Summary

These codes can be reported together when both conditions are documented, because S27.409S lists S19 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

The conditions named and billing status.S19 is “Other specified and unspecified injuries of neck”; S27.409S is “Unspecified injury of bronchus, unspecified, sequela”. S19 is a non-billable header; S27.409S is billable.

Registry fact

Can these codes be reported together?

Yes, when both are documented.S27.409S lists S19 under Excludes2: “injury of cervical esophagus (S10-S19)”. Excludes2 marks distinct conditions that may both be reported when both are documented.

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes1 relationship?

None.Neither entry carries an Excludes1 note that names the other code.

Official rule

Is there an Excludes2 relationship?

Yes.S27.409S’s tabular entry: “injury of cervical esophagus (S10-S19)”. The note covers S19.

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.S19 is a non-billable header, but S27.409S 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.

Official rule

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.

What we found

Yes, when both are documented.S27.409S carries an Excludes2 note covering S19: “injury of cervical esophagus (S10-S19)”

Excludes2 marks distinct conditions — both may be reported when both are documented.

What to review

Report both only when the documentation supports both conditions; otherwise report the one documented.

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.

CMS ICD-10-CM tabular instructional notes

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.
