Z13.7 vs Z31.440

Z13.7 (Encounter for screening for genetic and chromosomal anomalies) compared with Z31.440 (Encounter of male for testing for genetic disease carrier status for procreative management), from the official CMS tabular data.

Summary

These codes should not be reported together because Z13.7’s tabular entry lists Z31.440 under Excludes1.

Official rule
What is different?

The conditions named and billing status.Z13.7 is “Encounter for screening for genetic and chromosomal anomalies”; Z31.440 is “Encounter of male for testing for genetic disease carrier status for procreative management”. Z13.7 is a non-billable header; Z31.440 is billable.

Registry fact

Can these codes be reported together?

No.Z13.7’s entry carries an Excludes1 note covering Z31.440: “genetic testing for procreative management (Z31.4-)”. 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.Z13.7’s tabular entry: “genetic testing for procreative management (Z31.4-)”. The note covers Z31.440.

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes2 relationship?

Yes.Z13.7’s tabular entry: “examinations related to pregnancy and reproduction (Z30-Z36, Z39.-)”. The note covers Z31.440.

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.Z13.7 is a non-billable header, but Z31.440 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.

Can these codes be reported together?

What we found

No — do not report together.Z13.7 carries an Excludes1 note covering Z31.440: “genetic testing for procreative management (Z31.4-)”

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 are not ordinarily reported together for the same encounter, because the classification treats them as mutually exclusive forms of the same condition. The documented exception is when the two conditions are unrelated to each other.

What we found

Yes, when both are documented.Z13.7 carries an Excludes2 note covering Z31.440: “examinations related to pregnancy and reproduction (Z30-Z36, Z39.-)”

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.

Guide: Excludes1 vs Excludes2Check these on a claim

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.
