B35.2 vs J67

B35.2 (Tinea manuum) compared with J67 (Hypersensitivity pneumonitis due to organic dust), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because B35.2 lists J67 under Excludes2, which marks them as distinct conditions.

Official rule

What is different?

The conditions named, billing status and chapter.B35.2 is “Tinea manuum”; J67 is “Hypersensitivity pneumonitis due to organic dust”. J67 is a non-billable header; B35.2 is billable. B35.2 sits in A00-B99 — Certain Infectious and Parasitic Diseases (A00-B99); J67 in J00-J99 — Diseases of the Respiratory System (J00-J99).

Registry fact

Can these codes be reported together?

Yes, when both are documented.B35.2 lists J67 under Excludes2: “hypersensitivity pneumonitis due to organic dust (J67.-)”. 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. J67 carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.B35.2’s tabular entry: “hypersensitivity pneumonitis due to organic dust (J67.-)”. The note covers J67.

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.J67 is a non-billable header, but B35.2 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.

MedCoder-derived

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.B35.2 carries an Excludes2 note covering J67: “hypersensitivity pneumonitis due to organic dust (J67.-)”

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.
