Mental Health ⚠️

Limited Coverage: Most policies cover psychiatric hospitalization for acute episodes. Outpatient counseling typically NOT covered or very limited (e.g., $500/year)

Maternity/Pregnancy ⚠️

Limited Coverage: Most policies exclude pregnancy and childbirth. Some comprehensive plans offer maternity add-ons for complications only (not routine delivery).

Dental ⚠️

Basic Plans: NOT covered
Comprehensive Plans: Checkups and basic procedures up to annual limit ($500-$1,500/year typical)

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.
