Is there an Excludes1 relationship?

None.Neither entry carries an Excludes1 note that names the other code. S11.22XS carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.S11.22XS’s tabular entry: “effects of foreign body in larynx (T17.3)”. The note covers T17.3.

Official ruleGuide: Excludes1 vs Excludes2

Is one more specific?

Not comparable.The codes sit in different categories; specificity is only comparable within one category.

Is one a parent or header code?

One is a header.T17.3 is a non-billable header, but S11.22XS is not one of its subdivisions.

Registry fact

Are there sequencing instructions?

None.Neither entry carries a Code First or Use Additional Code note that names the other.

Are there other coding relationships?

None found.No laterality, encounter-phase, Table of Neoplasms, Table of Drugs and Chemicals, or history-versus-active-disease relationship links these codes.

Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set).

What we found

Yes, when both are documented.S11.22XS carries an Excludes2 note covering T17.3: “effects of foreign body in larynx (T17.3)”

Why it matters

An Excludes2 note means the excluded condition is not part of the code above it, but a patient can have both. Report both when both are documented.

Official guidance behind these answers

  • Section I.A.12.b — Excludes2 · applies to: Excludes2

    A type 2 Excludes note represents “Not included here.” An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
