The Real Question Behind a Hospital Bill
The Calcutta High Court order in M/s Narayana Hrudayalaya Limited v. The Joint Commissioner of State Tax, Large Taxpayer Unit and Others, 2026-VIL-709-CAL, WPA 11903 of 2026, dated 14.07.2026, brings a significant GST controversy in the healthcare sector into sharp focus. The dispute is not merely about medicines. It concerns how GST law should treat inpatient treatment when a hospital bill separately shows medicines, consumables and implants.
The petitioner operates a chain of multi-specialty hospitals and provides healthcare services. For inpatient treatment, the hospital issues a single bill covering consultation, bed charges, surgery, diagnosis, medicines, consumables and implants. Medicines are shown as separate line items and billed at MRP. The GST authorities passed an order dated 25.02.2026, demanding GST under Section 76(1) of the CGST/WBGST Act on medicines and consumables supplied to inpatients.
The matter has not yet been finally decided. The High Court has granted interim protection and restrained the authorities from taking coercive steps or giving effect to the impugned order till the next date of hearing. The matter has been directed to be listed on 03.09.2026. Even as an interim order, the case is important because it places three connected ideas at the centre: composite supply, healthcare exemption and the limited role of Section 76.
Inpatient Treatment Has One Dominant Character
Inpatient treatment is not normally a loose collection of independent supplies. A patient admitted to a hospital receives an integrated medical service. The treatment may involve doctors, nurses, surgery, diagnosis, room facilities, medicines, implants and consumables. But the patient's essential purpose is not to buy goods from a pharmacy. The essential purpose is to receive healthcare.
This is why the concept of composite supply is important. Section 2(30) of the CGST Act, 2017 defines composite supply as a supply made by a taxable person to a recipient consisting of two or more taxable supplies of goods or services or both, or any combination thereof, which are naturally bundled and supplied in conjunction with each other in the ordinary course of business, one of which is a principal supply.
In simple terms, where different goods or services are supplied together in the ordinary course of business and one of them gives the transaction its essential character, the transaction may be treated as a composite supply. In inpatient treatment, medicines, consumables, implants, diagnostic services, nursing care and room facilities are ordinarily supplied together to provide healthcare. The principal supply is the healthcare service.
Section 8(a) of the CGST Act then provides the tax rule for composite supplies. It states that the tax liability on a composite supply comprising two or more supplies shall be determined as if the supply were that of the principal supply. Therefore, if the principal supply is an exempt healthcare service by a clinical establishment, the incidental supplies forming part of that composite supply would ordinarily follow the tax treatment of the principal supply.
This was the foundation of the petitioner's case. Since healthcare services by a clinical establishment are exempt under Entry 74 of Notification No.12/2017-Central Tax (Rate), medicines, consumables and implants supplied as part of inpatient treatment should not be carved out and taxed separately merely because they are visible in the invoice.
Billing Transparency Cannot Rewrite the Nature of Supply
The Department's case rested substantially on the fact that medicines were shown separately and charged at MRP. According to the Department, this showed that the hospital had made a separate taxable supply of medicines and had collected an amount representing GST.
The petitioner's answer was equally direct. Showing medicines separately in the bill does not automatically split a naturally bundled healthcare service. Modern hospital bills are detailed for many reasons, including insurance claims, internal accounting, patient transparency, audit controls, package analysis, and regulatory requirements. A line item explains the bill. It does not necessarily determine the legal nature of the supply.
This distinction is critical. If every line item in a composite transaction is treated as a separate supply, the doctrine of composite supply becomes weak. The very purpose of Section 2(30) and Section 8(a) is to deal with transactions where several elements are supplied together and one principal supply gives the transaction its real character.
Therefore, the legal question is not whether medicines are itemised. The question is whether they are supplied independently as goods or as part of inpatient healthcare. In the case of admitted patients, medicines and consumables are ordinarily used under medical supervision as part of treatment. That factual setting cannot be ignored.
