My thoughts would be the work order to take the sample would be a preventative maintenance. Any recommendations for maintenance based on the results would then be scheduled as a corrective maintenance due to the fact that you will be correcting an abnormality. The decision is a hard one because if you correct the oil then it is my understanding that you are also preventing it from deteriorating.

Tomato or Tomato?
So long as you capture it the same way al the time it probably shouldn't matter.

Good luck

I would say yes. Rarely have I see an OEM tell me what preservative oil they used and if that is the same as the recommended oil. I wouldn't want to use an oil that has sat in a machine during storage without knowing the details of the lubricant and it's condition. Too much opportunity for water or particulate contamination. Drain/flush and start fresh. Don't forget to baseline the new oil with your lab.

To the original question as to what the follow up work should be coded - I certainly believe that the initial oil sampling work order would be a PM or PdM (preventive or predictive) and the follow up for an oil change would be a CM (corrective) as the condition no longer warrants further use.  We have created in our CMMS work order system a code called a CPM (corrective from a PM) which helps us understand how effective our PM work orders are in finding abnormal conditions.
