You can provide healthcare data as [line item data for an order](https://developer.mastercard.com/mastercard-gateway/documentation/gateway-features/trans-enrich-data/order-and-line-item-data/index.md). Healthcare data includes item details for healthcare purchases such as approved vision, dental, prescription, or other (clinic-related purchases). Provide this data only if it applies to you, and is accepted by your acquirer.
Alert: Healthcare data is supported from Mastercard Gateway API version 36 and later. Alert: Healthcare purchases must be made using the payer's Health Benefit card. Currently, the Mastercard Gateway only processes US Healthcare data using IIAS (Inventory Information Approval System). Based on your acquirer, a healthcare-specific Merchant Category Code (MCC) may need to be configured on your merchant acquirer link with the Mastercard Gateway. For more details, contact your payment service provider.

If you are required to submit healthcare data, you must provide all of the following information about the healthcare item in the transaction.

* Industry category: Supported industry categories are: HEALTHCARE_VISION, HEALTHCARE_DENTAL, HEALTHCARE_PRESCRIPTION, or HEALTHCARE_OTHER.
* Category (optional): The sub-category for the industry category. For example, prescription glasses for HEALTHCARE_VISION
* Item Name
* Item Unit price
* Item Quantity
* Item Unit Tax Amount

The Mastercard Gateway sends the sum of the amounts for all the line items having the same industry category, to the acquirer. The amount of a line item is: (Item Unit Price + Item Unit Tax Amount) \* Item Quantity. Only one record for each industry category will be sent to the acquirer.

The sum of all the industry category values will be sent as the item amount for the order. If the order amount differs from the item amount, the transaction will decline.

Healthcare data can be submitted in Authorize, Pay, Capture, and Refund transactions.
