What diagnoses codes are you seeing work (I know they vary among insurances) for covering lipid panels, TSH panels, and A1C panels? Screening codes are variable it seems. I feel like this is a common question, but the longer we do this, the more questions we have. For example, if a patient is presenting with chronic fatigue, and provider suspects or at least want to rule out a thyroid issue, what code would you use that usually gets covered? Thanks!
