Health Insurance Basics: Deductible, Co-pay, and Coverage Limits

Last updated: March 1, 2026

Health insurance is not only about premium cost. Claim rules decide whether a policy helps during an emergency. Learn the key terms before buying or renewing.

Quick Answer

Choose policy by claim usability: room-rent rule, co-pay, waiting period, and network hospitals, not just low premium.

Core Terms You Must Check

• Deductible: Amount you pay first before insurer contributes.
• Co-pay: Fixed percentage of bill you pay on every claim.
• Waiting Period: Time before specific illnesses are covered.
• Sub-limits: Caps on room rent or treatment categories.

Practical Selection Rules

1. Prefer plans with broad hospital network in your city.
2. Avoid high co-pay unless premium savings are substantial.
3. Read exclusions for pre-existing disease and maternity.
4. Keep emergency contact and policy ID easily accessible.

Common Mistakes

• Buying only tax-saving policy without coverage analysis.
• Ignoring claim settlement process and cashless support.
• Missing renewal date and losing continuity benefits.
