Headcase,
As a part of our Meaningful Use Certification we updated our problem vocabulary to the SNOMED problem vocabulary instead of of just the ICD-9 problem vocabulary. You'll notice there are some ICD-9 codes that map to two or three different SNOMED descriptions, so the ICD-9 code will show up more than once.
You've already notice that there are no longer yellow ICD-9 codes in the Problem search list (which means that all the ICD-9s that are in the problem list are billable!). However, in the Billing screens, the yellow ICD-9 codes are still available for historic reasons or if you happen to need them.
There are still yellow codes in the problem search from the Most Recent Encounter and you'll see those have a '000' code -- these are SNOMED problem descriptions that are clinically valid, but don't have an associated ICD-9 code and therefore aren't billable.
I hope that helps! Again, please let me know if you need any further clarification.
