Rejected as “not medically necessary”?

How most policies define it

IRDAI’s 2020 standard definitions were repealed as regulation in 2024, but most policy wordings still use them. Medically necessary treatment is typically defined as treatment that:

• is required for the medical management of the illness or injury;
• does not go beyond the level of care needed for safe, adequate and appropriate care;
• is prescribed by a medical practitioner;
• conforms to accepted professional standards of medical practice.

When the rejection is weak

• Your treating doctor advised admission, and the discharge summary records the symptoms, findings or risks that led to it.
• The treatment needed monitoring, IV medication or a procedure that couldn’t safely be done at home or as OPD.
• The insurer’s reason is a general remark like “could have been managed as OPD”, with no clause and no medical reasoning. A rejection must cite the specific policy terms, and a committee of the insurer must approve every repudiation.

When the insurer is likely right

• The stay was mainly for tests or evaluation, with no active treatment, and your policy excludes that.
• The records show no symptoms or findings that needed in-patient care.

What to do

1. Ask your treating doctor for a short letter explaining why admission was needed at the time.
2. Collect the discharge summary, case sheet, vitals and test reports that show your condition on admission.
3. Write to the Grievance Redressal Officer with these, quoting the policy’s definition, then go to the Insurance Ombudsman if needed.