Section 76 Cannot Run Without Actual Tax Collection
The Department invoked Section 76(1) of the CGST/WBGST Act. This provision addresses a specific situation. It applies where a person collects any amount from another person as representing tax under the Act and fails to pay it to the Government. In such a case, the amount must be paid to the Government even if the underlying supply is not taxable.
Section 76 is therefore a serious recovery provision, but it has a defined entry point. The Department must show that an amount was collected as representing GST. Section 76 is not a general charging section. It does not, by itself, determine whether medicines supplied to inpatients are taxable. It is triggered only where tax has actually been collected and not deposited.
This is why the petitioner emphasised that no GST was separately charged to inpatients. The hospital may have billed medicines at MRP, but, according to the petitioner, MRP billing was a commercial policy and not the collection of GST as tax. Therefore, unless the Department establishes the actual collection of an amount as representing GST, Section 76 cannot be applied merely on assumption.
The High Court noticed this controversy and granted interim protection. The order recognises that there is a live conflict between the petitioner's composite healthcare argument and the Department's separate taxable medicine-supply argument.
MRP Is a Price Marker, Not Automatic Evidence of Tax Collection
The petitioner relied on Deputy Commissioner of Commercial Taxes v. Hindustan Lever Limited, Civil Appeal No. 656 of 2008, decided on 30.06.2016, reported as (2016) 3 SCC 704 = 2016-VIL-35-SC. The Supreme Court recognised that a business may adopt uniform market retail prices for commercial reasons. Uniform pricing may apply across units, products, or territories, even where tax treatment differs.
The underlying principle is simple. A market retail price, even if stated to be inclusive of taxes, may be a starting point for enquiry, but it does not, by itself, prove that tax has been collected. Uniform pricing may reflect business policy. It may avoid market distortion, prevent the movement of goods from lower-tax to higher-tax areas, maintain consistency, or simplify commercial operations.
This principle is highly relevant to the hospital dispute. If MRP billing is automatically treated as GST collection, pricing practice will be confused with tax collection. Section 76 requires something more specific. It requires the collection of an amount as representing tax. Therefore, invoice structure, wording, the tax column, patient communication, and the nature of supply must be examined before alleging that GST was collected.
In the inpatient setting, the point is even stronger. A patient may receive a consolidated treatment bill. The fact that medicines are shown at MRP does not automatically mean that GST was separately collected on those medicines.
Healthcare Composite Supply Finds Support in Spanv Medisearch
The petitioner also relied on the Division Bench judgment in Spanv Medisearch Lifesciences Pvt. Ltd., Nagpur through its representative v. Union of India and Another, Writ Petition No. 2985 of 2026, decided on 10.04.2026. In that case, it was held that once composite healthcare services by a clinical establishment are exempt, proceedings could not be initiated merely because medicines supplied as part of such composite service were billed on an MRP basis and, therefore, tax was allegedly collected.
This judgment directly supports the healthcare-sector argument. Medicines supplied to inpatients are not necessarily comparable with counter sales by a pharmacy. Inpatient medicines are connected with diagnosis, treatment, surgery, or recovery. They are administered or consumed as part of medical care. If the healthcare service is the principal exempt supply, the Department must be cautious before separating medicines solely on the basis of MRP billing.
The reliance on Spanv Medisearch therefore gives the petitioner's stand a strong judicial foundation. It supports the proposition that billing format should not overpower the substance of inpatient healthcare.
The Mysore Order Shows Why Facts Matter
The petitioner also referred to an order dated 13. 10. 2025 passed by the Additional Commissioner of Central Tax, Mysore CGST Commissionerate, in its own case. The extract reproduced before the Calcutta High Court shows that the issue had already arisen in another jurisdiction.
