Coding at a Glance

Tabular directives: 7 Excludes2 · 1 code-first instruction · 1 code-also instruction

Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43, Appendix B.

MS-DRG 951 — OTHER FACTORS INFLUENCING HEALTH STATUS (MDC 23)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for Z87.718 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on Z87.718 itself; “inherited from” names the category or block whose note applies here.

Coder workflow for Z87.718

MedCoder structured workflow — derived from this code’s own official record

Before you code Z87.718

“Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on Z87.718; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).
ReviewZ87.710
See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →
Confirm the reason for the encounter this Z code records: a personal or family history — a condition no longer present or present in a relative — never a current condition. Check whether the code may be reported as first-listed or principal — some Z codes are limited to one position — and do not report a history or status code for a condition documented as current. Z code categories and their reporting positions (Guidelines I.C.21.c.4, I.C.21.c.15).
Guide: History codes (Z codes) →

Choose the right path

Is the underlying (etiologic) condition the Code First note names documented?
Yes → Sequence the underlying condition first, then Z87.718.
No → Continue; do not add an underlying condition the record does not document.
ReviewZ09

Consider Z87.718. Then review the Code Also note, and confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement: Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
The underlying (etiologic) condition: Named in the Code First note; sequenced before this code when documented (Guidelines I.A.13).
The reason for the encounter: Whether the code records the encounter’s purpose, a status, or a history — and whether it may be first-listed (Guidelines I.C.21.c).
Any detail beyond this code’s title: What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

Official instructions as workflow

Excludes2 — not part of Z87.718(7 notes)
Coding workflow: The conditions named in this note are not included in Z87.718. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Code First — sequencing check(1 note)
Coding workflow: Check whether the underlying or etiologic condition the note names is documented. When it is, sequence it before Z87.718. Do not add an underlying condition the record does not document.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: The underlying condition the Code First note names is documented alongside this condition.

Coding question: How are the two sequenced?

Path: Review the Code First note.

Reason: The underlying condition is sequenced first and the manifestation follows (Guidelines I.A.13).

ReviewZ09

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Decision Points

The directives on this code's own record, as a pre-claim checklist.

Sequencing: 1 Code First instruction — the underlying condition is sequenced before this code when present. See the Code First notes
1 Code Also note — a second code may apply; the guidelines leave its sequencing to the circumstances of the encounter. See the Code Also notes
7 Excludes2 entries — those conditions are not part of this code and may be reported additionally when documented. See the Excludes2 notes

Checklist rows are derived from this code's own official directives; the wording of each check is MedCoder editorial. The official notes themselves are in the sections each row links to.

Verify Before Coding

Principal-diagnosis restriction. The Medicare Code Editor lists this code as unacceptable as a principal diagnosis: it describes a circumstance influencing health status rather than a current illness or injury being treated. It is valid as a secondary diagnosis.

From the code registry, the Medicare Code Editor, and the MS-DRG Definitions Manual. Check it against a full claim in Claim Check.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name Z87.718 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 1 Excludes1 note: Z87.6 — Personal history of certain (corrected) conditions arising in the perinatal period (via Z87.7.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 1 Use Additional Code instruction: Z09 — Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm (via Z87.-).

These codes instruct coders to additionally report this code when it applies.
