Health insurance with pre-existing conditions (PEDs) often causes confusion—and claim denials. With rising healthcare costs, securing coverage for conditions like diabetes, hypertension, or asthma is crucial. This guide decodes what the law says, what claim nominals insurers use, and how you can protect yourself and your finances.
1️⃣ What Is a Pre-Existing Disease (PED)?
A pre-existing disease means any health condition you had before starting your insurance policy, whether diagnosed, treated, or even just symptomatic. Legislators and insurers define it differently:
- In India, a PED means any disease “diagnosed or treated by a physician up to 36 months before policy start” (reddit.com, economictimes.indiatimes.com).
- In the U.S., before the Affordable Care Act (ACA) in 2014, insurers could apply PED exclusions. Now, combating adverse selection, the ACA prohibits denying coverage to individuals with PEDs .
2️⃣ Legal Foundations: Good Faith & Moratorium Rules
Health insurance contracts require “uberrimae fidei”—utmost good faith. Courts emphasize full disclosure:
- Karnataka High Court upheld claim rejection when PEDs were concealed (reddit.com, policybazaar.com).
- The NCDRC held that mere suspicion is insufficient—insurers must prove non-disclosure and intentionality (taxguru.in).
3️⃣ Waiting Periods: Know the Timeframe
Most policies impose a PED waiting period. In India, this was reduced from 4 years to 3 years per IRDAI Regulation (effective April 2024) (moneycontrol.com). Typical durations:
- Plans may vary—some fully cover PEDs after 2 years.
- Add-on riders (e.g., PED buyback rider) can reduce or waive waiting terms (bajajfinservmarkets.in).
4️⃣ When Is a Claim Valid?
You can claim after the waiting period. Key points:
- Claim must be for treatment post-waiting-period.
- PED must be disclosed at purchase.
- Insurer must not use conjectures or undisclosed symptom claims to reject valid claims.
Case study: A widow successfully claimed ₹19.4 lakh when her husband’s death was unrelated to undisclosed diabetes. Delhi State Consumer Commission ruled pre-existing diseases alone couldn’t be cause for denial (verywellhealth.com, reddit.com, policybazaar.com).
5️⃣ When Can Claims Be Rejected?
Insurers may deny claims if:
- You concealed a known PED when buying the policy.
- Claims were made during the waiting period.
- A moratorium hasn’t completed (in India, moratorium is 60 continuous months) (investopedia.com, moneycontrol.com).
- Documentation shows a PED existed pre-policy and wasn’t declared.
Unless fraud is proven, claims cannot be rejected just because of undeclared, unknown ailments after the moratorium ends.
6️⃣ Moratorium & Contestability
- Waiting period: Time before PED treatment is covered (typically 3 years).
- Moratorium period: After 5 years of uninterrupted coverage, insurers cannot contest claims based on non-disclosure, unless there’s fraud (policybazaar.com, moneycontrol.com, bajajfinservmarkets.in).
This secures your coverage even if prior undisclosed conditions emerge later.
7️⃣ Disclosure Is Your Duty
Honesty on the proposal form is vital. Policy terms demand disclosure of past hospitalizations, medication, tests, family history, etc. Any intentional misrepresentation can lead to claim rejection or policy cancellation (tataaig.com).
Reddit insight:
“Insurance works on the concept of ‘uberima fidei’ … Wilful covering up of a pre existing condition would be grounds for claim repudiation.” (reddit.com)
8️⃣ Medical Underwriting & Post-Claim Scrutiny
For some policies (short-term, critical illness), insurers use medical underwriting—examining your medical history before issuance or after a claim (verywellhealth.com). Scrutiny includes:
- ICD-10 diagnosis codes
- Doctor’s notes
- Lab reports
- Timeframes for symptom onset vs. policy purchase
9️⃣ What to Do if Your Claim Is Denied
- Check your policy wording for PED clauses and waiting periods.
- File a first appeal with the insurer under their grievance process.
- Escalate to Insurance Ombudsman—claim outcomes often favor the insured after moratorium or unrelated cause (timesofindia.indiatimes.com).
- Consider legal recourse if denial violates CSRs or provisions. High courts often side with honest claimants.
🔟 Avoiding Sneaky Loopholes
- Use pre-existing disease riders or transparent policies with 1–2 year waiting terms.
- Maintain continuous premium payments to complete moratorium.
- Keep organized medical records including tests, referrals, and doctor consultations.
- Always stick to network hospitals for cashless claims.
- Confirm before policy purchase whether your PED is allowed or permanently excluded per IRDAI guidelines (timesofindia.indiatimes.com, bajajfinservmarkets.in, irdai.gov.in).
