Dr Derek Ackermann is a neurosurgeon practising at Mediclinic George. The rooms details below come from the Mediclinic practitioner listing, which is the hospital group own record of the specialists accredited to practise at its facilities, rather than from a third-party medical directory.

Official contact channels

Both numbers are rooms lines rather than personal ones, and no email address is published for the practice, so the telephone is the route for appointments, results and account queries alike.

One number on the same page is not the rooms and should not be used as though it were. The 084 124 line that appears across Mediclinic pages is the ER24 emergency number for the hospital group. It is the right number in an emergency and the wrong one for booking an appointment.

What this organisation provides

The practice is a neurosurgical one, and the listing records that Dr Ackermann practises at Mediclinic George and at Mediclinic George Day Clinic. The professional credentials published alongside it are worth noting down:

Those two numbers do different jobs and both are useful. The HPCSA registration number lets you confirm with the Health Professions Council of South Africa that the practitioner is registered and in good standing, which is a check worth making before any surgical procedure. The practice number is what a medical scheme needs in order to process a claim, and a specialist who cannot supply one cannot be claimed for.

Address and operating information

The rooms are inside Mediclinic George at Room 115, 2 Heron Street. No consulting hours are published on the listing, so establish them when booking rather than arriving on spec.

Specialist practices commonly work on referral, so check when you call whether a referral from a general practitioner or another specialist is needed. Many medical schemes also require pre-authorisation for neurosurgical procedures, and that authorisation comes from your scheme rather than from the rooms, although the rooms will usually tell you what codes the scheme will ask for.

Support and escalation routes

Use the rooms for appointments, results and anything concerning the specialist account. Hospital matters, including admission, the ward and the hospital bill, go to Mediclinic George instead.

That split catches a great many patients out. A hospital admission generates at least two separate accounts, one from the hospital for the bed, theatre and consumables, and one from each treating specialist for their own fees. They are billed separately, may be settled differently by a medical scheme, and querying the wrong one wastes a fortnight. Check which account a statement comes from before calling anybody about it.

Complaints divide the same way. Anything about clinical conduct or professional standards goes to the Health Professions Council of South Africa, quoting the registration number above. Anything about the hospital, its facilities or its nursing goes through the Mediclinic patient feedback route. A dispute about what a medical scheme paid is a scheme matter first, and then one for the Council for Medical Schemes.
