Summary

These codes can be reported together when both conditions are documented, because Z87.898 lists Z91.5 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

Title wording and billing status.The titles share “Personal history of”; Z87.898 says “other specified conditions” where Z91.5 says “self-harm”. Z91.5 is a non-billable header; Z87.898 is billable.

Yes, when both are documented.Z87.898 lists Z91.5 under Excludes2: “personal history of self harm (Z91.5-)”. Excludes2 marks distinct conditions that may both be reported when both are documented.

Is one a parent or header code?

One is a header.Z91.5 is a non-billable header, but Z87.898 is not one of its subdivisions.

Registry fact

Nothing found in 3 other checks; 1 check does not apply
Is there an Excludes1 relationship?

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

Official rule

Is one more specific?

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

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.Z87.898 carries an Excludes2 note covering Z91.5: “personal history of self harm (Z91.5-)”

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.

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.

Notes are the code’s own tabular entry, quoted as published. A note that names the other code is the one the verdict above rests on. In a row that differs, each code’s own notes are listed under it, and the notes every code shares are listed once beneath them.
