Buying medical insurance online is usually simple, but delays happen when personal details do not match official records or when health information is incomplete.
Whether you are purchasing a mediclaim policy or a broader health insurance plan, the document requirement is typically simple.
If you keep the required documents and key details ready before you start, you can fill out the application accurately and complete the purchase without follow-ups.
In this guide, we outline the essential documents and information you should keep handy, including what to prepare when you are buying cover for elderly parents.
Documents You Typically Need for Purchase
Keep basic KYC and nominee details ready so you can complete the application in one go without delays.
Identity Proof
A clear copy of a government-issued photo ID is usually required for verification. Keep one primary ID ready and ensure the name spelling matches what you will enter in the proposal form.
Address Proof
Insurers commonly require valid address proof. If your address has recently changed, keep the latest supporting document ready, so your policy is issued with the correct communication address.
Age Proof
Date of birth matters for eligibility and pricing. Many IDs already serve as age proof. The key is consistency across records.
Photograph and Contact Details
Keep a recent photograph (digital is also fine) and ensure your mobile number and email ID are active. Policy documents and updates are typically sent to the registered contact details, so a typo here can create avoidable hassle.
Duly Filled Proposal Form
This is the primary application form provided by the insurer, containing your personal details and desired coverage options.

Health Information That Helps Avoid Follow-Up Queries
Even when document upload is minimal, your health disclosures must be accurate. Keeping a small health file helps you answer questions confidently.
Current Prescriptions and Ongoing Medication
If you or any member is on long-term medication, keep prescriptions handy. This supports accurate disclosure and reduces confusion about conditions and treatment history.
Existing Diagnosis and Past Procedures
If there has been a diagnosed condition, surgery, or ongoing treatment, keep any relevant reports or discharge summaries available. You need the key records that confirm the timeline and nature of treatment.
Previous Policy Details
If you are moving from an older plan to a new one, keeping the previous policy copy can help you fill in details correctly and maintain your own records for continuity.
If You are Buying Cover for Your Family
When you compare the best health insurance options for a household, you will usually add multiple members under one proposal. Keep these details ready for each person:
- Full name as per ID
- Date of birth
- Relationship to proposer
- Any known medical condition and ongoing medication (if applicable)
This avoids errors like incorrect dates, missing middle names, or incomplete member information, which can slow down issuance.
If You are Buying Health Insurance for Senior Citizens
Senior proposals often need more careful health disclosure because medical history is more relevant to underwriting. For health insurance for senior citizens, keep these ready:
Medical History Summary
Write down diagnosed conditions, previous hospitalisations, and any recurring symptoms that have required doctor visits.
Medicine List and Doctor Details
A simple list of current medicines and the treating doctor’s name/hospital can help you fill out health questions accurately without assuming.
Recent Reports, You Already Have
If your parents have recent test reports or consultation notes, keep them ready. Insurers may ask for medical information depending on age and health profile, and having existing records can prevent delays.

What to Save Immediately After Purchase
Once you complete payment and the policy is issued, save these documents in one folder:
- Policy schedule and policy wording.
- Premium receipt/payment confirmation.
- E-card or digital policy copy (if provided).
- Any email confirmations or endorsements.
It ensures you can access your policy quickly during hospital admission, renewal, or if you need to raise a service request.
Common Mistakes That Create “Hassle” During Purchase
These are minor issues, but they are the most common reasons applications get stuck:
- Name or date of birth does not match the ID proof.
- Incorrect email/mobile number, leading to missed OTPs or policy delivery issues.
- Unclear scans or cropped documents.
- Skipping disclosure of ongoing conditions or long-term medication.
- Entering a temporary address without supporting proof.
A careful five-minute check before submission saves much more time later.
Final Thoughts
To buy medical cover without friction, focus on accuracy and readiness. Keep your ID, address, age proof, nominee details, and basic health records organised.
This applies whether you are purchasing a simple mediclaim policy or a broader health insurance plan, and it becomes even more critical when arranging cover for seniors. With the proper documents ready, your purchase stays smooth, quick, and easy to manage later.
