Bill a medical aid without opening a second package.

For psychologists, therapists and health practices

The fields a practice actually needs are part of the invoice, not an add-on you pay for separately. Everything works on a phone, between sessions, whether or not there is signal.

What practice admin usually costs you

  • Claims rejected over a missing or mistyped code.
  • Invoicing a parent for a child, and the scheme rejecting the name.
  • Two systems: one for notes, one for money.
  • Admin that waits until after hours because the day was full.

How it works

  1. The codes are on the invoice line

    Search ICD-10 by code or description and attach it to a line, with tariff and NAPPI alongside. The client record holds the scheme, plan and membership number, and they pull through automatically.

  2. Bill the payer, name the person seen

    Link a dependent to their main member and the invoice goes to whoever pays while still naming the person who was seen. That distinction is why schemes reject invoices, and it is handled for you.

  3. Capture between sessions, signal or not

    SizaBill installs on your phone and keeps working offline. Create an invoice with no reception and it syncs when you reconnect, so nothing waits for the evening.

What is built in

  • ICD-10 diagnosis codes with search, plus tariff and NAPPI codes per line
  • Medical aid scheme, plan and membership number on the client record
  • Main member and dependent billing, so the payer and the patient can differ
  • POPIA consent recorded automatically, with a dated history each client can see
  • A read-only login for your accountant, with every medical code hidden from them
  • VAT worked out the way a SARS tax invoice needs it

Your clients’ medical detail stays yours

An ICD-10 code is a diagnosis, which POPIA treats as special personal information. It never leaves your practice: it is stripped from your accountant’s screen, from every document they download, and from the CSV exports entirely.
