Health plan ID card examples showing TDI or DOI


We can help with issues involving health plans we regulate. We don’t regulate most health plans.

To find out if we regulate your health plan, check your health insurance card. If it has “TDI” or “DOI” on it, we can help you.

As you can see from the examples below, “TDI” or “DOI” can show up in various locations on ID cards.
