A High-Deductible Health Plan (HDHP) is a type of health insurance that requires policyholders to pay a higher deductible before their insurance coverage kicks in. This means that individuals must cover more of their initial medical expenses out-of-pocket. HDHPs often have lower monthly premiums, making them appealing for those who are generally healthy and do not expect to need frequent medical care. These plans are often paired with Health Savings Accounts (HSAs), which allow individuals to save money tax-free for medical expenses. Contributions to an HSA can help offset the high deductible, providing a financial cushion for unexpected healthcare costs.
