Health insurance claims in India often get delayed, reduced, or rejected—not always because of fraud. Many times, patients or families simply don’t know the rules, and hospitals do not explain them clearly.
This guide explains:
- Why each type of claim gets rejected or flagged
- Real-life examples
- How customers can be innocent
- What to do to prevent each issue
1. Pre-Existing Diseases (PED) Not Disclosed or Partially Disclosed
Why Claims Get Rejected or Flagged
Not declaring past diseases, medications, surgeries, or ongoing treatments leads insurers to flag the claim. Even conditions like high BP, diabetes, thyroid, asthma, anxiety, or frequent migraines must be disclosed.
Example
A person taking diabetes medication but not declaring it gets hospitalized for a heart issue. Insurer traces past prescriptions, flags non-disclosure, and rejects the claim.
How Customers Can Be Innocent
- They may not consider BP or thyroid as “diseases.”
- They forget old treatments from years ago.
- Agents sometimes ask them to sign blank proposal forms.
- They rely on hospital staff for form filling.
How to Prevent
- Disclose everything, even minor issues.
- Never sign blank proposal forms.
- Tell your advisor all past medical details.
- Keep old prescriptions as proof.
2. Waiting Period Not Completed
Why Claims Get Rejected or Flagged
Policies have multiple waiting periods:
- 30-day initial waiting period for illness
- 1–2 years for specific procedures
- 2–4 years for pre-existing diseases
- 9 months–2 years for maternity
Claims that fall inside these periods are not payable.
Example
A patient undergoes hernia surgery within 5 months of buying the policy; it still falls within the waiting period, so the claim is rejected.
How Customers Can Be Innocent
- They don’t understand waiting periods.
- They rely only on verbal explanations.
- Hospital staff claims “insurance will take care.”
How to Prevent
- Understand key waiting periods before buying.
- Consult your advisor before planned hospitalization.
- Buy the policy early to avoid long waiting times.
3. Non-Disclosure or Wrong Disclosure of Lifestyle & Medical Habits
Why Claims Get Rejected or Flagged
Incorrect information about smoking, alcohol consumption, obesity, or past surgeries can cause claim rejection when discovered during hospitalization.
Example
A smoker marks “Non-Smoker” on the form. Later, the discharge summary mentions “long-term smoker.” Insurer rejects the claim.
How Customers Can Be Innocent
- Agent marked details incorrectly.
- The customer quit smoking years ago.
- They do not know that even occasional smoking counts.
How to Prevent
- Verify every detail in the proposal form.
- Inform your advisor before signing the form.
- Update insurer records when lifestyle habits change.
4. Treatment Not Covered / Exclusions in the Policy
Why Claims Get Rejected or Flagged
Many treatments are excluded, such as:
- Cosmetic procedures
- Weight-loss surgeries
- Fertility treatments
- Experimental treatments
- Most dental treatments (unless accidental)
Example
A person undergoes bariatric surgery for weight reduction. It falls under exclusions; hence, the claim is rejected.
How Customers Can Be Innocent
- They aren’t aware of exclusions.
- Hospital incorrectly says “insurance will cover it.”
- They misinterpret marketing material.
How to Prevent
- Read the policy exclusions carefully.
- Confirm coverage with an advisor before planned procedures.
- Ask hospital for a justification letter for the treatment.
5. Incomplete Documentation
Why Claims Get Rejected or Flagged
Missing essential documents like discharge summaries, investigation reports, original bills, or prescriptions can lead to delay or rejection.
Example
Patient forgets to collect original reports in a hurry. Insurer cannot validate the diagnosis, resulting in claim rejection.
How Customers Can Be Innocent
- Hospitals fail to provide all documents.
- Family is stressed and forgets to collect them.
- Some reports may be misplaced by the hospital.
How to Prevent
- Assign one family member to manage documents.
- Ask for both physical and soft copies.
- Scan all documents after discharge.
6. Non-Medical Expenses Not Payable
Why Claims Get Rejected or Flagged
Non-medical items such as gloves, masks, admission kits, baby food, PPE kits, pulse oximeters, or thermometers are not payable under IRDAI’s non-medical list.
