Summary

Z85.828 is the personal-history or screening code for the active disease D04.39 names, so the two are not interchangeable.

MedCoder-derived

What is different?

The conditions named and chapter.D04.39 is “Carcinoma in situ of skin of other parts of face”; Z85.828 is “Personal history of other malignant neoplasm of skin”. D04.39 sits in C00-D49 — Neoplasms (C00-D49); Z85.828 in Z00-Z99 — Factors Influencing Health Status and Contact with Health Services (Z00-Z99).

Registry fact

Can these codes be reported together?

Not for the same condition.Z85.828 is the personal-history or screening code for the active disease D04.39 names. Site match derived from the code’s own title against the CMS/CDC Table of Neoplasms. A personal-history code describes a condition that no longer exists and is no longer being treated, so it is not interchangeable with the active-disease code.

Is there an Excludes1 relationship?

None.Neither entry carries an Excludes1 note that names the other code. D04.39 carries 2 Excludes1 notes covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

None.Neither entry carries an Excludes2 note that names the other code. Z85.828 carries 2 Excludes2 notes covering other codes; the side-by-side table quotes them.

Official rule

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?

No.Both are billable codes, and neither contains the other.

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?

Yes.History or screening versus active disease. Z85.828 is the personal-history or screening code for the active disease D04.39 names.

What we found

History or screening versus active disease.Z85.828 is the personal-history or screening code for the active disease D04.39 names.

Site match derived from the code’s own title against the CMS/CDC Table of Neoplasms. A personal-history code describes a condition that no longer exists and is no longer being treated, so it is not interchangeable with the active-disease code.

What to review

Report the history code when the condition no longer exists and is no longer treated; report the active-disease code while it is.

Why it matters

A personal-history code describes a condition that no longer exists and is no longer being treated, so it is not interchangeable with the active-disease code for the same site.
