Insurance · 10 most-confused terms decoded in plain English

Insurance Glossary

Indian insurance documents read like contracts written by lawyers for lawyers — because they are. Sum insured is not cover amount; deductible is not co-payment; exclusion is not waiting period. 80% of claim disputes start with terminology confusion. This glossary decodes the 10 most-confused terms with real examples. Each links to a deeper /glossary/[slug] entry. Save this page; you will consult it every renewal cycle.

Who needs this

Anyone reading a policy document (proposal form, certificate of insurance, claim form, renewal notice) and getting confused by jargon. Especially first-time buyers comparing 3-4 plans and finding the same word means different things across insurers. Adult children helping elderly parents understand their existing policies.

Key decisions

  1. Q1

    Sum Insured vs Cover Amount vs Policy Value — different?

    SUM INSURED = max amount insurer pays in a policy year (annual cap). COVER AMOUNT = same thing, casual term. POLICY VALUE / FACE VALUE = lump sum payable to nominees in TERM/LIFE insurance on death. Critical distinction: Sum Insured is per-year (renews each year). Policy Value is lifetime in life insurance. So '₹10L health insurance' = ₹10L per year refresh. '₹1Cr term insurance' = ₹1Cr lump sum to family on death. In a FAMILY FLOATER plan, sum insured is SHARED across family — ₹10L floater for 4 people = total ₹10L per year for everyone combined (not ₹10L each).

  2. Q2

    Premium vs Premium Loading vs Premium Increment — what is the difference?

    PREMIUM = annual cost of insurance (₹15K-₹50K typical health, ₹15K-₹25K term). PREMIUM LOADING = surcharge added for pre-existing diseases / risky occupations / smoker status (typically +20-50% over base). PREMIUM INCREMENT = year-over-year increase (insurer-decided, ~10-15%/year for health insurance due to medical inflation). 'Locked premium' / 'guaranteed premium' = no increment for a specified period (rare, 3-5 years max in India). Watch out for 'No premium loading for first year' marketing — loading kicks in Year 2 onwards.

  3. Q3

    Deductible vs Co-Payment vs Sub-Limit — all reduce payouts?

    DEDUCTIBLE = fixed amount YOU pay before insurer starts paying. ₹10K deductible on ₹50K bill = you pay ₹10K, insurer pays ₹40K. Reduces premium 20-30%. CO-PAYMENT = percentage of EVERY claim YOU pay (e.g., 20% co-pay). ₹50K bill, 20% co-pay = you pay ₹10K, insurer pays ₹40K. Same math at low value, very different at high (₹5L bill: 20% co-pay = ₹1L out of pocket). SUB-LIMIT = cap on specific expense within total cover. ₹10L health insurance with ₹5K/day room rent sub-limit = you stay in ₹15K room, claim 1/3 (proportionate deduction on EVERYTHING including doctor / drugs / OT). Sub-limits are the #1 hidden trap.

  4. Q4

    Waiting Period vs Cooling-Off Period vs Free-Look Period?

    WAITING PERIOD = time from purchase to when coverage starts. Initial 30 days standard (illness only, accidents covered Day 1). Pre-existing diseases (PED) 2-4 years. Maternity 2-4 years. Specific illnesses (cataract, hernia, knee replacement) 2 years. COOLING-OFF / FREE-LOOK = 15-day window AFTER buying to cancel and get full refund minus admin charges. Mandated by IRDAI for all life and health insurance. Read your policy in this 15-day window — most rejections later trace back to not reading sub-limits / exclusions during free-look.

  5. Q5

    Rider vs Add-on vs Floater vs Top-up — same thing?

    RIDER = additional coverage attached to base policy (critical illness rider on term plan, accidental death rider). Lower premium than standalone. ADD-ON = same concept, different insurer terminology. FLOATER = single sum insured shared across family members (vs INDIVIDUAL = each person has own cover). TOP-UP / SUPER TOP-UP = additional cover that kicks in AFTER base sum insured exhausted. ₹5L base + ₹15L super top-up = total ₹20L cover but premium is 60-70% cheaper than ₹20L individual plan because top-up only pays after deductible (₹5L base exhaustion).

  6. Q6

    Pre-existing Disease (PED) vs Lifestyle Disease vs Chronic Condition?

    PRE-EXISTING DISEASE (PED) = any illness diagnosed BEFORE policy start date (regardless of treatment). Waiting period 2-4 years. Must be DECLARED at proposal — non-disclosure = full claim rejection (#1 rejection reason). LIFESTYLE DISEASE = diabetes, hypertension, obesity-related — most insurers cover after PED waiting period. CHRONIC CONDITION = long-term illness needing ongoing treatment (kidney disease, COPD). Some insurers exclude chronic conditions entirely or charge premium loading. CONGENITAL DISEASE = present at birth. External (cleft palate, deformities) usually excluded; internal (heart defects) often covered.

  7. Q7

    Cashless vs Reimbursement — coverage difference?

    CASHLESS = insurer pays hospital directly. Available at NETWORK HOSPITALS only (each insurer empanels 5,000-15,000). Process: pre-authorisation in 30-60 mins, treatment, you pay only non-covered items. REIMBURSEMENT = you pay upfront, claim back in 30-45 days. Works at ANY hospital but you front the cash. NETWORK is the keyword — your insurer's network may not include your nearest top hospital. Verify via insurer's app BEFORE you need treatment. Some plans offer 'Cashless Everywhere' (pay 5-10% higher premium) — kicks reimbursement automatically at non-network.

  8. Q8

    Sum Insured Restoration vs Refill vs Recharge — bonus cover?

    SUM INSURED RESTORATION (also REFILL / RECHARGE) = automatic top-up if base sum insured exhausted during policy year. Triggered by separate hospitalisation (not same illness's continuation). ₹10L base + 100% restoration = if you exhaust ₹10L in Apr (kidney stone surgery), then need ₹8L in Oct (different illness), insurer pays from restored ₹10L. Some plans 'unlimited restoration', some 'once per year', some 'only for unrelated illnesses'. Read fine print. Premium for restoration: +15-25% above base — usually worth it for families with multiple high-risk members.

  9. Q9

    Standard vs Critical Illness vs Disability Insurance — different?

    STANDARD HEALTH INSURANCE = covers hospitalisation expenses. Pay-as-you-go, reimbursement model. CRITICAL ILLNESS = LUMP SUM payout on diagnosis of specified illness (cancer, heart attack, stroke, kidney failure, paralysis). Use the money however you want — treatment, income replacement, debt clearance. DISABILITY INSURANCE / PERSONAL ACCIDENT = lump sum + monthly income on disability (permanent or temporary). All three are SEPARATE products — having one does not cover the other. Comprehensive coverage = stack ₹15-25L health + ₹15-25L CI + ₹25L PA.

  10. Q10

    Exclusion vs Limitation vs Conditional Coverage?

    EXCLUSION = never covered (always rejected). Cosmetic surgery, fertility treatment, suicide (first 12 months), substance abuse, war/civil unrest. Listed in policy 'Exclusions' section. LIMITATION = covered but with cap. Maternity ₹50K cap, AYUSH treatment ₹50K cap. CONDITIONAL COVERAGE = covered IF specific condition met. Critical Illness covered IF diagnosed BY specified ICD-10 code AND survives 30 days post-diagnosis (survival period — common in CI plans). Read all three sections (Exclusions / Limitations / Definitions) before buying. Most claim rejections trace back to one of these — often unread.
