A code page names the day it stops
A stop day tells a reader whether the code is still in use.
A code page carries four lines: the name, the coverage, the exclusion, and the stop day. The stop day is not a forecast horizon and it is not a billing cycle. After that day, the page leaves use. A direct line and an entry book each keep their own date. They do not borrow the code page’s stop day. This reading is not a software specification, a medical bill, or legal advice.
- All four lines are present
- Past the stop day, the page leaves use
- Do not call the stop day a billing cycle
- Other pages keep their own dates
