Are my dependents eligible?

As a PEBB subscriber, you may be able to enroll your dependents on your PEBB coverage. The PEBB Program determines their eligibility based on PEBB Program rules once we receive your enrollment form and supporting documents. (Refer to Related laws and rules at the bottom of this page.)

Who is eligible?

You may enroll the following dependents:

  • Your legal spouse
  • Your state-registered domestic partner.
    • This includes substantially equivalent legal unions from other jurisdictions.
    • Strict requirements apply to these partnerships, including that one partner is age 62 or older and you live in the same residence.
  • Your children through the last day of the month in which they turn age 26. Children with a disability may be covered past the age of 26 if they qualify.

For legal definitions, refer to related laws and rules at the bottom of this page.

When you enroll eligible dependents, you may be required to provide proof of their eligibility. Visit Verify and enroll dependents for more information: employeesretirees, or PEBB Continuation Coverage members.

How are children defined?

For our purposes, the definition of children includes:

  • Children with whom you have a parent-child relationship, except when parental rights have been terminated.
  • Children of your spouse or state-registered domestic partner with whom you have a parent-child relationship, except when parental rights have been terminated.
  • Children you are legally required to support ahead of adoption.
  • Children named in a court order or divorce decree for whom you are legally required to provide support or health care coverage.
  • Children of any age with a disability.
  • Extended dependents who meet specific eligibility criteria.

Extended dependents

Extended dependents may include a grandchild, niece, nephew, or other child for whom you, your spouse, or your state-registered domestic partner are legal custodians or legal guardians. The legal responsibility is demonstrated by a valid court order and the child’s official residence with the custodian or guardian.

Foster children are not extended dependents unless you, your spouse, or your SRDP are legally required to provide support ahead of adoption.

Children with disabilities

Eligible children include children of any age with a developmental or physical disability that leaves them incapable of self-sustaining employment and chiefly dependent upon the subscriber for support and ongoing care. Their condition must have occurred before they turned age 26.

When enrolling these dependents, you must provide proof of the disability and proof the condition occurred before age 26. 

Surviving dependents eligibility

If you die, your dependents (a spouse, state-registered domestic partner, or dependent child) will lose their eligibility toward PEBB benefits. They may be eligible to enroll or defer enrollment in PEBB retiree insurance coverage as your survivor. Learn about their options.