Example
Hospital charges for multiple PPE kits for each doctor round. Insurer deducts these non-payable items.
How Customers Can Be Innocent
- They assume insurance covers everything.
- Hospitals add non-medical items routinely.
- They are not aware of standard non-payable lists.
How to Prevent
- Ask the hospital to avoid unnecessary consumables.
- Review non-medical item charges.
- Buy add-ons like a “Non-Medical Expenses Cover.”
7. Room Rent Limit Breach or Choosing Unnecessarily Higher Room Categories (Even Without Capping)
Why Claims Get Rejected or Flagged
If a patient chooses a room above the policy limit, proportionate deductions apply. However, even if the policy has no room-rent capping, insurers may still flag cases where the patient chooses deluxe or suite rooms without medical justification or where the hospital inflates charges due to premium rooms.
Premium rooms often increase overall charges, including doctor fees, nursing charges, procedure costs, and service fees.
Examples
- Capped Policy: Policy covers ₹5,000/day, but patient selects ₹12,000/day. Proportionate deduction applies.
- No-Cap Policy: Patient selects a suite. Inflated charges lead to reduced claim after auditor review.
- Hospital Misguidance: Staff suggests premium rooms by saying “insurance will pay.” Costs rise unnecessarily.
How Customers Can Be Innocent
- Emergency admission with no room choices available.
- Hospital claims only premium rooms are empty.
- Family assumes no room-limit means everything is covered.
- They do not understand how billing varies by room category.
How to Prevent
- Always ask for standard rooms first.
- Request tariff charts across room categories.
- Avoid premium rooms unless medically necessary.
- Consult your advisor before confirming room.
- Even without capping, choose rooms reasonably.
8. Unnecessary Hospitalisation (Medically Not Required)
Why Claims Get Rejected or Flagged
If admission is not medically required, insurers reject the claim. This includes observation-only admissions, cases without active treatment, or mild conditions manageable on OPD basis.
Example
Patient with mild fever is admitted just for observation. No active treatment is given. Insurer rejects it as an OPD case.
How Customers Can Be Innocent
- Hospital recommends unnecessary admission.
- Family panics and agrees.
- Elderly patients often get admitted for safety.
How to Prevent
- Ask whether the admission is truly required.
- Ask the doctor to record medical necessity in notes.
- Take a second opinion for non-emergencies.
- Consult your advisor before agreeing to admission.
9. No Clear Diagnosis (Admission Only for Investigation)
Why Claims Get Rejected or Flagged
If hospitalization is done just for investigations without a diagnosis or treatment, insurers reject the claim. Tests alone do not justify admission unless there is a suspected diagnosis or a need for monitoring or IV treatment.
Example
Patient admitted for stomach pain. All tests normal. No treatment given. Discharged after two days. Insurer rejects because admission was purely for investigation.
How Customers Can Be Innocent
- Symptoms appear serious initially.
- Doctor suggests admission for detailed testing.
- Patient relies on doctor’s advice.
How to Prevent
- Ask whether tests can be done in OPD.
- Ensure the doctor mentions a suspected diagnosis.
- Maintain OPD records showing earlier attempts to treat.
10. Fraudulent or Inflated Billing by Hospitals
Why Claims Get Rejected or Flagged
Hospitals sometimes inflate charges, add unnecessary tests, or bill differently for insurance patients. Insurers perform audits and may uncover overcharging, unnecessary consumables, or inflated packages.
Example
Hospital bills ₹20,000 worth of consumables that normally cost ₹5,000. Insurer audits the bill and reduces the claim.
How Customers Can Be Innocent
- They trust hospital bills blindly.
- Hospital follows “insurance billing” structures.
- Family signs documents without reviewing thoroughly.
How to Prevent
- Compare package rates with non-insurance patients.
- Ask for detailed bill breakups.
- Question unnecessary tests.
- Keep all communication documented.

- Buy policies early to avoid long waiting periods.
