Medicare, make sure the case is reported and ask for the conditional payment amount. For Hawaii Med-QUEST, ask whether they claim reimbursement and for a written ledger. Check whether your health plan is asserting subrogation or reimbursement.

Also ask for the settlement breakdown: medical bills, pain and suffering, lost wages, and whether procurement costs like attorney fees reduce what Medicare or Medicaid can claim. Often they do.

In the next month: Dispute charges that are unrelated, duplicated, or tied only to your prior condition instead of the crash aggravation. Watch for a trap: insurers may try to settle fast and leave you holding lien problems later.

The usual pie in a Hawaii crash case is not "Medicare gets everything." It is more like: PIP first, then valid reimbursement claims, then case costs and fees, then you. The key is making sure only crash-related, properly documented payments come out of your share.
