Mediswitch Explained: How Medical Aid Claim Switching Works in South Africa

If you bill medical aids in South Africa, your claims almost certainly pass through a claims switch. Mediswitch is the name most practitioners know, and it is one of the reasons a claim submitted at 09:15 can come back with a response before your patient reaches the car park.

This is a neutral explainer. We build practice software, but nothing here depends on which system you run.

What a claims switch actually is

A switch is a clearing house sitting between thousands of practices and dozens of medical schemes and administrators. Instead of every practice building a connection to every scheme, everyone connects once to the switch, and the switch handles the translation, routing and responses.

In practice it does four things:

1. Validates the claim structure — member number, dependant code, practice number, ICD-10 codes, tariff codes.
2. Routes the claim to the correct scheme or administrator.
3. Returns a response — accepted, rejected, or accepted with reductions — usually in near real time.
4. Delivers remittance data later, when the scheme actually pays.

Mediswitch (part of Altron HealthTech) is the best known; other switches and bureau services operate the same way. Your practice software either talks to a switch directly or hands claims to a billing bureau that does.

How a claim actually travels

Consult → clinical note → codes (ICD-10 + tariff) → claim built in your PMS
      → claims switch → scheme / administrator → response (seconds)
      → payment run → remittance advice → reconciliation in your PMS

Two points in that chain cause most of the pain. The first is coding — a note that does not carry the right diagnosis and procedure codes produces a claim that gets rejected or reduced. The second is reconciliation — the remittance rarely matches the claim line for line, and someone has to work out why.

Why claims get rejected

The recurring causes are boringly consistent:

• Membership lapsed, suspended, or dependant code wrong
• Benefit exhausted, or the service falls outside the plan option
• ICD-10 code missing, invalid, or not supported by the procedure billed
• Tariff code not valid for your discipline or practice number
• Duplicate claim, or claim submitted outside the scheme''s time limit
• PMB or authorisation requirements not met

None of these are exotic. Almost all of them are catchable before submission if your software validates at capture instead of at month-end.

Real-time responses versus payment

A crucial distinction practitioners lose money on: an accepted claim is not a paid claim. Acceptance means the claim was structurally valid and reached the scheme. Payment happens on the scheme''s cycle, and the remittance may reduce lines, apply co-payments, or shift amounts to patient liability.

If your process stops at "accepted", you will discover shortfalls weeks later. That is why chasing patient-liability balances promptly matters more to cash flow than almost anything else — see our cash flow guide for the 30-day version.

What to check in your practice software

Whether you run GoodX, Healthbridge, NetPractice, HeroMed or a bureau, ask the same six questions:

1. Is switching included, or an add-on with per-claim fees? Get the per-claim cost in writing.
2. Does it validate before submission — member status, ICD-10 and tariff validity?
3. Are rejections shown as a worklist, or buried in a report someone must open?
4. Is remittance reconciliation automatic, partial, or fully manual?
5. Does it track patient-liability balances separately after remittance?
6. Can codes be generated from the clinical note, or does someone retype them?

That last question is where AI-native systems differ most. HeroMed Prime, our South African product, builds the invoice and codes from the clinical note itself and submits to schemes, then reconciles remittances — which removes the retyping step rather than reorganising it. Compare the local options honestly in HeroMed vs Healthbridge, HeroMed vs GoodX and HeroMed vs NetPractice.

If you are changing switch, software, or both
