Ask what services, or "benefits" your plan offers that relate to disabilities.
These might be things like:
Tests or assessments
Special treatments or therapies
Special equipment or devices that help your family member communicate, move around, or do the normal things any other person can do
The main ways to find out are:
Call the customer service number on the back of your insurance card
Explore your health plan's website
Look up the benefits in your Member's Handbook.
It can be hard to get the right information!
But if you're persistent, you might be able to find other benefits from your insurance plan that can help your family member.
