Critical Illness

A lump sum on the diagnosis of a listed illness, paid whatever the treatment costs and whether or not anything was spent.

Also calledCritical Illness Benefit · CI Rider

In shortA critical illness claim needs 9 documents, and the ground insurers most often rely on to reduce or refuse it is this: the diagnosis not meeting the policy's own definition, which is usually narrower than the word in ordinary use.

First thing, todayThe claim turns on the diagnosis meeting the definition in the policy, so collect the reports that establish it from the start.

Three deadlines

Tell the insurer now, not after the assessment.
Pre-authorisation, or intimation before a planned admission, and within the hours the policy allows after an emergency one.
Every document within the time the insurer asks for it.

An itemised hospital bill, an authorisation form and a health card. An illustration.

When you would claim

Diagnosis of an illness named in the policy's list
A procedure named in the list, once it has been carried out
Survival past the period the policy sets after diagnosis
A claim under a rider attached to a life or health policy

What insurers most often rely on

The diagnosis not meeting the policy's own definition, which is usually narrower than the word in ordinary use
Illness first diagnosed inside the waiting period
A pre-existing condition the insurer says was known
Survival period not completed
Reports that establish the date of diagnosis being missing

Most are answered by the treating doctor in a paragraph, once somebody asks for the right paragraph.

The documents

ask the hospital on the day

9 items. A hospital will hand you most of them on the day if you ask at the desk, and take three weeks over them if you ask in a month. Ask on the day.

Claim form and the policy schedule with the list of illnesses
The diagnosis, from the specialist, in the words the policy uses
Investigation reports that establish it, with the dates
Hospital records and the discharge summary, where there was admission
Treating doctor's certificate on the date of first diagnosis
Identity and age proof
Cancelled cheque and bank details in the insured's name, for the NEFT payment
Details of any other insurance covering the same illness
The benefit claimed, read against the policy’s own list of illnesses and the survival period it sets

Admission to dischargeThree dates and the gap between them is most of what a health insurer queries. Note the hour of the emergency admission too: several wordings count in hours, not days.

Cashless Health Claim Process: What to Do, and what it shares with this

The cashless procedure is the one to open, and it holds here even where no hospital is involved: tell the insurer inside the hours the policy allows, keep every original that is handed to you, and never let a discharge or a settlement happen before the outstanding query has been answered in writing.

Read the benefit table

This pays a benefit, not a loss. The capital sum insured and the policy's own table decide the figure, and no amount of receipts moves it. What is worth reading before a claim is which events are on that table and what each is worth.
