Even though systems are electronic and the 51 is pretty much obsolete; I would still list them correctly in RVU order. When looking at the case or service if there are multiple lines it makes more sense this way. You can also more easily see if something is missing and/or other problems if they are in RVU order. There may also be an internal reason to do this with data analytics and other spreadsheets or info that may be pulled internally from your EHR/EMR. If it was up to me, I would not recommend just haphazardly adding codes out of order. I feel like the standard should be kept and followed. I also don't necessarily trust multiple procedure reductions to be applied correctly 100% of the time. Also, when training newer coders and for people who are learning, it is much easier to teach it in RVU order.
I also think of post-claim adjudication and what the EOB or ERA looks like, look at it from a payment posting perspective and from the eye of a customer service rep or someone else helping a patient with a bill, etc. The dollars will usually start higher and go down from there.
Especially in ortho, think of it if you had a big spine case and it was listed like this (not saying these are correct or would be billed together, just as an example):
20936
63052
22842
22853
22633
22830
22614
This would just be off kilter, could lead to entry errors, diagnoses linkage errors, and code first rules may or may not apply. It just does not make sense to me to do this. Maybe if it is a different specialty, but not orthopedics.
Or, even office procedures with E/M? Can you imagine looking at a billing screen like this? Totally weird.
