Mandatory Elements in a Valid Medical Bill in India

A compliant clinic invoice must include all of the following under GST law and consumer protection regulations:

  • Clinic name and address as registered
  • GSTIN (if annual turnover > ₹20 lakh)
  • Sequential invoice number — unique per financial year (e.g., CF/2026-27/001)
  • Invoice date
  • Patient name and address
  • Itemised services/medicines — each line item separately
  • SAC/HSN code for each service or medicine
  • Rate and amount for each item
  • GST rate and amount (CGST + SGST or IGST) — or "Exempt" for medical services
  • Total amount in words and figures
  • Authorised signatory

GST Invoice vs Bill of Supply — Which Does Your Clinic Need?

Document TypeWhen to UseGST Column
Tax InvoiceWhen billing taxable supplies (pharmacy, cosmetic procedures)Show GST amount
Bill of SupplyWhen billing only GST-exempt services (OPD consultation, lab tests)Write "Exempt under GST"
Consolidated InvoiceMixed bill with both exempt and taxable itemsShow exempt + taxable separately
ℹ️
Most Clinic Bills Are Bills of Supply
If your clinic only provides OPD consultations, diagnostics, and procedures — all GST-exempt — you issue a Bill of Supply, not a Tax Invoice. The format is nearly identical but says "Bill of Supply" and shows 0% GST. See our complete GST guide for clinics →

Frequently Asked Questions

Do I need to show "Nil GST" or "Exempt" on medical bills?

Best practice is to write "Exempt" alongside the SAC code 999312 for medical services. This satisfies any GST audit query and makes it clear the exemption is claimed correctly.

What invoice number format should I use?

Any unique sequential format is valid. Common formats: CF/2026-27/0001 (prefix/financial year/number). The number must reset each financial year and cannot have gaps.

Can I give a handwritten medical bill?

Technically legal but strongly inadvisable. Handwritten bills make GST reconciliation, insurance claims, and audits very difficult. Digital bills take 10 seconds with clinic software.
