Understanding Policy Limits
Annual Benefit Limits
Most policies cap total claims at $50,000-$200,000 per year. If you exceed this, you pay out-of-pocket.
Sub-Limits
Specific treatments may have lower limits:
- Dental: $1,500/year
- Optical: $300-$500/2 years
- Physiotherapy: $1,000/year
- Mental health: $2,000/year
Lifetime Limits
Some older policies have lifetime caps ($500,000-$1 million). Modern policies typically don't have lifetime limits.
Pre-Existing Conditions: The Big Exclusion
What is a Pre-Existing Condition?
Any medical condition you had symptoms of, received treatment for, or were diagnosed with before your policy started. This includes conditions you didn't know about but symptoms existed.
Waiting Periods
- Standard: 12 months for most pre-existing conditions
- Complex conditions: 24-36 months (e.g., chronic diseases)
- Accident injuries: Usually no waiting period (but ACC likely covers)
Permanent Exclusions
Some serious pre-existing conditions may be permanently excluded from your policy.
What About Accidents - ACC vs Insurance?
Important: Accidents are covered by ACC, not health insurance. If you break your leg skiing, ACC pays for treatment, not your health insurance.
Health insurance may cover:
- Faster access to private specialists for ACC-covered injuries
- Private hospital room for surgery (ACC pays medical costs, insurance pays accommodation upgrade)
- Complications from injuries that become medical conditions
Exclusions to Watch Out For
1. Cosmetic Procedures
Breast augmentation, facelifts, liposuction, etc. are NOT covered unless medically necessary (e.g., reconstructive surgery after cancer).
2. Weight Loss Surgery
Gastric bypass, lap band, etc. usually excluded unless you meet strict medical criteria (BMI >40 with comorbidities).
3. Infertility Treatment
IVF, fertility drugs, egg freezing typically NOT covered on standard policies.
4. Experimental Treatments
New, unproven therapies not yet approved by Medsafe usually excluded.
5. Self-Inflicted Harm
Injuries from suicide attempts, drug abuse, criminal activities excluded.
How to Maximize Your Coverage
1. Declare Everything Honestly
Failing to disclose pre-existing conditions can void your entire policy. When in doubt, declare it.
2. Understand Your Sub-Limits
Know your annual limits for dental, optical, physio. Don't assume unlimited coverage.
3. Check Provider Networks
Some policies only cover certain hospitals or specialists. Confirm your preferred providers are in-network.
4. Review Your Policy Annually
Coverage can change. Review your policy document each year when it renews.
