KASP (Karunya Arogya Suraksha Padhathi) is Kerala’s state health insurance scheme that implements Ayushman Bharat (PMJAY) at the state level. It provides free cashless health cover of up to ₹5 lakh per family per year at empanelled government and private hospitals across Kerala. Eligible families include BPL households, SECC 2011 listed families and others specified by the Kerala government covering approximately 42 lakh families. There is no premium, no registration fee and no card charge. To enrol, visit any empanelled hospital’s KASP kiosk with your Aadhaar card and ration card for biometric e-KYC verification. Alternatively call helpline 104 or 14555.

Yes. NRIs can purchase health insurance plans for parents residing in Kerala from any private insurer. Payment must be from an Indian bank account — NRE or NRO account linked to an Indian bank works fine. The NRI also gets Section 80D income tax deduction of up to ₹50,000 for parents above 60 years of age if the premium is paid from an Indian account. Recommended plans for elderly Kerala parents include Care Supreme Senior, Star Health Red Carpet and Niva Bupa Senior First. All offer cashless hospitalisation at network hospitals in Kerala without requiring the NRI to be present — the parents can handle the cashless claim directly at the hospital.

A minimum of ₹10-15 lakh floater cover is recommended for a family of four in Kerala in 2026. For urban Kerala (Kochi, Thiruvananthapuram, Kozhikode), ₹15-25 lakh base cover is more appropriate given rising private hospital costs. A single cardiac bypass surgery or cancer treatment at a Kerala private hospital costs ₹8-20 lakh in 2026. The most cost-efficient strategy is a ₹10-15 lakh base plan plus a super top-up policy of ₹50 lakh at a low additional premium of ₹3,000-8,000 per year. This gives ₹60-65 lakh total cover at a fraction of the cost of a single high-value base plan.

Under Section 80D of the Income Tax Act you can claim deduction on health insurance premiums paid. For self, spouse and dependent children the deduction is up to ₹25,000 per year (₹50,000 if you are a senior citizen). Additionally if you pay health insurance premium for your parents you get an extra ₹25,000 deduction (₹50,000 if parents are senior citizens aged 60 or above). Maximum total deduction is ₹1,00,000 per year if both you and your parents are senior citizens. This deduction applies under both Old and New Tax Regime for health insurance premiums.

Claim settlement ratio (CSR) is the percentage of health insurance claims an insurer settles out of total claims received. A higher CSR means fewer claims are rejected. According to IRDAI Annual Report 2025-26, the best CSRs among major health insurers are: HDFC ERGO 96.71 percent (best), Aditya Birla 95.2 percent, Care Health 93.13 percent, Niva Bupa 91.6 percent, Bajaj Allianz 91 percent, Star Health 84.97 percent. The industry average is 91.22 percent. Star Health being below industry average means roughly 1 in 7 claims is rejected — a significant risk especially for serious hospitalisations. Always choose an insurer with CSR above 90 percent.

A super top-up plan provides additional health coverage that kicks in after your base policy limit is exhausted in a policy year. For example a ₹50 lakh super top-up with ₹10 lakh deductible pays for hospitalisation expenses above ₹10 lakh up to ₹60 lakh total. Super top-up premiums are very affordable — ₹3,000 to 8,000 per year for ₹20-50 lakh additional cover — because serious illnesses requiring above-deductible claims are statistically uncommon. Kerala families should consider: KASP free cover as base (if eligible) plus a super top-up for serious events. Or a ₹10 lakh private base plan plus a ₹50 lakh super top-up for total ₹60 lakh cover at approximately ₹20,000-28,000 per year combined premium.

Yes. Star Health Insurance has the largest cashless hospital network in Kerala among private health insurers with over 700 empanelled hospitals across all 14 Kerala districts including smaller towns like Kottayam, Thrissur, Palakkad, Malappuram and Kollam where other insurers have limited presence. This makes Star Health the preferred choice for Kerala families in non-metro districts where HDFC ERGO or Niva Bupa may have fewer network hospitals. However Star Health’s claim settlement ratio of 84.97 percent is below the industry average of 91.22 percent — the trade-off between network breadth and claim reliability should factor into your decision based on where you live in Kerala.
