Inpatient Medicines Under GST: Composite Healthcare Cannot Be Split by Billing Format

When Hospital Billing Meets Composite Supply

The Calcutta High Court order in M/s. Narayana Hrudayalaya Limited Versus The Joint Commissioner of State Tax, Large taxpayer Unit & ORs. - 2026 (7) TMI 1261 - CALCUTTA HIGH COURT, raises an important GST issue for hospitals, tax officers and professionals advising the healthcare sector. The question is whether medicines, consumables and implants supplied to inpatients are part of exempt composite healthcare services or whether they become separately taxable merely because they are shown separately in the hospital bill and charged at MRP.

The petitioner operates a chain of multi-speciality hospitals and provides healthcare services. For inpatient treatment, the hospital issues a single bill covering consultations, bed charges, surgery, diagnostics, medications, consumables, and implants. Medicines are shown as separate line items and are 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 at this interim stage, the order is significant because it brings into focus two important GST principles: composite supply of healthcare services and the limited scope of Section 76.

Healthcare for Inpatients Is More Than a Bundle of Separate Items

In a hospital setting, inpatient treatment is not merely a collection of independent supplies. A patient admitted for treatment receives comprehensive medical care. Consultation, nursing, bed charges, diagnosis, surgery, medicines, implants and consumables are all part of the treatment process. The patient does not come to the hospital merely to purchase medicines. The primary purpose is healthcare.

This is where the statutory definition of 'composite supply' becomes 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, if different goods or services are supplied together in the ordinary course of business and one of them gives the supply its essential character, the entire transaction may be treated as a composite supply. In the case of inpatient treatment, medicines, consumables, implants, diagnostic tests, surgery, room facilities, and nursing care are not normally supplied separately. They are supplied together to provide healthcare. The principal supply is the healthcare service.

Section 8(a) of the CGST Act, 2017, provides the tax treatment 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 such a composite supply would ordinarily follow the tax treatment of the principal supply.

This formed the foundation of the petitioner's argument. The petitioner contended that inpatient healthcare is a composite supply under Section 2(30). Since the principal supply is a healthcare service and such service is exempt under Entry 74 of Notification No. 12/2017-Central Tax (Rate), medicines, consumables, and implants supplied as part of inpatient treatment should also remain exempt as part of the composite healthcare supply.

Separate Line Items Do Not Always Break a Composite Supply

The Department's case was that medicines were shown separately and charged at MRP. Accordingly, the Department held that the hospital had collected GST on medicines and was liable under Section 76. The petitioner countered that separate disclosure in the invoice does not automatically convert a naturally bundled healthcare service into separate taxable supplies.

This point is crucial. In modern billing systems, hospitals often show detailed line items for transparency, insurance processing, patient understanding and internal accounting. A line item may explain the components of a treatment bill, but it does not necessarily determine the tax character of the supply. The tax character depends on the real nature of the transaction, the dominant supply and the statutory concept of composite supply.

If every separate line item were treated as a separate supply, the concept of composite supply would lose much of its meaning. Composite supply exists precisely because different elements may be supplied together in the ordinary course of business. The law then identifies the principal supply and applies the tax treatment accordingly.

Therefore, the real question is not merely whether medicines appear separately in the invoice. The deeper question is whether, in the facts of inpatient treatment, medicines and consumables are naturally bundled with the healthcare service and supplied as part of the treatment.

Section 76 Is About Tax Collected but Not Paid

The Department invoked Section 76(1) of the CGST/WBGST Act. This provision addresses a specific situation. It applies where a person has collected any amount from another person as representing tax under the Act and has not paid it to the Government. In such a case, the amount must be paid to the Government, irrespective of whether the underlying supply is taxable.

The scope of Section 76 is therefore serious but limited. It is not a general charging provision. It does not, by itself, determine whether a supply is taxable. It is a recovery provision for amounts collected as tax but not deposited with the Government.

This distinction is central to the case. The petitioner submitted that it did not separately charge GST to inpatients. The fact that medicines were billed at MRP did not mean that GST was collected. According to the petitioner, MRP billing was part of its business policy and uniform pricing practice. Therefore, Section 76 could not be invoked unless the Department first established that an amount had actually been collected as representing GST.

The High Court noticed this controversy. At the interim stage, it recognised that the matter involved a conflict between exempt composite healthcare and the Department's allegation of a separate taxable sale of medicines.

MRP Billing Is Not Conclusive Proof of GST Collection

The petitioner relied on Deputy Commissioner of Commercial Taxes (Vigilance) Versus M/s Hindustan Lever Limited - 2016 (7) TMI 76 - Supreme Court. The Supreme Court in that case recognised that an assessee is entitled to carry on business and adopt a uniform market retail price. Uniform pricing may be applied across units, including both exempt and non-exempt, for commercial reasons.

The important principle from Hindustan Lever is that a market retail price stated to be inclusive of all taxes may serve as a starting point for examination, but it does not, by itself, prove that tax has been collected. Uniform pricing can arise from business policy. It may be adopted to avoid market distortion, prevent the flow of goods between States, maintain brand consistency, or simplify distribution. Therefore, tax collection cannot be presumed merely from uniform MRP.

