Coder workflow for D27

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

Before you code D27

  1. D27 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).

    ReviewD27.0, D27.1, D27.9

    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 D27?
    Yes → Select that code and continue the checks below on its own page.
    No → D27 cannot be reported as written. Where the codes beneath it include an unspecified code, that code applies when the record goes no further; otherwise query for the missing detail.

    ReviewD27.0, D27.1, D27.9

Report the code beneath D27 that the documentation supports, not D27 itself. Then work the Use Additional Code note, and confirm that code is valid for the date of service on its own page.

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.
The conditions the Use Additional Code note names
Reported with this code when documented; a conditional instruction (“if applicable”, “if known”) applies only when the record supports it.
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 D27(7 notes)

    Coding workflow: The conditions named in this note are not included in D27. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareN83.2, N83.1, N80.1, N83.0

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

  • Use Additional Code — after identifying D27(1 note)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with D27 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

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

Coding decision scenarios

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

Documentation: A condition the Use Additional Code note names is documented.

Coding question: Is a second code reported with the code beneath D27?

Path: Review the Use Additional Code note and the code it names.

Reason: The additional code is reported when the record documents the condition; a conditional instruction applies only when its condition is met (Guidelines I.A.13).

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.
