critical illness insurance

supplemental health coverage

Group Critical Illness Insurance with Aflac is a supplemental health benefit because it provides financial assistance to enhance your current medical coverage.

Even if you have health insurance, it might not be enough to cover costs associated with a covered medical condition — such as a heart attack. You could face unanticipated out-of-pocket expenses your medical plan doesn’t cover. Group Critical Illness Insurance can help with doctor bills, hospital stays and even some everyday living expenses if you’re dealing with a covered critical illness. This benefit provides supplemental coverage in the event of a covered medical condition so you can focus on recuperation instead of the distraction of out-of-pocket costs.

the basics

The Group Critical Illness Insurance Plan  pays you, unless otherwise assigned, a lump-sum cash benefit, when you or a covered dependent are diagnosed with a covered critical illness.

  • The Plan is insured by Aflac and administered by Mercer Voluntary Benefits.

  • Examples of covered critical illnesses currently include: cancer, heart attack, stroke, major organ transplant and coronary artery bypass surgery. Reference the Certificate of Insurance for a complete listing.

  • Any insured may receive up to 100 percent of the benefit amount upon the diagnosis of a covered critical illness. Benefits are based on the benefit amount in effect on the critical illness date of diagnosis.

  • The current benefit amounts that you can purchase are up to $20,000 for you as an eligible employee and up to $10,000 for your covered eligible dependent(s). Dependent children are automatically covered at 50 percent of the employee face amount.

  • This coverage is voluntary. You must enroll to be covered.

  • This coverage is available to you at group rates. You pay the entire cost of coverage through regular payroll deductions on an after-tax basis. You can view premiums online when you enroll, or you can call the Chevron HR Service Center.

  • This coverage includes a waiver of premium feature. If you become Totally Disabled (as defined in the Certificate of Insurance) due to a covered critical illness prior to age 65, after 90 continuous days of total disability, premiums for all insureds will be waived up to 24 months, subject to the terms of the plan.

who's eligible to participate

Except as described below, you’re generally eligible for this Plan if you’re considered by Chevron to be a common-law employee of Chevron Corporation or one of its subsidiaries that it has designated to participate in the Omnibus Health Care Plan and you meet all of the following qualifications:

  • You’re paid on the U.S. payroll of Chevron Corporation or a participating company.
  • You’re assigned to a regular work schedule (unless you’re on a family leave, disability leave,  short union business leave, furlough leave, military service leave or leave with pay) of at least 40 hours a week, or at least 20 hours a week if such schedule is an approved part-time work schedule under the corporation’s part-time employment guidelines.
  • If you’re a casual employee, you’ve worked (or are expected to work) a regular work schedule for more than four consecutive months.
  • You’re in a class of employees designated by Chevron as eligible for participation in the plan. 
However, you’re still not eligible if any of the following applies to you:
  • You’re not on the Chevron U.S. payroll, or you’re compensated for services to Chevron by an  entity other than Chevron — even if, at any time and for any reason, you’re deemed to be a  Chevron employee.
  • You’re a leased employee or would be a leased employee if you had provided services to Chevron for a longer period of time.
  • You enter into a written agreement with Chevron that provides that you won’t be eligible.
  • You’re not regarded by Chevron as its common-law employee and for that reason it doesn’t withhold employment taxes with respect to you — even if you are later determined to have been Chevron’s common-law employee.
  • You’re a member of a collective bargaining unit (unless eligibility to participate has been negotiated with Chevron).
  • You’re a professional intern.
  • You’re designated by Chevron as a seasonal employee.  
Chevron Corporation, in its sole discretion, determines your status as an eligible employee and whether you’re eligible for the plan. Subject to the plan’s administrative review procedures, Chevron Corporation’s determination is conclusive and binding.  If you have questions about your eligibility for this plan, you should contact the Chevron Human Resources Service Center.

To be eligible for coverage, when you enroll you’ll be required to attest to meeting certain eligibility requirements, including but not limited to:

  • You are actively at work for Chevron at the time of enrollment. 
  • The person(s) to be insured has comprehensive health benefits from an insurance policy, an HMO plan, or an employer’s health benefits. You do not have to be enrolled in Chevron health coverage. This means you can have comprehensive health coverage from another source.
  • Your spouse is not disabled or unable to work. Spouse includes Domestic Partner as defined in California Family Code Section 297.
When you enroll, you’ll be required to attest to meeting eligibility requirements
You can enroll your spouse for coverage. 
You can’t enroll your spouse for coverage if he or she is either of the following:
  • Enrolled as an eligible employee.

  • Enrolled as an eligible employee.
  • Disabled or unable to work. 
To qualify for benefits available to eligible dependents of Chevron employees, you may be required to verify the eligibility of any new dependents you enroll in your Chevron health plans by completing the dependent verification process. When you enroll a domestic partner, you will be required to complete, sign and notarize the Chevron Affidavit of Domestic Partnership (F-6) form as part of the dependent verification process. By signing the affidavit, you certify that you and your partner meet the qualifications as identified on the Chevron Affidavit of Domestic Partnership (F-6) form. The form will be provided to you with your dependent verification materials or can be requested by contacting the HR Service Center. 
You can enroll a dependent child for coverage if under age 26 and is your or your spouse’s natural children, stepchildren (including existing children of new domestic partners), legally adopted children, or children placed for adoption. Newborn children are automatically covered from the moment of birth for 60 days. Newly adopted children are automatically covered for 60 days also. See certificate for details. 
Dependent children must be younger than age 26; however this limit will not apply to any insured dependent child who is incapable of self-sustaining employment due to mental or physical handicap and is chiefly dependent on a parent for support and maintenance. Proof of a child’s incapacity and dependency must be provided within 31 days after the date when coverage would normally end. 
Your child isn’t eligible under family coverage if he or she is either of the following: 
  • Enrolled for single coverage as an eligible employee. 
In addition, your “other dependents” are not eligible for coverage under this plan. 
You may be required to provide proof of your child’s eligibility before he or she can be enrolled by following the dependent verification process.  
Eligibility rules will be enforced at the time of a claim. 
If both you and your spouse are eligible employees, each of you can enroll for employee coverage, or one of you can enroll for employee and spouse or family coverage and include the other as a covered dependent.
