He said the department would only take legal action against individual debtors, not the embassies. Gauteng attracts millions of migrants who use public health and education facilities, putting a strain on public coffers.
According to the department, the most debts were accumulated at Charlotte Maxeke Johannesburg Academic Hospital in Parktown, followed by Dr George Mukhari in GaRankuwa and Steve Biko Academic Hospital in Pretoria.
Finance MEC Barbara Creecy, who allocated an additional R1.7-billion to the health department last week, said it was crucial that the department collected money from those who utilise public health facilities and can afford to pay.
The health department's budget for the year stands at R40.2-billion.
The department was also owed millions of rands by other provinces who refer patients - for treatment and surgeries - to Gauteng.
Matuka said the three provinces that owed a total of R93-million were North West, Limpopo and Mpumalanga.
He said North West and Mpumalanga have already begun to service their debts, having paid R1.7-million and R421000 respectively.
DA spokesman Jack Bloom said he believed that the department's move against foreigners to recoup money was "a futile exercise".
