HMSA Children’s Plan Application


To apply for The HMSA Children’s Plan, please print and fill out this form. Mail it to HMSA at the address below.

To apply:
A completed application and payment must be received by the 12th of the month for a proposed effective date of 1st of the following month.

If re-enrolling in The HMSA Children’s Plan in the same year, you must apply within 31 days from a qualifying event or be subject to November’s open enrollment for January 1 effective date.

To avoid delays, please make sure your application is complete.

Please complete a separate form for each child you want to enroll.

  1. Fill in your name, address, and phone numbers.
  2. Check “yes” if your child has other medical coverage and fill in the name of the carrier. Please note that this plan doesn’t coordinate benefits with any other medical insurance plan. Once accepted into this plan, members can’t have any other medical insurance coverage.
  3. Fill in your child’s present or former HMSA subscriber ID.
  4. Fill in the child’s name, sex, birth date, and Social Security number. Then choose a health center and primary care provider that’s participating with the HMSA Children’s Plan. Under "Current Provider?" check "Yes" if the provider you selected is your child’s current provider. If the box isn’t checked and the provider isn’t accepting new patients or is a specialist, we won’t be able to enroll you with that provider.
  5. Read the agreement, then sign and date the application on behalf of your minor child.

Please include a check or money order payable to “HMSA” for your child’s first month’s premium. If you are enrolling more than one child in this plan, you may submit one payment for the combined premiums for the first month of coverage.
