What to do now

  1. 1

    Check the basis and start date

    Federal rule says an approval letter must state the basis for coverage. It must also state the start date. Find these two facts on your own letter.

  2. 2

    Note what you must report and when

    Your letter should explain what changes you need to report, like income or address. It should say how to report them. This keeps your child's coverage accurate.

  3. 3

    Read the benefits and cost information

    Approval letters must list basic facts on benefits and services. They must list any premiums or cost sharing too. Ask your state CHIP agency if something is unclear.

  4. 4

    Know your review right

    Every CHIP letter must explain your right to ask for a review. Keep the letter. You may need it later if something changes.

Deadline

An approval letter does not set one fixed federal deadline. But it may list a date to report a change. It may list a date to verify information or ask for a review. That date is set by your state. Check your own letter for the real date.

We did not verify a general deadline for this letter. Your letter shows the real date.