This principle directly supports the petitioner's argument. If MRP billing is treated as conclusive proof of GST collection, many commercial pricing decisions may be misunderstood. Section 76 requires the collection of an amount representing tax. A price charged for medicines, even if it is the MRP, must be examined carefully before concluding that GST has been collected separately.

In the hospital context, this is even more sensitive. Patients may receive a consolidated inpatient bill containing several components. The presence of MRP against medicines does not automatically show that the hospital collected GST as a separate tax component. The invoice, billing practice, exemption entry and nature of supply must all be examined.

Spanv Medisearch Strengthens the Healthcare Composite Supply Argument

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 on the ground that medicines supplied as part of such composite service were billed at MRP and, therefore, tax was collected by the supplier.

This principle is significant because it addresses the same practical concern. Medicines supplied to inpatients are not always comparable to pharmacy sales to outpatients or walk-in customers. Inpatient medicines are part of medical treatment. If the healthcare service is a composite exempt supply, the Department must exercise caution before separating medicines solely because they are billed at MRP.

The reliance on Spanv Medisearch, therefore, gives the petitioner's case a direct foundation in the healthcare sector. It supports the view that the form of billing cannot automatically override the substance of inpatient healthcare.

The Petitioner's Own Mysore Order Shows the Complexity

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 in the Calcutta order shows how the Department analysed the issue 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). However, it also recorded the audit objection that medicines were billed separately on an MRP basis and shown separately in inpatient invoices. On that basis, the Department took the view that medicines were being sold separately and GST was collected.

This reference is useful because it shows that the issue is not merely theoretical. It has real administrative complexity. Hospitals may have detailed billing formats. Medicines may be separable in accounting records. Yet the legal question remains whether they are separate supplies for GST purposes or components of a composite inpatient healthcare service.

The Calcutta High Court has not finally resolved this issue in the interim order. But by granting protection and calling for affidavits, it has recognised that the matter requires deeper examination.

Alternative Remedy Did Not Prevent Interim Protection

The State objected that the writ petition was not maintainable because the impugned order was appealable. Ordinarily, High Courts are reluctant to interfere when a statutory appellate remedy is available. However, the existence of an appellate remedy does not automatically bar writ jurisdiction in every case, especially where the issue involves jurisdiction, statutory interpretation, or possible coercive consequences.

At the interim stage, the High Court did not finally decide on the issue of maintainability. It granted time to the State to file an affidavit-in-opposition and fixed the matter for further hearing. At the same time, it restrained the authorities from taking coercive steps or giving effect to the order dated 25.02.2026 till the next date.

This approach is balanced. It does not finally decide the taxpayer's claim. It also does not allow immediate coercive recovery on a disputed legal issue requiring careful examination.

Why the Interim Order Matters

Although the order is interim, it carries practical significance. It indicates that the question of GST on inpatient medicines cannot be decided mechanically by looking only at MRP billing. The issue requires consideration of composite supply, principal supply, the healthcare exemption, Section 76, and actual collection of tax.

The order also reminds the Department that Section 76 should not be used as a substitute for a detailed taxability analysis. Section 76 is triggered by the collection of an amount representing tax. Therefore, if the Department alleges that GST has been collected, it must show the basis for such a conclusion. Merely stating that MRP includes taxes may not be sufficient.

For hospitals, the order is a reminder to maintain clear billing language. Inpatient bills should avoid ambiguity. If GST is not charged separately on exempt healthcare services, the invoice should not create the impression that GST has been collected on exempt components. Internal accounting, patient communication, and invoice design should all be aligned with the tax position.

Healthcare Exemption Must Be Applied With Commercial Sense

GST law must be applied in a manner that reflects how healthcare actually functions. Inpatient treatment is not a retail transaction for medicines. Medicines and consumables are used because the patient is under treatment. They are administered as part of clinical care. Their purpose is not independent sale but medical treatment.

At the same time, hospitals must be careful. If there is a separate pharmacy sale to an outpatient or a walk-in customer, the tax treatment may be different. The present controversy concerns inpatient supply as part of healthcare service. Therefore, facts matter. The nature of patient admission, billing pattern, treatment package, supply chain and invoice wording will all be relevant.

This distinction between inpatient and independent medicine sale is likely to remain important in future GST disputes.

The Larger Message: Composite Supply Cannot Be Split by Billing Format Alone

The deeper principle emerging from this case is that a composite supply should not be split merely because components are shown separately in the invoice. Taxability should follow the real nature of the supply. If the principal supply is an exempt healthcare service and the incidental supplies are naturally bundled with it, separate line-item disclosure should not automatically change the character of the supply.

Similarly, Section 76 should be applied only where there is actual collection of an amount as tax. A price charged at MRP, or a price stated to be inclusive of all taxes, may invite examination, but it does not conclusively prove collection of GST.

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 adjudication. The case will be heard further on 03.09.2026.

For senior officers and professionals, the interim order offers a useful caution. Do not confuse MRP billing with tax collection. Do not confuse line-item disclosure with separate supply. And do not invoke Section 76 without first establishing that an amount was actually collected as representing GST.

In GST, form matters. But substance still leads.
