M80.00XP vs Z87.310

M80.00XP (Age-related osteoporosis with current pathological fracture, unspecified site, subsequent encounter for fracture with malunion) compared with Z87.310 (Personal history of (healed) osteoporosis fracture), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because M80.00XP lists Z87.310 under Excludes2, which marks them as distinct conditions.

Official rule

What is different?

The conditions named and chapter.M80.00XP is “Age-related osteoporosis with current pathological fracture, unspecified site, subsequent encounter for fracture with malunion”; Z87.310 is “Personal history of (healed) osteoporosis fracture”. M80.00XP sits in M00-M99 — Diseases of the Musculoskeletal System and Connective Tissue (M00-M99); Z87.310 in Z00-Z99 — Factors Influencing Health Status and Contact with Health Services (Z00-Z99).

Registry fact

Can these codes be reported together?

Yes, when both are documented.M80.00XP lists Z87.310 under Excludes2: “personal history of (healed) osteoporosis fracture (Z87.310)”. 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. M80.00XP carries 3 Excludes1 notes covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

Yes.M80.00XP’s tabular entry: “personal history of (healed) osteoporosis fracture (Z87.310)”. The note covers Z87.310.

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?

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?

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

Yes, when both are documented.M80.00XP carries an Excludes2 note covering Z87.310: “personal history of (healed) osteoporosis fracture (Z87.310)”

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.

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.

Definition	Age-related osteoporosis with current pathological fracture, unspecified site, subsequent encounter for fracture with malunion is a billable ICD-10-CM diagnosis code (M80.00XP).	Personal history of (healed) osteoporosis fracture is a billable ICD-10-CM diagnosis code (Z87.310).

Notes are the code’s own tabular entry, quoted as published. A note that names the other code is the one the verdict above rests on.
