Questions About Excludes1 Notes

What does an Excludes1 note mean?

An Excludes1 note means “NOT CODED HERE!”: the excluded code should never be used at the same time as the code above the note. It is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition (Section I.A.12.a). The FY 2027 Tabular List has 5,411 of them; 5,284 name other codes, with 5,710 references to 3,528 distinct codes, categories and ranges.

Is there any exception to an Excludes1 note?

Yes: when the two conditions are unrelated to each other. The Guidelines’ example is F45.8, whose Excludes1 note names sleep related teeth grinding (G47.63). A patient with psychogenic dysmenorrhea (an inclusion term of F45.8) and teeth grinding may have both codes reported. If it is not clear whether the conditions are related, query the provider.
