I87.2 vs L20-L30

I87.2 (Venous insufficiency (chronic) (peripheral)) compared with L20-L30 (Dermatitis and eczema (L20-L30)), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because L20-L30 lists I87.2 under Excludes2, which marks them as distinct conditions.

Official rule

What is different?

The conditions named, billing status and chapter.I87.2 is “Venous insufficiency (chronic) (peripheral)”; L20-L30 is “Dermatitis and eczema (L20-L30)”. L20-L30 is a non-billable header; I87.2 is billable. I87.2 sits in I00-I99 — Diseases of the Circulatory System (I00-I99); L20-L30 in L00-L99 — Diseases of the Skin and Subcutaneous Tissue (L00-L99).

Registry fact

Can these codes be reported together?

Yes, when both are documented.L20-L30 lists I87.2 under Excludes2: “stasis dermatitis (I87.2)”. 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. I87.2 carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.L20-L30’s tabular entry: “stasis dermatitis (I87.2)”. The note covers I87.2.

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.L20-L30 is a non-billable header, but I87.2 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.

Official rule: a tabular instructional note or a section of the ICD-10-CM Official Guidelines, quoted as published. Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set).

What we found

Yes, when both are documented.L20-L30 carries an Excludes2 note covering I87.2: “stasis dermatitis (I87.2)”

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.
