Summary

These codes can be reported together when both conditions are documented, because F10.229 lists T51.0X3D under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

The conditions named and chapter.F10.229 is “Alcohol dependence with intoxication, unspecified”; T51.0X3D is “Toxic effect of ethanol, assault, subsequent encounter”. F10.229 sits in F01-F99 — Mental, Behavioral and Neurodevelopmental Disorders (F01-F99); T51.0X3D in S00-T88 — Injury, Poisoning and Certain Other Consequences of External Causes (S00-T88).

Registry fact

Can these codes be reported together?

Yes, when both are documented.F10.229 lists T51.0X3D under Excludes2: “toxic effect of alcohol (T51.0-)”. 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. F10.229 carries 2 Excludes1 notes and T51.0X3D carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.F10.229’s tabular entry: “toxic effect of alcohol (T51.0-)”. The note covers T51.0X3D.

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?

No.Both are billable codes, and neither contains the other.

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.

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

What we found

Yes, when both are documented.F10.229 carries an Excludes2 note covering T51.0X3D: “toxic effect of alcohol (T51.0-)”

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.
