THE ESSENTIALS
Before you start
- Read the document type.
- Link invoice and payment.
- Check references and amounts.
Read the document type
Hospital da Luz Guimarães explains that an invoice may require payment evidence to function as a receipt in a request to a funding organisation. This is the provider’s documentary guidance. The insurer should confirm requirements for the actual claim and the submission channel being used.

Link the records without duplicating the expense
Fictional example: Sofia receives an invoice by email and pays several days later. She keeps the invoice and matching receipt under the same reference. Her claim concerns one expense supported by two documents, rather than two medical services. If only a card transaction is visible, she asks the provider for the appropriate record.
Carry out a simple check before submitting
Check readability, service identification, date, amount and the link between invoice and receipt. Do not edit an image to fix errors; request correction from the issuer. Keep the final version so a replaced document is not submitted again. Read RMACHADO GROUP’s health guide to organise the practical requirements for using your policy.
