Section 80D vs Section 80DDB: The Difference Most Filers Get Wrong
TL;DR
- Section 80D is for health insurance premium paid; Section 80DDB is for actual medical treatment cost incurred for specified diseases.
- 80D limits: Rs. 25,000 (under-60) or Rs. 50,000 (senior citizen); 80DDB limits: Rs. 40,000 (under-60) or Rs. 1,00,000 (senior citizen).
- 80DDB applies to a defined list of diseases (cancer, AIDS, chronic renal failure, neurological diseases, haematological disorders, etc.).
- 80DDB requires a prescription from a specialist; 80D needs only a premium receipt.
- Both sections can be claimed in the same ITR for the same person; they do not overlap.
- Both are available only under the old tax regime for AY 2026-27.
What this means in plain terms
Filers often treat 80D and 80DDB as variations of the same deduction. They are not. Section 80D is a forward-looking deduction for premium you pay to insure against future medical events. Section 80DDB is a backward-looking deduction for the cost of treating specific illnesses that have already happened. The triggers are different, the limits are different, and the documents are different.
You can absolutely claim both in the same year. If you paid Rs. 22,000 mediclaim premium and also spent Rs. 60,000 treating your father's chronic kidney condition, you have separate claims under 80D and 80DDB. Some taxpayers leave 80DDB on the table because they assume "I already claimed 80D, that covers medical." It does not.
Side-by-side comparison
Purpose
80D rewards you for buying health insurance. 80DDB compensates you for out-of-pocket cost of treating named diseases. One is preventive, the other is curative.
Limit structure
80D is capped per family unit: Rs. 25,000 (under-60) or Rs. 50,000 (senior). 80DDB is per dependent: Rs. 40,000 (under-60 patient) or Rs. 1,00,000 (senior patient).
Eligible payments
80D covers premium, top-up premium, critical illness premium and preventive check-up. 80DDB covers actual medical treatment expense for a specified disease, supported by bills.
Who can be covered
80D: self, spouse, dependent children, parents. 80DDB: self or any dependent (spouse, child, parent, brother, sister of the taxpayer; HUF members for an HUF).
Document needed
80D: premium receipt from insurer. 80DDB: prescription in prescribed format from a specialist working in a hospital (Form 10-I no longer required from FY 2015-16; specialist prescription is sufficient).
The diseases covered under 80DDB
Cancer (malignant cancers)
Active treatment of malignant cancers is included. Prescription must come from an oncologist with a DM or equivalent qualification.
Chronic renal failure
Diseases requiring dialysis or kidney transplant. Prescription from a nephrologist (DM Nephrology).
Haematological disorders
Haemophilia and thalassaemia are specifically named.
AIDS
Treatment of full-blown AIDS qualifies, with prescription from a specialist.
Neurological disorders with 40% or more disability
Includes ataxia, dementia, dystonia musculorum deformans, motor neurone disease, hemiballismus, chorea, aphasia, Parkinson's disease.
How the deduction interacts with insurance recovery
Net of reimbursement
If a portion of the medical cost was reimbursed by your employer or insurer, the 80DDB deduction is limited to the net out-of-pocket amount. You cannot double-dip.
Example
If your father's cancer treatment cost Rs. 5 lakh and the insurer reimbursed Rs. 4.2 lakh, your out-of-pocket is Rs. 80,000. Since your father is a senior citizen, the cap is Rs. 1 lakh; you claim Rs. 80,000.
No reimbursement scenario
If you have no insurance and paid the full Rs. 5 lakh yourself, you claim Rs. 1 lakh (capped) for a senior patient or Rs. 40,000 for a non-senior patient.
A real example
Take Meera, 44, Rs. 30 lakh CTC, Bengaluru. Her father, 71, was diagnosed with Parkinson's disease in FY 2025-26 and the neurological disability has been certified at 50%. Meera also pays health insurance premium for her own family.
Claims for AY 2026-27 (old regime):
- Health insurance premium for self, husband and son: Rs. 23,500 paid by UPI. Section 80D self-spouse-children bucket: claim Rs. 23,500.
- Health insurance premium for parents (senior citizen floater): Rs. 38,000 paid by net banking. Section 80D parents bucket (seniors): claim Rs. 38,000.
- Preventive check-up for Meera and husband: Rs. 4,200 via UPI. Inside self bucket, total now Rs. 27,700 capped at Rs. 25,000.
- Father's Parkinson's treatment cost in the year: Rs. 1,80,000 paid by Meera. Insurance reimbursed Rs. 95,000. Net out-of-pocket: Rs. 85,000. Section 80DDB cap for senior patient: Rs. 1,00,000. Claim Rs. 85,000.
Total Section 80D claim: Rs. 25,000 + Rs. 38,000 = Rs. 63,000. Total Section 80DDB claim: Rs. 85,000. Combined deductions across 80D and 80DDB: Rs. 1,48,000.
At Meera's 30% marginal slab plus 4% cess, this saves her Rs. 46,176 in tax for the year. If she had assumed 80D covered her father's treatment costs as well, she would have missed Rs. 26,520 of tax saving (the 80DDB slice).
What to do this week
- List anyone in the family currently receiving treatment for a specified 80DDB disease in the last 12 months.
- Ask the treating specialist for a prescription mentioning the disease and the patient's name (no specific Form 10-I needed, but the prescription must be from a hospital-affiliated specialist).
- Net off any insurance reimbursement against the actual cost before computing the 80DDB claim.
- Note that 80D and 80DDB are independent; both go into Schedule VI-A separately.

FAQ
Can I claim 80DDB if the disease was diagnosed in an earlier year?
Yes, the deduction is on expense incurred in the relevant financial year, not on date of diagnosis. As long as you are bearing treatment cost in the current year for a specified disease, you can claim.
Does the disease list include diabetes or hypertension?
No. Common chronic conditions like diabetes, hypertension and asthma are not in the 80DDB list. Only the specified diseases (cancer, AIDS, renal failure, neurological disorders with 40%+ disability, haematological disorders) qualify.
What if I cannot get a prescription from a specialist?
Without a specialist's prescription naming the disease and the patient, 80DDB cannot be claimed. The Income Tax Department specifically asks for it during scrutiny.
Is Section 80DDB available under the new tax regime?
No, both 80D and 80DDB are unavailable under the new tax regime (115BAC) for AY 2026-27.
Can I claim 80DDB for myself if I am the patient?
Yes. The taxpayer themselves is eligible. The same caps apply based on the patient's age (Rs. 40,000 under-60, Rs. 1,00,000 if senior citizen).
Do dental treatment or physiotherapy costs count?
Only if they are part of the treatment for a specified 80DDB disease. Standalone dental or physio expenses are not eligible.
Does the prescription need to be renewed yearly?
A fresh prescription for each year of claim is the safer approach, especially for ongoing chronic conditions, to demonstrate the patient is still under specialist care.
