Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for K74.0 in the official ICD-10-CM tabular list, quoted as published.

Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025

Notes without a marker are published on K74.0 itself; “inherited from” names the category or block whose note applies here.

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Source: inherited from K70-K77

Code First

Underlying conditions that must be sequenced before this code.

  • underlying liver disease, such as:
  • nonalcoholic steatohepatitis (NASH) (K75.81)

Code Also

Additional codes that may be required to fully describe the encounter.

  • Code also, if applicable, viral hepatitis (acute) (chronic) (B15-B19)

Coder workflow for K74.0

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

Before you code K74.0

  1. K74.0 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).

    ReviewK74.00, K74.01, K74.02, K74.0A

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

  2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with K74.0. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).

    See the official tabular notes

Choose the right path

  1. Does the documentation support one of the more specific codes beneath K74.0?
    Yes → Select that code and continue the checks below on its own page.
    No → K74.0 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewK74.00, K74.01, K74.02, K74.0A

  2. Does the documentation support a condition named in K74.0’s Excludes1 note?
    Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
    No → Continue.

    ReviewK70.3, K70.2, K76.1, K71.7, P78.81, E83.110

  3. Is the underlying (etiologic) condition the Code First note names documented?
    Yes → Sequence the underlying condition first, then K74.0.
    No → Continue; do not add an underlying condition the record does not document.

    ReviewK75.81

Consider K74.0. 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).

Official instructions as workflow

  • Excludes1 — check before selecting K74.0(7 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with K74.0: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareK70.3, K70.2, K76.1, K71.7, P78.81, E83.110

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

  • Excludes2 — not part of K74.0(4 notes)

    Coding workflow: The conditions named in this note are not included in K74.0. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareE83.11, G93.7, E83.01

    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 K74.0. Do not add an underlying condition the record does not document.

    ReviewK75.81

    See the official tabular notes · Guidelines I.A.13

  • Code Also — related condition(1 note)

    Coding workflow: Review the related condition when both are documented and the instruction applies. A Code Also note does not fix sequencing; the order follows the circumstances of the encounter.

    See the official tabular notes · Guidelines I.A.17

Coding decision scenarios

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

Documentation: Both the condition K74.0 describes and a condition named in its Excludes1 note are documented for the same encounter.

Coding question: Can both codes be reported?

Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.

Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).

ReviewK70.3, K70.2, K76.1, K71.7, P78.81, E83.110

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).

ReviewK75.81

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

Hepatic fibrosis is a non-billable ICD-10-CM category code (K74.0). A more specific billable subcode must be selected for claims submission.

MedCoder summary Summary composed by MedCoder from this code's official ICD-10-CM record. The tabular instructional notes themselves appear verbatim below.

Decision Points

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

  1. Sequencing: 2 Code First instructions — the underlying condition is sequenced before this code when present. See the Code First notes
  2. 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
  3. 7 Excludes1 entries — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
  4. 4 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.
