S82 (Fracture of lower leg, including ankle) compared with S96.09 (Other injury of muscle and tendon of long flexor muscle of toe at ankle and foot level), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because S82 lists S96.09 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

The conditions named.S82 is “Fracture of lower leg, including ankle”; S96.09 is “Other injury of muscle and tendon of long flexor muscle of toe at ankle and foot level”.

Registry fact

Can these codes be reported together?

Yes, when both are documented.S82 lists S96.09 under Excludes2: “injuries of ankle and foot, except fracture of ankle and malleolus (S90-S99)”. 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. S82 carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.S82’s tabular entry: “injuries of ankle and foot, except fracture of ankle and malleolus (S90-S99)”. The note covers S96.09.

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?

Both are headers.Both are non-billable headers, 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.

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.
