SUBJECT: Posterior reversible encephalopathy syndrome
Q:
How do you code posterior reversible encephalopathy syndrome?
A:
Posterior reversible encephalopathy syndrome (PRES) (also known as reversible posterior leukoencephalopathy syndrome) presents with symptoms such as headaches, altered mental state, seizures and visual disturbances. The exact cause is unclear, but most cases of PRES occur with or are due to hypertension (including eclampsia), immunosuppression (including secondary to immunosuppressive treatment), autoimmune disease, antineoplastic agents and renal failure. Radiological (MRI) findings of oedema involving the posterior occipital and parietal lobes of the brain are indicative of PRES and are essential for diagnosis, as PRES is difficult to diagnose clinically. Early diagnosis and treatment is vital to prevent sequelae. Complete reversal of clinical symptoms within weeks is possible if treatment is commenced immediately; which includes withdrawing causative agents and treating severe hypertension and seizures.
The correct code to assign for posterior reversible encephalopathy syndrome is:
