Coder workflow for Z31

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

Before you code Z31

  1. Z31 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).

    ReviewZ31.0, Z31.4, Z31.5, Z31.6, Z31.7, Z31.8, Z31.9

    See the relationships section · Guide: How to choose an ICD-10-CM code →

  2. Confirm the reason for the encounter this Z code records: the circumstance it records. 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, I.C.21.c.15).

    Guide: Z codes as principal or first-listed diagnosis →

Choose the right path

  1. Does the documentation support one of the more specific codes beneath Z31?
    Yes → Select that code and continue the checks below on its own page.
    No → Z31 cannot be reported as written. Where the codes beneath it include an unspecified code, that code applies when the record goes no further; otherwise query for the missing detail.

    ReviewZ31.0, Z31.4, Z31.5, Z31.6, Z31.7, Z31.8, Z31.9

Report the code beneath Z31 that the documentation supports, not Z31 itself. Then confirm that code is valid for the date of service on its own page.

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 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).

Official instructions as workflow

  • Excludes2 — not part of Z31(3 notes)

    Coding workflow: The conditions named in this note are not included in Z31. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareN98, N97, N46

    See the official tabular notes · Guidelines I.A.12.b

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.
