You have no idea WTF you’re talking about.
There are multiple competing sets of mutually exclusive codes; different payment schedules and rules per provider and system; AND different sets of all of the above per region, state, and (sometimes) municipality (e.g. New York often gets its own separate rules).
“If you get in an auto accident and the people treating you want to know if you’ve recently had XYZ test, the problem is that every hospital uses a different coding system for that test. WHO was trying to standardize the coding system for those tests”
Seems to me that requires a DD system approach. NOTHING in your original synopsis indicated “different payment schedules”, “different co-pays”, or whatever blather. The original description was that one medic couldn’t tell what tests had been performed at another location.
Additionally, “the internet of things” is a term in the article (electronic devices that update their status on the internet, including coffee makers). THAT does nothing to alleviate determining “which test was run on whom et al”. It does report “heartbeat irregularity from pacemaker 12234221”.
