Asking your doctor for a letter for an insurance dispute: what it should cover

Ask your treating doctor for a short, signed and dated letter on the hospital's or clinic's letterhead that answers the insurer's stated reason in clinical facts — when the condition was first diagnosed, why admission was needed, or why the treatment could not be given as an outpatient. Give the doctor the insurer's exact words and your records, and ask for facts the doctor can stand behind, not a view on whether the claim should be paid.

A doctor's letter answers the facts behind the reason, so read the reason first. For a health claim, the insurer has to tell you, with reference to the specific policy terms, why it rejected or cut the claim. The letter you ask for should speak to those words, not to the claim in general.^[1]

What the letter should cover

• When the condition was first diagnosed: For a pre-existing disease rejection. The definition looks at diagnosis, or medical advice or treatment, within 36 months before the policy began, so a date — and the record it comes from — matters more than the name of the illness.^[2]
• Why admission was needed: The symptoms, the risk, and the monitoring or treatment that needed a hospital bed. Wordings such as New India's define hospitalisation by a minimum of 24 consecutive in-patient hours, with exceptions for listed procedures, so the doctor can say what care was given across that time.^[3]
• Why it could not be done as an outpatient: Where the insurer says the treatment could have been given in OPD, the clinical reason it could not.
• What an unclear line in the record meant: If the discharge summary says "known case of" something, what that was based on and when it was first noted — without rewriting the summary itself.
• The link to what was billed: That the procedure or medicine on the bill was the treatment for this condition.

How to ask

1. 1

   Give the doctor the insurer's exact sentence

   A copy of the rejection or settlement letter, with the reason marked.

2. 2

   Give the records

   Earlier prescriptions, test reports and the discharge summary, so the letter can refer to them by date.

3. 3

   Ask numbered questions

   For example: "1. On what date did you first diagnose this condition, and in which record? 2. Why was in-patient admission necessary on the date of admission?" Numbered questions get answers you can map.

4. 4

   Ask for the formalities

   Letterhead, date, signature and the doctor's registration number, so that anyone reading the letter can check who wrote it.

5. 5

   Send it with a covering letter

   Add it to your reply or grievance as a numbered enclosure, and keep a copy. See answering document requests.

What a doctor's letter cannot do

It does not change the policy wording. If treatment falls under an exclusion that is written into the policy, a letter about necessity does not move it out. What the letter can do is show that the facts the insurer relied on are wrong or incomplete.

Expect it to be weighed against other medical opinion. If the dispute reaches the Insurance Ombudsman, the Rules let the Ombudsman "obtain the opinion of professional experts" where a case needs it, so a clear, dated, record-based letter carries further than a general one.^[4]
