Hi! I want to ask what diagnosis code can we use as primary if the patient comes for psychotherapy for anxiety or depression due to a physical chronic condition (cancer, parkinson, alzheimer, dementia, etc) (for ex. F06.4 (secondary code) -Anxiety disorder due to known physiological condition). We need to code first the physiological condition. Knowing the guidelines of the advantage coverage or medicare, a psychologist can't diagnose a patient with a chronic condition, just because the patient says so, there is no evidence of the diagnosis or treatment on the medical record. I hope you can help me with this thread.
