HSA-compatible health insurance plans contain the same pre-existing condition provisions present in other health insurance plans.
Most individual plans will apply the pre-existing condition exclusion -- whatever your previous health insurance history. Employer-sponsored plans follow the dictates of HIPAA, waiving the pre-existing condition exclusion waiting period based on prior continuous health insurance coverage.
Unless coverage is provided through an employer-sponsored benefits program, your HSA-compatible health insurance will be subject to normal insurance company underwriting requirements.
If ongoing medical circumstances have prevented you from obtaining traditional medical insurance, you are unlikely to get a better outcome in applying for an HSA-compatible high deductible health plan.
What if you're subject to a new health plan's pre-existing condition exclusion? If you've previously established an HSA, you've reduced your financial risk.
You can use pre-tax HSA funds to pay qualified expenses that are not reimbursed by your new health insurance company. This includes medical expenses attributable to any pre-existing condition.
With an HSA, you have a tax-advantaged health care funding tool that will provide financial cushion in many health insurance transition scenarios -- including payment of COBRA premiums and the purchase of other health insurance while you're receiving unemployment compensation.
