CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

D47 is a non-billable ICD-10-CM category code for other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D47.01, D47.02, D47.09, and D47.1.

Specific Coding for Oth neoplm of uncrt behav of lymphoid, hematpoetc & rel tissOverview

Non-specific codes like D47 require more characters. Use one of these billable codes instead:

  • D47.0 for Mast cell neoplasms of uncertain behavior

  • Use D47.01 for Cutaneous mastocytosis

  • Use D47.02 for Systemic mastocytosis

  • Use D47.09 for Other mast cell neoplasms of uncertain behavior

  • Use D47.1 for Chronic myeloproliferative disease

  • Use D47.2 for Monoclonal gammopathy

  • Use D47.3 for Essential (hemorrhagic) thrombocythemia

  • Use D47.4 for Osteomyelofibrosis

  • Use D47.9 for Neoplasm of uncertain behavior of lymphoid, hematopoietic and related tissue, unspecified

  • D47.Z for Other specified neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue

  • Use D47.Z1 for Post-transplant lymphoproliferative disorder (PTLD)

  • Use D47.Z2 for Castleman disease

  • Use D47.Z9 for Other specified neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D47: its own notes plus those printed at block D37-D48 and Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block D37-D48 Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes applies to 137 codes
  • neoplasms of unspecified behavior (D49.-)

Notes

General instructions on how these codes are used.

From Block D37-D48 Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes applies to 137 codes
  • Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • Functional activity
  • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
  • Morphology [Histology]
  • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
  • Primary malignant neoplasms overlapping site boundaries
  • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
  • Malignant neoplasm of ectopic tissue
  • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Blood Disorders

Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.

Questions About D47Overview

Is D47 a billable code?

No. This is a category header that groups the codes for other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue, and headers cannot be submitted on claims. Claims for other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue need a more specific code from this category, such as D47.01, D47.02, and D47.09.

Can D47 be reported with a code from D49?

Not as a rule. The Excludes1 note at block D37-D48, which applies to D47, lists "neoplasms of unspecified behavior (D49.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
