Coding instructions
Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for D47 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 D47 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).

Coder workflow for D47
MedCoder structured workflow — derived from this code’s own official record
Before you code D47
- D47 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).
ReviewD47.0, D47.1, D47.2, D47.3, D47.4, D47.9, D47.Z
See the relationships section · Guide: How to choose an ICD-10-CM code →
- “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on D47; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).
See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →
- Confirm the documented site and behavior (this code’s block classifies uncertain behavior 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 →
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with D47. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).
Choose the right path
- Does the documentation support one of the more specific codes beneath D47?
Yes → Select that code and continue the checks below on its own page.
No → D47 cannot be reported as written; query for the specificity its subcategory needs. - Does the documentation support a condition named in D47’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.ReviewD49
Consider D47. 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).
- Any detail beyond this code’s title
- What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.
Official instructions as workflow
Excludes1 — check before selecting D47(1 note)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with D47: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: Both the condition D47 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).
ReviewD49
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.

Common coding questions
Can D47 be billed directly?
No. D47 (Other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
