Wiki How to code Medicare Preop evaluation

[dayescobarmor]

What code should I use for a Preop evaluation for a patient that is going for cataract surgery and has Medicare for insurance? I use as first diagnosis Z01.818 and was denied. Do I have to use the Z code as a second diagnosis and code the reason of the surgery first?

Z01 codes are all first listed only allowed. What was the denial reason?
