Documentation tips
- Make sure the note supports every element of the title, “Contact with and (suspected) exposure to other hazardous aromatic compounds”: each detail in it should be traceable to the history, examination or assessment.
- Code to the highest specificity the documentation supports. If a detail is missing from the note, add it to the note rather than choosing a less specific code by default.
- Check the Tabular List and official guidelines for instructional notes (“code first”, “use additional code”, Excludes1/Excludes2) that apply to Z77.
