Coder workflow for D24

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

Before you code D24

  1. D24 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).

    ReviewD24.1, D24.2, D24.9

    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 benign 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 →

Choose the right path

  1. Does the documentation support one of the more specific codes beneath D24?
    Yes → Select that code and continue the checks below on its own page.
    No → D24 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewD24.1, D24.2, D24.9

Consider D24. 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).
Anatomical site
At the most specific level the record states; a site the classification separates cannot be assumed from a procedure or a measurement.
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

  • Excludes2 — not part of D24(5 notes)

    Coding workflow: The conditions named in this note are not included in D24. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareN60.2, N60, D22.5, D23.5

    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.

Relationships & Classification

MedCoder-derived relationships — computed from published CMS and AHRQ datasets

Other codes that name D24 or its code family, from the CMS ICD-10-CM tabular instructional notes, the CMS Table of Neoplasms and the CMS Table of Neoplasms (site match derived from the code title). Tabular-note edges are stored at the code family level that carries each note.

Referenced by 1 Excludes1 note: D21 — Other benign neoplasms of connective and other soft tissue.

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: N60.2 — Fibroadenosis of breast.

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