M70.10 vs M76

M70.10 (Bursitis, unspecified hand) compared with M76 (Enthesopathies, lower limb, excluding foot), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because M70.10 lists M76 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

The conditions named and billing status.M70.10 is “Bursitis, unspecified hand”; M76 is “Enthesopathies, lower limb, excluding foot”. M76 is a non-billable header; M70.10 is billable.

Registry fact

Can these codes be reported together?

Yes, when both are documented.M70.10 lists M76 under Excludes2: “enthesopathies (M76-M77)”. 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. M70.10 carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.M70.10’s tabular entry: “enthesopathies (M76-M77)”. The note covers M76.

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.M76 is a non-billable header, but M70.10 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.

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

What we found

Yes, when both are documented.M70.10 carries an Excludes2 note covering M76: “enthesopathies (M76-M77)”

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.
