Z87.68 vs Z87.7

Z87.68 (Personal history of other (corrected) conditions arising in the perinatal period) compared with Z87.7 (Personal history of (corrected) congenital malformations), from the official CMS tabular data.

Summary

These codes should not be reported together because Z87.68’s tabular entry lists Z87.7 under Excludes1.

Official rule
What is different?

Title wording and billing status.The titles share “Personal history of”; Z87.68 says “other (corrected) conditions arising in the perinatal period” where Z87.7 says “(corrected) congenital malformations”. Z87.7 is a non-billable header; Z87.68 is billable.

Registry fact

Can these codes be reported together?

No.Z87.68’s entry carries an Excludes1 note covering Z87.7: “personal history of (corrected) congenital malformations (Z87.7-)”. 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.Z87.68’s tabular entry: “personal history of (corrected) congenital malformations (Z87.7-)”. The note covers Z87.7.

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes2 relationship?

None.Neither entry carries an Excludes2 note that names the other code. Z87.7 carries 7 Excludes2 notes covering other codes; the side-by-side table quotes them.

Official rule

Is one more specific?

No.Neither is a subdivision of the other, and neither title is the unspecified form; they describe different conditions within category Z87.

Registry fact

Is one a parent or header code?

One is a header.Z87.7 is a non-billable header, but Z87.68 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.Z87.68 carries an Excludes1 note covering Z87.7: “personal history of (corrected) congenital malformations (Z87.7-)”

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.

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.
