Bypass surgery (CABG) claim rejected or cut?

Coronary artery bypass grafting (CABG) reroutes blood around blocked heart arteries. It is major open-heart surgery with a stay of a week or more. If your insurer has rejected or cut the claim, these are the reasons that come up most for bypass surgery, the rules that apply, and what to do next.

Why bypass surgery claims get rejected or cut

Non-disclosure of blood pressure, diabetes, cholesterol or earlier chest pain.
Pre-existing disease: the insurer may treat the heart disease as existing before the policy started.
Large deductions for consumables, ICU and room rent on a long stay.
Critical illness policies: a fixed benefit for bypass is paid only if the surgery was actually done and meets the policy’s definition. Some also require you to survive a set number of days.
A pre-existing-disease clause that names heart disease as an excluded complication of blood pressure or diabetes declared when the policy began.

Rules that apply

Pre-existing disease: a condition counts only if it was diagnosed or treated within 36 months before the policy started. After 60 months of continuous cover, a claim can’t be contested for non-disclosure except for established fraud.
Room rent: a proportionate cut needs a room-rent limit in your policy, and many wordings keep medicines, implants, diagnostics and ICU charges out of it.

What decided these disputes

For non-disclosure, dated records of earlier heart disease or a previous procedure generally decided the case for the insurer. An entry in the discharge summary alone often did not.
Where the policy clearly excluded heart disease as a complication of a declared condition during the waiting period, that exclusion was applied as written.
Under critical illness covers, whether the illness or surgery met the policy’s own definition and conditions usually decided the outcome.

Questions people ask

Can the room-rent limit reduce ICU charges?

Many policy wordings exclude ICU charges from proportionate deduction. Check the room-rent and associated-expenses clauses in your policy.

Is minimally invasive or robotic bypass covered?

It is still bypass surgery. Robotic surgery is on IRDAI’s list of modern treatments that insurers should endeavour to cover, and any sub-limit must be stated in your policy wording.

Can I claim from both my health policy and a critical illness policy?

Usually, yes. A critical illness policy is a benefit policy that pays a fixed amount, and you can claim under all your benefit policies. Your health policy pays the hospital bill.
