Coder workflow for C92.3

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

Before you code C92.3

  1. C92.3 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).

    ReviewC92.30, C92.31, C92.32

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

  2. Confirm the documented site and behavior (this code’s block classifies malignant neoplasms), whether the site is primary or secondary, and whether the malignancy is current or a personal history: a previously excised malignancy with no further treatment and no evidence of disease is history, not current disease. Verify the site against the Table of Neoplasms. Neoplasm chapter guidelines (Guidelines I.C.2.a, I.C.2.d, I.C.2.m).

    See the Table of Neoplasms entries · Guide: Active cancer vs history of cancer →

  3. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with C92.3. 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 C92.3?
    Yes → Select that code and continue the checks below on its own page.
    No → C92.3 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewC92.30, C92.31, C92.32

  2. Does the documentation support a condition named in C92.3’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.

    ReviewZ85.6

Consider C92.3. 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).
Anatomical site
At the most specific level the record states; a site the classification separates cannot be assumed from a procedure or a measurement.
Acuity
Acute or chronic as documented; when both are documented and separate codes exist, both are reported with the acute code first (Guidelines I.B.8).
The associated condition or complication
Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).
Behavior and current-versus-history status
Malignant, in situ, benign or uncertain; primary or secondary; current disease or personal history (Guidelines I.C.2.m).

Official instructions as workflow

  • Excludes1 — check before selecting C92.3(1 note)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with C92.3: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareZ85.6

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

  • Excludes2 — not part of C92.3(4 notes)

    Coding workflow: The conditions named in this note are not included in C92.3. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareC46.3, C77, C79.52, C78.89

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

  • 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.

Coding decision scenarios

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

Documentation: Both the condition C92.3 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).

Code Overview

Myeloid sarcoma is a non-billable ICD-10-CM category code (C92.3). A more specific billable subcode must be selected for claims submission.

Decision Points

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

  1. 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
  2. 1 Excludes1 entry — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
  3. 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.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name C92.3 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 5 Excludes1 notes across 4 chapters: C76 — Malignant neoplasm of other and ill-defined sites (via C92.-), D72.8 — Other specified disorders of white blood cells (via C92.-), D72.825 — Bandemia (via C92.-), T66 — Radiation sickness, unspecified (via C92.-), Z85.6 — Personal history of leukemia (via C92.-).

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

Referenced by 4 Code First instructions across 4 chapters: M36.1 — Arthropathy in neoplastic disease (via C92.-), N16 — Renal tubulo-interstitial disorders in diseases classified elsewhere (via C92.-), R50.81 — Fever presenting with conditions classified elsewhere (via C92.-), Z15.0 — Genetic susceptibility to malignant neoplasm (via C92.-).

Each of these codes carries a Code First note naming this condition — when that code is reported, THIS code is sequenced first, ahead of it.
