MDA is an Australian television series that aired between 2002 and 2005 on the Australian Broadcasting Corporation . It concerned the day-to-day operation of legal firm MDA, which specialised in medical defence. The title refers to the firm Medical Defence Australia, a team of lawyers and doctors who defend doctors charged with malpractice, ranging from Botox injections gone wrong to spinal cord injuries. The firm operates by collecting annual subscriptions from doctors, rather than on a case-by-case fee basis.
