Key insurance terms that start with "G"

A Good Faith Estimate (GFE) is a written cost estimate that health care providers are required to give you before you receive scheduled, non-emergency services. The requirement was established by the No Surprises Act and took effect January 1, 2022. It applies to uninsured patients and self-pay patients; for insured patients, it is available upon request.

The GFE must include:

• Expected charges for the primary service
• Costs for related services expected to be provided at the same time (anesthesia, lab work, facility fees)
• Diagnosis codes and service codes associated with the expected care
• Provider and facility information

If your final bill exceeds your Good Faith Estimate by more than $400, you have the right to dispute it through the No Surprises Act’s Patient-Provider Dispute Resolution process. You must initiate the dispute within 120 days of receiving your bill.

The GFE is not a guarantee of final cost — it’s an estimate based on planned services. Unexpected complications or additional services during the visit may result in higher charges.

Guaranteed issue is the ACA requirement that health insurance companies must sell you a health plan regardless of your health history, pre-existing conditions, or how sick you are. They cannot turn you down, charge you more based on health status, or exclude coverage for specific conditions.

Before the ACA, guaranteed issue didn’t apply to most individual market plans. Insurers could review your health history, charge higher premiums for pre-existing conditions, exclude certain conditions from coverage, or outright deny your application.

Under current ACA rules, guaranteed issue applies to:

• All ACA Marketplace plans (individual and family)
• Employer-sponsored group plans
• Medicaid and CHIP

Guaranteed issue does NOT mean you can enroll at any time. You must enroll during Open Enrollment or a Special Enrollment Period triggered by a qualifying life event. Guaranteed issue just means that when you are eligible to enroll, the insurer cannot refuse you or price you differently based on health.

Short-term health plans and some non-ACA-compliant products are exempt from guaranteed issue — they can still decline coverage based on health history.

Group health insurance is health coverage offered to a group of people — typically employees of a company or members of an organization — under a single policy. Employers are the most common sponsors, though unions, professional associations, and other groups can also offer group plans.

Group coverage typically offers lower premiums than individual plans because risk is spread across a large pool of enrollees, and employers usually contribute a portion of the premium — often 50–80% for the employee, though family coverage contributions vary widely.

Key characteristics of group health insurance:

• Enrollment is limited to eligible employees and their dependents
• Coverage is not portable — it ends when you leave the employer (COBRA can extend it temporarily)
• Insurers cannot exclude employees based on pre-existing conditions
• Plans with 50 or more full-time equivalent employees must offer coverage that meets ACA minimum value and affordability standards

If you have access to an affordable group plan through your employer, you generally do not qualify for Premium Tax Credits on the Marketplace — even if a Marketplace plan might cost less after subsidies.

A grievance is a formal complaint you file with your health insurance company about any aspect of the plan or its services that does not involve a denial of benefits. Grievances address problems with service quality, access to care, billing practices, or how your plan is being administered — not coverage decisions (which are handled through the appeals process).

Common reasons to file a grievance:

• Difficulty getting timely appointments with in-network providers
• Rude or unprofessional treatment from plan staff or contractors
• Billing errors or confusion about your Explanation of Benefits
• Failure to receive required notices or communications
• Problems accessing care management programs or services
• Concerns about wait times at network facilities

The grievance process is separate from an appeal. If your insurer denies a claim, prior authorization request, or coverage for a service, that’s handled through the appeals process. If you’re unhappy with how the plan operates or how you were treated — but not with a specific coverage decision — that’s a grievance.

Insurers are required to acknowledge grievances within a set timeframe and provide a resolution. If you’re unsatisfied with the outcome, you can escalate to your state insurance department.

A health plan that existed on March 23, 2010, when the Affordable Care Act was signed into law and has maintained its status since then. Grandfathered plans are exempt from some ACA requirements like covering preventive care without cost sharing. However, they must still comply with most ACA protections.

A grace period is a window of time after a missed health insurance premium payment during which your coverage remains active and your insurer cannot terminate your policy. It gives you time to catch up on a missed payment before losing coverage.

Grace period length depends on how you pay for your coverage:

• ACA Marketplace plans with APTC: 90-day grace period. However, your insurer can suspend payment of claims after day 30. If you don’t pay by day 90, coverage is terminated retroactively to the end of day 30, and any claims paid between day 31 and day 90 may be clawed back from providers.
• ACA Marketplace plans without APTC: 30-day grace period. Coverage terminates if the premium isn’t paid within 30 days.
• Employer-sponsored plans: Grace period terms vary by employer and are governed by the plan documents.

If your coverage is terminated due to non-payment, losing coverage is a qualifying life event that opens a Special Enrollment Period to re-enroll. However, you may have a gap in coverage and any claims incurred after termination will not be covered.

A Gold plan is the second-highest metal tier on the ACA Marketplace. It covers approximately 80% of average health care costs — you pay about 20% through deductibles, copays, and coinsurance. Gold plans have higher monthly premiums than Bronze or Silver, but significantly lower out-of-pocket costs when you use care.

Gold is generally the best fit for people who use health care regularly — those who see specialists frequently, take ongoing prescription medications, or anticipate significant medical expenses during the plan year. The higher premium is often offset by lower cost-sharing over the course of the year.

One important comparison: if you qualify for Cost-Sharing Reductions (CSR) on a Silver plan, a CSR-enhanced Silver can actually outperform Gold on total annual cost despite Gold’s higher actuarial value. CSR is only available on Silver plans, so if you’re in the 100%–250% FPL income range, compare your CSR Silver options before defaulting to Gold.

A generic drug is a medication that contains the same active ingredient, in the same strength, dosage form, and route of administration as a brand-name drug — and is FDA-approved as therapeutically equivalent. Generic drugs become available after the patent on the original brand-name drug expires, typically 20 years after the initial patent filing.

Generics are significantly cheaper than brand-name equivalents because manufacturers don’t bear the original research and development costs and compete with multiple other manufacturers once the patent expires. On most insurance formularies, generics are placed on the lowest-cost tier (Tier 1 or 2), resulting in the lowest copays for consumers.

Key facts about generic drugs:

• The FDA requires generics to be bioequivalent to the brand-name drug — meaning they work the same way in the body
• Inactive ingredients (binders, fillers, dyes) may differ from the brand-name version, but the active ingredient is the same
• Generic drugs save Americans billions of dollars annually in prescription costs
• If a generic is available for your medication, your doctor or pharmacist can typically make the switch without a new prescription

When comparing plans during Open Enrollment, check the formulary to confirm your generic drugs are covered on the lowest tiers — this directly affects your monthly prescription costs.
