In short

The sources do not say if you can buy after you leave.
Late cover may skip events that already started or were named.
Ask the seller first. Read what is excluded.

What this means

The state pages we read do not say whether a company will sell a policy after you have left. We do not know that yet. They do say that timing can change what is covered.

North Carolina says travel insurance may not cover a storm that was already named when you bought the policy [1]. Illinois says there may be set time periods when pre-existing health conditions are not covered [2]. Texas says policies may exclude cancellations for a pre-existing medical condition [3].

If you will be outside the U.S., check your health cover. Washington says Medicare does not cover medical bills for service outside the U.S. [4]. Ask the seller in writing what is excluded for a late purchase.

Your next step

Ask the seller, before you pay, if the policy can start after departure and what it leaves out. Get the answer and the policy wording in writing. The sources give no deadline.

Check it yourself

Read the policy's start date, its pre-existing condition wording, and its list of excluded events. Whether any seller sells after departure is "Don't know yet".
