S02.102G vs S02.83

S02.102G (Fracture of base of skull, left side, subsequent encounter for fracture with delayed healing) compared with S02.83 (Fracture of medial orbital wall), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because S02.102G lists S02.83 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

Title wording and billing status.The titles share “Fracture of”; S02.102G says “base of skull, left side, subsequent encounter for fracture with delayed healing” where S02.83 says “medial orbital wall”. S02.83 is a non-billable header; S02.102G is billable.

Registry fact

Can these codes be reported together?

Yes, when both are documented.S02.102G lists S02.83 under Excludes2: “medial orbital wall (S02.83-)”. 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.S02.102G’s tabular entry: “medial orbital wall (S02.83-)”. The note covers S02.83.

Official ruleGuide: Excludes1 vs Excludes2

Is one more specific?

No.Neither is a subdivision of the other, and neither title is the unspecified form; they describe different conditions within category S02.

Registry fact

Is one a parent or header code?

One is a header.S02.83 is a non-billable header, but S02.102G 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.S02.102G carries an Excludes2 note covering S02.83: “medial orbital wall (S02.83-)”

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.

Source / rule

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.
