IPD Billing in Hospitals: Room Rent GST Rules Explained

Hospital room rent is where most billing software quietly goes wrong. The rule is short, but the edge cases — mixed stays, threshold crossings, ICU transfers — are where manual calculation fails. Here is the complete picture for IPD billing.

The ₹5,000 Rule in Plain Language

• Room rent ≤ ₹5,000 per day: GST exempt (0%).
• Room rent above ₹5,000 per day: 5% GST on the entire room charge — not just the excess.

That full-amount rule is the trap. A ₹5,200 room is taxed at 5% on ₹5,200, producing ₹260 — not 5% on the ₹200 excess. This rule has applied since 18 July 2022 and was not changed by the September 2025 GST 2.0 rate rationalisation; confirm the current notification with your CA before changing your tariff.

ICU Is Always Exempt

ICU, CCU and NICU charges are exempt regardless of amount — a ₹15,000/day ICU bed attracts no GST. Critical care is treated as essential healthcare, full stop.

Mixed Stays: Evaluate Day by Day

A five-day admission is not one tax event. Each day is evaluated independently, then consolidated at discharge.

The discharge invoice must show this split explicitly — exempt room days and taxable room days as separate lines, with the correct tax on the taxable portion.

Why 5% Without ITC Matters

The 5% rate is a without input tax credit rate. The hospital cannot claim ITC on the inputs attributable to that supply. Building it into your pricing model matters: a taxable luxury room is genuinely more expensive to provide than the headline rate suggests.

What Your Billing Software Must Do

1. Evaluate the threshold per room day, not per bill.
2. Hard-code the ICU/CCU/NICU exemption.
3. Apply 5% to the full amount the moment the threshold is crossed.
4. Consolidate correctly on the discharge invoice with exempt/taxable line separation.
5. Flow taxable room rent into GSTR-1 while exempt amounts land in the exemp schedule.

How the Discharge Bill Should Look

Show taxable and exempt lines separately and total the GST at the bottom. Confirm the treatment of medicines and consumables with your CA for your hospital’s billing structure.

FAQ

• Is the ₹5,000 limit per room or per patient? Per room per day, as charged.
• What about a room upgrade mid-stay? Each day follows its own room's rate — another reason day-by-day evaluation is mandatory.
• Are attendant charges taxable? Attendant services billed separately are outside room rent; treat per the nature of the service and your CA's advice.