That order recognised that the taxpayer was a clinical establishment providing healthcare services classifiable under SAC 9993 and eligible for exemption under Sl. No. 74 of Notification No. 12/2017- Central Tax (Rate). At the same time, it recorded the audit objection that medicines were billed separately at MRP and shown separately in inpatient invoices. On that basis, the Department took the view that medicines were sold separately and GST was collected.
This reference is important because it highlights the factual complexity of the issue. Hospitals may itemise medicines for accounting and transparency. The Department may treat such itemisation as evidence of a separate sale. The taxpayer may treat it as part of composite healthcare. The final answer depends on a careful examination of documents, billing practices, treatment structure and statutory provisions.
The Calcutta High Court did not finally decide this issue at the interim stage. It called for affidavits and protected the petitioner from coercive action. That approach reflects the seriousness of the controversy.
The Appeal Remedy Did Not End the Writ Protection
The State objected to the writ petition on the ground that the order was appealable. Generally, High Courts do not interfere where a statutory appellate remedy exists. However, this rule is not absolute. Writ jurisdiction may still be invoked where the dispute raises questions of jurisdiction, statutory interpretation, natural justice or serious coercive consequences.
At this stage, the High Court did not finally decide the maintainability issue against the petitioner. Instead, it allowed the State time to file its affidavit- in- opposition and directed the matter to be listed on 03.09.2026. In the meantime, it restrained the authorities from taking coercive steps or giving effect to the order dated 25.02.2026.
This is a measured interim approach. It does not grant final relief to the petitioner. It also prevents immediate enforcement of a demand founded on a contested interpretation of composite supply and Section 76.
Hospitals Need Clean Invoices, Not Confusing Signals
The order also carries an important compliance message for hospitals. If the hospital's position is that inpatient healthcare is an exempt composite supply, the billing format should support that position. The invoice should not create the impression that GST has been separately charged on medicines forming part of inpatient treatment.
Hospitals should review invoice descriptions, tax columns, patient communication, package structure and internal accounting classification. If GST is not charged separately on exempt inpatient healthcare, that position should be clear from the bill. Ambiguous invoice language can lead to avoidable litigation.
At the same time, one must distinguish inpatient treatment from independent pharmacy sales. A sale of medicines to an outpatient or walk-in customer may stand on a different footing. The present controversy concerns medicines, consumables and implants supplied to admitted patients as part of healthcare service.
This factual distinction is likely to be central in future GST disputes as well.
The Interim Order Matters Because It Slows Down Presumption
Although the order is interim, it matters because it slows down a possible presumption. The Court did not accept, at this stage, that MRP billing automatically proves collection of GST. It also did not permit coercive enforcement of the demand before the issue is examined in detail.
For the Department, the order is a reminder that Section 76 must be invoked with care. The Department must establish collection of tax as tax. Merely pointing to MRP or separate line items may not be enough. The composite supply argument must be addressed.
For taxpayers, the order is a reminder that legal position and billing practice must speak the same language. A strong composite supply argument may weaken if the documents suggest an independent sale or separate tax collection.
Composite Supply Must Lead, Not Invoice Appearance
The broader principle emerging from the case is that GST treatment should reflect the real nature of the supply. If inpatient healthcare is a composite supply and healthcare is the principal exempt supply, itemised medicines should not automatically be treated as separate taxable supplies. Billing format is relevant but not conclusive.
Similarly, Section 76 should not be stretched beyond its purpose. It applies to tax collected but not paid to the Government. It is not a shortcut to treating every MRP-based billing component as tax collection.
The final decision in Narayana Hrudayalaya will be important for the healthcare sector. For now, the Calcutta High Court has protected the petitioner from coercive action and kept the matter open for detailed consideration. The next listing is on 03.09.2026.
For senior officers and professionals, the caution is clear. Do not confuse itemisation with separate supply. Do not confuse MRP with tax collection. Do not use Section 76 unless the collection of an amount as GST is clearly established. In GST, the invoice matters, but the substance of the supply matters more
