Key Statistics (2024-2025)

1. Statutory Framework

IRDAI (Health Insurance) Regulations, 2016

• Regulation 2(1)(e): Definition of pre-existing disease
• Regulation 10: Waiting periods
• Regulation 11: Moratorium and permanent exclusions

IRDAI Circular on PED Definition (2020)

• Standardized 48-month look-back period
• Objective criteria for PED determination

2. Pre-Existing Disease Definition

Regulatory Definition

A pre-existing disease means any condition, ailment, injury or disease:

1. That is/was diagnosed by a physician within 48 months prior to policy inception
2. For which medical advice or treatment was recommended by a physician within 48 months
3. For which symptoms were evident and a prudent person would have sought treatment within 48 months

3. Landmark Case Law

Case 1: Pre-Existing Disease and Cancer Claims

Mediclaim Policy Holder v. Insurer

• Court: High Court of Delhi
• Case Number: W.P.(C) 2968/2020
• Date: 12-05-2020

Key Holdings:

1. Cancer developing from previously treated condition is not automatically PED
2. Enhanced sum insured applies to new diagnosis, not prior treatment limit
3. Insurer must prove proximate cause of current illness
4. Long-term policyholder entitled to benefit of doubt

Court Analysis: The Court set aside the insurers refusal to pay the claim under the mediclaim policy, noting that the petitioner had held the policy since 2002 and enhanced coverage in 2017. The court held that metastatic squamous cell carcinoma in 2020 was a new condition.

Case 2: Non-Disclosure of Cured Condition

Policyholder v. Insurer (Sarcoidosis)

• Court: High Court of Delhi
• Case Number: W.P.(C) 6304/2019
• Date: 27-07-2020

Key Holdings:

1. Disclosure of condition cured 35 years prior is not material

3. Proximate cause of claim must relate to non-disclosure
4. Coronary event unrelated to historical sarcoidosis

4. Moratorium Period Framework

IRDAI Guidelines on Moratorium

Post-Moratorium Protection
