There is fire, you can add on flood, physical dmg etc.

Almost standard, unless the insurance company see that you're purchasing a high sum, they can drop abit of price to compete. They have a rate book for each risk.

It's better to over insure than under insure because if it's under insured say the market value was found to be 0.5m that time and insurance is only 0.4% that will be lesser by 20% of the original insurance coverage so the insurance company will only compensate 80% of 0.4m

Fire insurance is main coverage for a building policy and from there you can add on other perils if necessary

Yeap provided all the building belong to the same company

For Shop, if it's landed, can take in about 70 - 80% of the value of the property as the sum assured. If it's not landed, then cover 100% of the value of the property.

You are wasting your money when over-insured.

Insurance will only compensate based on the market price of insured property.

But if one wants to insure 1.5 mil, and paying the premium based on 1.5 mil, I don't think insurance company will reject though. 

A good rule-of-thumb/guide to whether or not an admission/treatment is claimable (applies to day procedures as well):

1) There is a treatment done, and the treatment is medically necessary.
Examples: dengue, slip disc, cardiac arrest, broken bones, injury due to accident, organ transplant, all critical illnesses, etc.
Some cosmetic advertisements that I noticed on the radio recently are marketing their procedure as a "treatment" for freckles and/or dark spots. These are categorized under aesthetic procedures and are not claimable.

2) What constitutes an injury due to accident:
It is sudden, violent, and/or external impact.
Examples: I waving goodbye to my uncles and aunties. Smart sibling of mine slam the car door shut. My fingers broken.
Verdict: it is sudden, it is external impact. Claimable.

3) Majority of rejected claims are due to incomplete documents.
Example of documents: medical report, claim forms, original receipts, itemized billing, credit card deposit receipt (if applicable).

a. Unless it's required to be hospitalized by the doctor if it's deemed very serious then yes, otherwise, normal skin rash you can eat medicine and get well soon.

b.
Falls under Emergency Accidental Out-Patient Treatment, unless it's just some skin got removed then a cotton can be used to stop it, then nothing much you can claim and go back home.

The point is, if the injury is so light that some bandage can just solve the issue, why do you need to claim from the medical card ?

E.g you bump your leg into a chair and got a black and blue bruise, do you just solve it there and then or still head to the hospital ?

Then head to the hospital if it's continuously and you fill that you've poked more than just the outer nose. There is no hard and fast rule, just pure logic. Even if you feel that it's not serious but you need to head to the hospital to check thoroughly and end up the doctor said everything is fine, just gave him some plaster and medicine. Then you have to just pay for the plaster, medicine, consultation on your own.

If the doctor that you broke your nose or there is internal bleeding and he needs the ENT surgeon to have an X-Ray and he needs to be warded, then yes, you can claim for it.

AA: As long as the treatment is justifiable for a treatment at the hospital, it will be claimable.
Let me share with you my personal experience with a client: She was rushed to the ER, but GL was declined citing procedure can be done as an outpatient. So she paid and later on I proceed to process the claim for her.
All documentations were complete and the claim cheque was delivered few weeks later.
Client happy, I also happy.

BB: Maybe you want to turn it down a notch with the gold digging 
But if it was really serious and require stitches from your inner nostril membrane, technically it is a self-inflicted injury and rightly written in the policy self inflicted injury is excluded.
But you don't so straight arrow tell the doctor you gila korek la. I also dunno how to taichi this one... But you taichi with the doctor lah. Janji the doctor buys your story. 

P/S: Individual medical cards usually only cover hospitalization and not clinics.
But take for example you are holding a corporate card and it includes clinic visits. By cash you can bring the receipts back to your HR dept to process the claim. By medical card, it'll be charged straight through and you won't have to part with that RM50-55 for any period at all.

Did I do a good job at answering your questions/concerns? Let me know! 

If the surgery can be done as Day Care Surgery, it is better as it saves costs.

Most of the insurer is also able to provide the Letter of Authorization for Day Care Surgery if the surgery can be pre-planned.
