Z00.71 vs Z13

Z00.71 (Encounter for examination for period of delayed growth in childhood with abnormal findings) compared with Z13 (Encounter for screening for other diseases and disorders), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because Z00.71 lists Z13 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

Title wording and billing status.The titles share “Encounter for”; Z00.71 says “examination for period of delayed growth in childhood with abnormal findings” where Z13 says “screening for other diseases and disorders”. Z13 is a non-billable header; Z00.71 is billable.

Registry fact

Can these codes be reported together?

Yes, when both are documented.Z00.71 lists Z13 under Excludes2: “special screening examinations (Z11-Z13)”. 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. Z00.71 carries 1 Excludes1 note and Z13 carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.Z00.71’s tabular entry: “special screening examinations (Z11-Z13)”. The note covers Z13.

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).

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.
