COB's Effect On Benefits below in this section for details on primary and secondary plans.
If you do not know which is your primary plan, you or your provider should contact any of the health plans to verify
which plan is primary. The health plan you contact is responsible for working with the other plan(s) to determine
which is primary and will let you know within 30 calendar days.
Caution: All health plans have timely filing requirements. If you or your provider fails to submit your claim to your
secondary plan within that plan's claim filing time limit, the plan can deny the claim. If you experience delays in
the processing of your claim by the primary plan, you or your provider will need to submit your claim to the
secondary plan within its claim filing time limit to prevent a denial of the claim.
To avoid delays in claims processing, if you are covered by more than one plan you should promptly report to
your providers any changes in your coverage.
COB Definitions
For the purposes of COB:
• A plan is any of the following that provides benefits or services for medical or dental care. If separate contracts
are used to provide coordinated coverage for group members, all the contracts are considered parts of the
same plan and there is no COB among them. However, if COB rules don't apply to all contracts, or to all
benefits in the same contract, the contract or benefit to which COB doesn't apply is treated as a separate plan.
• “Plan” means: Group, individual or blanket disability insurance contracts, and group or individual contracts
issued by health care service contractors or HMOs, closed panel plans or other forms of group coverage;
medical care provided by long-term care plans; and Medicare or any other federal governmental plan, as
permitted by law.
• “Plan” doesn't mean: Hospital or other fixed indemnity or fixed payment coverage; accident-only coverage;
specified disease or accident coverage; limited benefit health coverage, as defined by state law; school
accident type coverage; non-medical parts of long-term care plans; automobile coverage required by law to
provide medical benefits; Medicare supplement policies; Medicaid or other federal governmental plans,
unless permitted by law.
• This plan means your plan's health care benefits to which COB applies. A contract may apply one COB
process to coordinating certain benefits only with similar benefits and may apply another COB process to
coordinate other benefits. All the benefits of your Premera Blue Cross plan are subject to COB, but your plan
coordinates dental benefits separately from medical benefits. Dental benefits are coordinated only with other
plans' dental benefits, while medical benefits are coordinated only with other plans' medical benefits.
• Primary plan is a plan that provides benefits as if you had no other coverage.
• Secondary plan is a plan that is allowed to reduce its benefits in accordance with COB rules. See COB's
Effect On Benefits later in this section for rules on secondary plan benefits.
• Allowable expense is a health care expense, including deductibles, coinsurance and copayments, that is
covered at least in part by any of your plans. When a plan provides benefits in the form of services, the
reasonable cash value of each service is an allowable expense and a benefit paid. An amount that isn't
covered by any of your plans isn't an allowable expense.
The allowable expense for the secondary plan is the amount it allows for the service or supply in the absence of
other coverage that is primary. This is true regardless of what method the secondary plan uses to set allowable
expenses.
The exceptions to this rule are when a Medicare, a Medicare Advantage plan, or a Medicare Prescription Drug
plan (Part D) is primary to your other coverage. In those cases, the allowable expense set by the Medicare
plan will also be the allowable expense amount used by the secondary plan.
• Custodial parent is the parent awarded custody by a court decree or, in the absence of a court decree, is the
parent with whom the child resides more than half of the calendar year, excluding any temporary visitation.
Primary And Secondary Rules
Certain governmental plans, such as Medicaid, are always secondary by law. Except as required by law,
Medicare supplement plans and other plans that don't coordinate benefits at all must pay as if they were primary.
A plan that doesn't have a COB provision that complies with Washington regulations is primary to a complying
plan unless the rules of both plans make the complying plan primary. The exception is group coverage that
supplements a package of benefits provided by the same group. Such coverage can be excess to the rest of that
