1. Your name

2. Contact Number, including email ID, and address

3. Policy type and number

Address with a Formal Greeting

Mention the Purpose of the Letter

Write the purpose of your health insurance claim letter in a clear, concise way, mentioning the specific treatment. You can also mention the hospital name along with the hospitalisation dates from start to end date.

Monitor the Claim Status 

After submitting the request letter for a health insurance claim, do not forget to follow up with the insurer if you have not already heard back.
