Coder workflow for I74

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

Before you code I74

  1. I74 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).

    ReviewI74.0, I74.1, I74.2, I74.3, I74.4, I74.5, I74.8, I74.9

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

Choose the right path

  1. Does the documentation support one of the more specific codes beneath I74?
    Yes → Select that code and continue the checks below on its own page.
    No → I74 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewI74.0, I74.1, I74.2, I74.3, I74.4, I74.5, I74.8, I74.9

  2. Is the underlying (etiologic) condition the Code First note names documented?
    Yes → Sequence the underlying condition first, then I74.
    No → Continue; do not add an underlying condition the record does not document.

    ReviewO08.2, O88

Consider I74. 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 underlying (etiologic) condition
Named in the Code First note; sequenced before this code when documented (Guidelines I.A.13).

Official instructions as workflow

  • Excludes2 — not part of I74(13 notes)

    Coding workflow: The conditions named in this note are not included in I74. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

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

  • Code First — sequencing check(2 notes)

    Coding workflow: Check whether the underlying or etiologic condition the note names is documented. When it is, sequence it before I74. 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).

ReviewO08.2, O88

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.

Code Overview
