Before you code Z02

  1. Z02 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).

    ReviewZ02.0, Z02.1, Z02.2, Z02.3, Z02.4, Z02.5, Z02.6, Z02.7, Z02.8, Z02.9

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

  2. Confirm the reason for the encounter this Z code records: an examination or encounter with no complaint or diagnosis. 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).

Choose the right path

  1. Does the documentation support one of the more specific codes beneath Z02?
    Yes → Select that code and continue the checks below on its own page.
    No → Z02 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewZ02.0, Z02.1, Z02.2, Z02.3, Z02.4, Z02.5, Z02.6, Z02.7, Z02.8, Z02.9

Consider Z02. Then 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 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).

Referenced by 2 Excludes1 notes: Z00 — Encounter for general examination without complaint, suspected or reported diagnosis, Z01 — Encounter for other special examination without complaint, suspected or reported diagnosis.

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

Referenced by 1 Excludes2 note: Z71.84 — Encounter for health counseling related to travel.

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
