In short
- After your written notice, the insurer must send you its claim forms.
- If no form has come by the 16th day, send your own written proof.
- Proof of loss is due before the 91st day after the loss.
What this means
Start with written notice. Tell the insurer about the prescription expense as soon as you can.
The insurer then owes you its claim forms. If it does not provide them before the 16th day after the date of your notice, you can send your own written proof instead. That proof must cover what happened, the character of the loss, and how large it was. Texas law then treats you as having met the policy's proof-of-loss requirement [1].
There is a deadline for the proof itself. For most losses, written proof of loss is due before the 91st day after the date of the loss [2]. If it was not reasonably possible to give proof in time, the claim is not cut for that reason alone. The proof is then due as soon as reasonably possible, and no later than one year after the usual deadline [2].
Whatever you send as proof, keep the pharmacy receipt and any prior-authorization papers with it.
One limit. This chapter covers an individual accident and health policy delivered or issued for delivery in Texas [3]. It does not cover a blanket or group policy, except where the chapter says otherwise [3]. So a plan you get through work may run on different rules.
Your next step
Count to the 16th day after your written notice. If no claim form came, send your own written proof: the receipt, the date, what happened, and the amount [1]. Send it inside the time your policy sets for proof of loss. Keep a copy of everything.
Check it yourself
Check two things in your own papers. First, whether your plan is an individual policy or a group plan from work. This chapter is for individual policies, and it leaves out blanket and group policies except where it says otherwise [3]. Second, read your policy's "Claim Forms" and "Proof of Loss" clauses, and note the office address the insurer calls its designated office.

For a claim for any other loss, a written proof of loss must be provided to the insurer at the insurer's designated office before the 91st day after the date of the loss. Failure to provide the proof within the required time does not invalidate or reduce any claim if it was not reasonably possible to give proof within the required time. In that case, the proof must be provided as soon as reasonably possible but not l…
