When Indians google health insurance before buying, the second click after premium is almost always "claim settlement ratio". IRDAI knows it: every February it publishes the status-of-claims table that isolates the one metric buyers should weight most - percentage of claims paid within three months. FY24-25, released February 2026 and republished August 30 2026, is the freshest lens: standalone health insurers averaged 99.93% within three months, four of them - Acko, Niva Bupa, Aditya Birla and Galaxy - hit 100%, while public multi-line insurers ranged from Oriental 90.17% to United India 95.26%, with Shriram General and IFFCO Tokio below 90% (Economic Times Aug 30, AngelOne Feb 5). Yet OneAssure's March 30 summary of the IRDAI Annual Report notes roughly 1 in 12 health claims (about 8%) still get rejected, most often for room-rent caps or non-payable consumables. Speed and rejection are different axes - this guide shows how to read both.
Method: Three Numbers, One Dataset
We use IRDAI Annual Report FY24-25 status-of-claims as primary, via Economic Times Aug 30/Feb 16 2026 and AngelOne Feb 5 2026 breakdowns, supplemented by OneAssure Mar 30 2026 (1 in 12 rejection) and GI Council August data (Rs 94,247.6cr health claims settled FY25, 66.4% cashless). CSR = paid / (paid+outstanding+repudiated) within the period; IRDAI's "within 3 months" column is the operational TAT that maps to the master circular's 1-hour cashless authorisation and 30-day final settlement clocks. We also reference BimaNiti's August 29 four-list framework (36% of rejections are "not covered") because CSR alone does not disclose why the other ~0.07-10% were not paid within 90 days.
99.93% vs 90%: What Four Extra Weeks Mean
A 99.93% payer pays roughly 999 of every 1,000 claims within 90 days; a 90.17% payer pays 902 and leaves 98 waiting beyond - a 98x difference in cash-flow risk when hospitals ask for deposits. That is why SAHIs' 99.93% average matters more than any headline "CSR 98%" that mixes timely and delayed pays. The 100% cluster - Acko, Niva Bupa, Aditya Birla, Galaxy - were the same four highlighted in February; Niva Bupa also posted Q1 FY27 retail health +47% and 95.6% overall CSR, showing speed can accompany growth. Public insurers' 90-95% band is not a failing grade but a legacy book effect: New India (91.75%), National (91.79%) and United India (95.26%) carry larger, older reimbursement portfolios where documentation gaps lengthen TATs, whereas SAHIs are almost pure cashless retail. Shriram and IFFCO below 90% face the new July 31 Financial Condition Report disclosure on reserve adequacy and liquidity - a governance flag beyond service.
Speed Is Not Approval: Repudiation and Complaints
IRDAI's companion columns - repudiated and outstanding - plus the per-10,000-claims complaint ratio complete the picture. Economic Times paired the CSR table with a "top 10 insurers by health complaint count" where Star, Care and Niva led on absolute count, not rate - a reminder that high volume lifts both paid counts and complaint counts. Bima Bharosa data via Parliament August 4 2026 shows claim grievances were 41% of all 1,23,654 claim complaints, with GI insurers holding the largest pending pool (3,483 in Q1 FY27). A 100% timely payer with a narrow network or strict room-rent can still generate grievances at scale. That is why IRDAI's February 2026 narrative stresses claims repaid within three months alongside the solvency (150% minimum, many SAHIs >200%) and complaint-per-10k metrics.
The Four Lists That Decide "Not Covered" - Where 1 in 12 Fails
Before you sort by 100% CSR, open the policy PDF and ctrl-F four lists. One, permanent exclusions (IRDAI standard): certain cosmetic, unproven or not-medically-necessary treatments. Two, waiting periods: most policies 1-2 years for cataract/hernia/joint even without PED, PED 2-4 years (day-1 PED sold at higher premium where offered). Three, sub-limits: room-rent caps, ICU caps, procedure caps that turn Rs 8 lakh sum into Rs 3 lakh effective cover. Four, non-payables: the IRDAI consumables list (gloves, PPE, diet) hospitals bill but wordings exclude. If a rejection letter says "exclusion" without naming the list, escalate to Grievance Officer → Ombudsman - you are seeing process failure, not contract clarity. Techmagnate FY25 shows "best health insurance" +22.07% search growth, meaning more buyers chase lists; use the list check, not the ad, to convert search to suitability.
How to Choose: One-Page 3-Number Filter + Two Checks
Step one, filter to insurers with ≥95% paid within 3 months and complaint ratio below the SAHI median - that eliminates the sub-90% tail without overpaying for 100%. Step two, among that filtered set, read the four lists and compare room-rent and consumables for your likely hospital (private metro hospitals inflate room-rent-linked charges). Step three, verify cashless access: count network hospitals in your pin code, not nationally - "cashless near me" is the local intent spiking in Tier-II/III per Techmagnate (Tier-II 31.64% share). Step four, confirm TAT in writing: pre-authorisation estimate before planned procedures, and written 1-hour/30-day clock. For senior citizen covers (+21.41% search), prioritise insurers whose senior-specific CSR and portability handling (IBB routing since 2022, 45-day port notice, certificate must mention continuity benefits) are clean, not just headline SAHI 99.93%.
