I'm not sure that this is 400 words but this is what I came up with.
Answer:
Patients medical history and records are meant to be confidential. The coders discussing on the diagnosis listed on a patient’s file and commenting on the patient’s past social history in relation to the diagnosis listed in the medical record is totally unacceptable.
I would make sure I warn them to desist from going against the ethics of the profession or make up evidences and report them to the relevant authorities.
