Questions About Code Also Notes

What does a Code Also note mean?

A Code Also note instructs that two codes may be required to fully describe a condition, but it does not give sequencing direction (Section I.A.17). The FY 2027 Tabular List has 689 of them; 495 name other codes, with 538 references to 349 distinct codes, categories and ranges.

Which code goes first with a Code Also note?

The note does not decide it. Sequencing depends on the circumstances of the encounter: normally the condition that is the main reason for the visit goes first.
