Summary

These codes can be reported together when both conditions are documented, because N13.72 lists Q62.11 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

The conditions named, billing status and chapter.N13.72 is “Vesicoureteral-reflux with reflux nephropathy without hydroureter”; Q62.11 is “Congenital occlusion of ureteropelvic junction”. N13.72 is a non-billable header; Q62.11 is billable. N13.72 sits in N00-N99 — Diseases of the Genitourinary System (N00-N99); Q62.11 in Q00-QA1 — Congenital Malformations, Deformations and Chromosomal Abnormalities (Q00-QA1).

Registry fact

Can these codes be reported together?

Yes, when both are documented.N13.72 lists Q62.11 under Excludes2: “hydronephrosis with ureteropelvic junction obstruction (Q62.11)”. 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. N13.72 carries 2 Excludes1 notes covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.N13.72’s tabular entry: “hydronephrosis with ureteropelvic junction obstruction (Q62.11)”. The note covers Q62.11.

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.N13.72 is a non-billable header, but Q62.11 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.

MedCoder-derived

Official rule: a tabular instructional note or a section of the ICD-10-CM Official Guidelines, quoted as published. Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set). MedCoder-derived: a reading MedCoder computes from those facts; it is not itself a rule. How to read the labels

What we found

Yes, when both are documented.N13.72 carries an Excludes2 note covering Q62.11: “hydronephrosis with ureteropelvic junction obstruction (Q62.11)”

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.

CMS ICD-10-CM tabular instructional notes

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.
