Z44.119 vs Z97

Z44.119 (Encounter for fitting and adjustment of complete artificial leg, unspecified leg) compared with Z97 (Presence of other devices), from the official CMS tabular data.

Summary

These codes should not be reported together because Z44.119’s tabular entry lists Z97 under Excludes1.

Official rule
What is different?

The conditions named and billing status.Z44.119 is “Encounter for fitting and adjustment of complete artificial leg, unspecified leg”; Z97 is “Presence of other devices”. Z97 is a non-billable header; Z44.119 is billable.

Registry fact

Can these codes be reported together?

No.Z44.119’s entry carries an Excludes1 note covering Z97: “presence of prosthetic device (Z97.-)”. Both may be reported only when the documentation shows the two conditions are unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes1 relationship?

Yes.Z44.119’s tabular entry: “presence of prosthetic device (Z97.-)”. The note covers Z97.

Is there an Excludes2 relationship?

Yes.Z97’s tabular entry: “fitting and adjustment of prosthetic and other devices (Z44-Z46)”. The note covers Z44.119.

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.Z97 is a non-billable header, but Z44.119 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

No — do not report together.Z44.119 carries an Excludes1 note covering Z97: “presence of prosthetic device (Z97.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

What to review

Report one of the two. Both may be reported only when the documentation shows the two conditions are unrelated to each other.

Guide: Excludes1 vs Excludes2Check these on a claim

Why it matters

An Excludes1 note means the two conditions cannot occur together, so the pair should not be reported for the same encounter. The sole exception is when the conditions are documented as unrelated to each other.

What we found

Yes, when both are documented.Z97 carries an Excludes2 note covering Z44.119: “fitting and adjustment of prosthetic and other devices (Z44-Z46)”

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.a — Excludes1 · applies to: Excludes1

    A type 1 Excludes note is a pure excludes note. It means “NOT CODED HERE!” An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition. An exception to the Excludes1 definition is the circumstance when the two conditions are unrelated to each other. If it is not clear whether the two conditions involving an Excludes1 note are related or not, query the provider. For example, code F45.8, Other somatoform disorders, has an Excludes1 note for "sleep related teeth grinding (G47.63)," because "teeth grinding" is an inclusion term under F45.8. Only one of these two codes should be assigned for teeth grinding. However psychogenic dysmenorrhea is also an inclusion term under F45.8, and a patient could have both this condition and sleep related teeth grinding. In this case, the two conditions are clearly unrelated to each other, and so it would be appropriate to report F45.8 and G47.63 together.

    ICD-10-CM Official Guidelines FY2026

  • 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.
