GST on hospital bills in India: when you're being wrongly charged
The full guide to GST on Indian hospital bills — what's exempt under Notification 12/2017, the ₹5,000/day room-rent rule from Budget 2022, the ICU carve-out, and how to spot the four most common GST overcharges.
Published · Jaanch
If your hospital bill from this year has a "GST" or "CGST + SGST" line on it, there is a decent chance some part of it is wrong. The rules around GST on healthcare in India are narrower than most billing departments realise, and the exemptions are easy to miss. This post walks through what is actually exempt, what isn't, and the four overcharge patterns we see most often when auditing real bills.
The headline rule: healthcare services are GST-exempt
The single most important notification to know is Notification 12/2017 — Central Tax (Rate), entry 74. It exempts services provided by a "clinical establishment, an authorised medical practitioner or paramedics" from GST.
In plain English, when you are admitted to a hospital and treated, none of the following attracts GST:
- Doctor and specialist consultation
- Surgery, anaesthesia, and operation theatre charges
- Nursing care, ICU care, room stay
- Diagnostic tests (pathology, radiology, imaging)
- Physiotherapy, dialysis, blood transfusion
- Cardiac catheterisation, endoscopy
- Patient food and ambulance, when bundled with treatment
The Government of India has chosen to treat healthcare as a public-good service. The exemption is broad on purpose. If your bill is charging GST on any of the above as a free-standing line, that is the first thing to question.
The two carve-outs you need to know
The exemption is not unlimited. Two specific carve-outs put GST back on the bill in specific situations:
1. Cosmetic and plastic surgery — 18%
Cosmetic surgery, plastic surgery (where it is not reconstructive), hair transplants, and cosmetic dental procedures are not exempt. They attract GST at 18% under the standard service rate. The legal reference is the proviso to entry 74 itself, which lists "cosmetic or plastic surgery" as an exclusion. Reconstructive surgery (post-burns, post-cancer, congenital defects) does remain exempt.
2. Room rent above ₹5,000 per day — 5%
Until July 2022 every hospital room was exempt. Budget 2022 added a sub-tax via Notification 3/2022 — Central Tax (Rate), effective 18 July 2022:
Room rent (excluding ICU/ICCU/CCU/NICU) above ₹5,000 per day per patient attracts 5% GST.
The threshold is per-day, per-patient, and applies only to the room charge — not the medicines, procedures, or nursing care given inside that room. The ICU carve-out is unconditional: ICU/ICCU/CCU/NICU stays remain fully exempt no matter what the per-day rate is. We've written a separate explainer on the ₹5,000/day room rent rule with worked examples.
What about medicines and implants?
This is where most billing departments get confused. The rule is:
- Inpatient medicines and implants — bundled with treatment as part of a composite supply. They ride the healthcare-services exemption. No GST. This is the position upheld in Servo Packaging and subsequent Authority for Advance Ruling decisions.
- Outpatient pharmacy sales — treated as separate goods supply. GST applies at the rate the medicine's HSN code attracts.
For the outpatient case, the rates that matter most:
| Category | Typical GST | Notification |
|---|---|---|
| Insulin and insulin analogues | 5% | Notification 1/2017 Schedule I |
| Oral rehydration salts (ORS) | 5% | Schedule I |
| Anti-cancer, anti-TB, anti-malaria, anti-HIV drugs | 5% | Schedule I (specified life-saving) |
| Vaccines, antisera, diagnostic kits (HIV / hepatitis) | 5% | Schedule I |
| General medicines (antibiotics, BP, diabetes, painkillers, steroids) | 12% | Schedule II |
| Surgical sutures, dressings, gauze | 12% | Schedule II |
| Examination and surgical gloves (HSN 4015) | 12% | Schedule II |
| Coronary stents, IOLs, hearing aids, pacemakers, joint implants | 5% | Schedule I (concessional medical-device slab) |
| Most other medical devices (HSN 9018–9020) | 12% | Schedule II |
| Cosmetic surgery | 18% | Schedule III (proviso) |
| Hospital administrative fees | 18% | Notification 11/2017 |
The four overcharge patterns we see
Across the real bills our audit engine has processed, the GST errors group into four patterns:
Pattern 1 — GST on inpatient services
The simplest mistake: 5% or 18% applied to consultation, surgery, anaesthesia or nursing during an inpatient stay. These should be ₹0. We see this most often on bills from smaller and mid-tier hospitals where the GST module is configured for outpatient billing and not switched off when a patient is admitted.
Pattern 2 — GST on room rent at or below ₹5,000/day
The threshold is widely misunderstood. We've seen bills charge 5% GST on a ₹2,500-a-day general ward — that's wrong. Below the threshold, non-ICU room rent stays fully exempt. The patient is owed a refund of the entire GST column.
Pattern 3 — GST on ICU stays at any rate
The ICU exemption is unconditional. We've seen bills run a ₹14,000-a-day ICU stay through the 5% slab on the assumption that "any room above ₹5,000 is taxable". That misreads the notification. ICU/ICCU/CCU/NICU are exempt regardless of cost.
Pattern 4 — Wrong GST slab on outpatient medicines
When a hospital pharmacy bills an outpatient — say a discharge prescription filled at the in-house counter — they need to pick the correct slab from the CBIC schedule. We've seen 12% applied to insulin (should be 5%) and 18% applied to plain antibiotics (should be 12%). Each of these is verifiable against the HSN code printed on the bill.
How to verify GST on your own bill
You don't need our tool to run a basic check. The Central Board of Indirect Taxes & Customs (CBIC) publishes the canonical rate notifications. The fastest sanity checks:
- Identify the line. Is the charge for a healthcare service consumed during an inpatient stay? If yes, the expected GST is ₹0. Any non-zero figure is a question worth asking.
- For room rent, check both whether you were in ICU (any rate → exempt) and whether the per-day amount crosses ₹5,000 (only the amount above the threshold concept doesn't apply — the entire room charge is taxed if it's above the threshold; nothing is taxed if it's at or below).
- For outpatient medicines, locate the HSN code on the bill (4–8 digits, usually 3001–3005 for pharmaceuticals or 9018–9022 for devices) and match it against the CBIC schedule. Insulin, oral rehydration salts, and life-saving drugs are 5%; most general medicines are 12%.
Asking for a correction
If you spot a GST overcharge, the polite first step is a written request to the billing desk before discharge — they can usually issue a corrected invoice on the spot. If the bill has already been settled, ask for the overcharge as a refund and reference the relevant notification number:
- Inpatient healthcare services exempt: Notification 12/2017 — Central Tax (Rate), entry 74
- Room rent threshold: Notification 3/2022 — Central Tax (Rate), w.e.f. 18 July 2022
- ICU exemption: same notifications, ICU exclusion preserved
- Medicine HSN rates: Notification 1/2017 — Central Tax (Rate)
The patient-side strategy is to anchor every dispute in the specific notification number. Once the billing desk sees you've identified the applicable rule, the conversation usually moves quickly. If it doesn't, our how to dispute a hospital bill guide covers the escalation path.
A note on framing
We deliberately avoid the word "fraud" in any audit output and in our explainers. Most GST overcharges on Indian hospital bills are configuration errors and stale templates, not deception. The bill correction is a procedural matter, and the language that gets you a refund fastest is procedural too: "the applicable notification exempts this service" rather than "you are cheating me".
