When is it appropriate to use the z20.822 vs the z11.52? In the past we used the z20.822 Known or suspected contact with or exposure to. If person is seen in ED or Urgent Care now, would it be more appropriate to use the z11.52 screening for Covid if there is no documentation that the person had actual contact with or possible exposure? If there is suspected exposure (general or know) and it is documented then I believe z20.822 would be appropriate. Does anyone have an formal guidelines they could share or any information or direction as to where I can find some.
