I am hoping someone can help me with this. If a patient is having a MSLT test to check for narcolepsy but the results come back negative, what diagnosis code do you use? I've found information in the LCD that states 'diagnostic testing is covered when the patient has the symptoms of narcolepsy and the diagnosis is usually confirmed with the test.' But what if the diagnosis is not confirmed?? Thank you for any help.
