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

D70 is a non-billable ICD-10-CM category code for neutropenia, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D70.0, D70.1, D70.2, and D70.3.

Specific Coding for NeutropeniaOverview

Non-specific codes like D70 require more characters. Use one of these billable codes instead:

  • Use D70.0 for Congenital agranulocytosis

  • Use D70.1 for Agranulocytosis secondary to cancer chemotherapy

  • Use D70.2 for Other drug-induced agranulocytosis

  • Use D70.3 for Neutropenia due to infection

  • Use D70.4 for Cyclic neutropenia

  • Use D70.8 for Other neutropenia

  • Use D70.9 for Neutropenia, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D70: its own notes plus those printed at Chapter 3. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • agranulocytosis
  • decreased absolute neurophile count (ANC)

Excludes1

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

  • neutropenic splenomegaly (D73.81)
  • transient neonatal neutropenia (P61.5)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 3 (D50-D89) Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism applies to 324 codes
  • autoimmune disease (systemic) NOS (M35.9)
  • certain conditions originating in the perinatal period (P00-P96)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • human immunodeficiency virus [HIV] disease (B20)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • code for any associated:
  • fever (R50.81)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

Referenced in Other NotesGuidance

Instructional notes printed at other codes that name D70, its category, or a range that includes it.

Excludes2 4

These codes carry an Excludes2 note naming D70: its condition is not part of those codes, and both may be reported when the patient has both.

  • D61 Other aplastic anemias and other bone marrow failure syndromes
    neutropenia (D70.-)
  • D72 Other disorders of white blood cells
    neutropenia (D70)
  • D72.81 Decreased white blood cell count
    neutropenia (D70)
  • Block R70-R79 Abnormal findings on examination of blood, without diagnosis
    abnormalities of white blood cells classified elsewhere (D70-D72)

Code First 1

These codes say to code first a condition named in the note, and D70 is one of the conditions named.

  • R50.81 Fever presenting with conditions classified elsewhere
    neutropenia (D70.-)

Clinical InformationClinical

  • Neutropenia

    a decrease in the number of neutrophils found in the blood.

Patient EducationClinical

Anemia

If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.

Questions About D70Overview

What is the ICD-10 code for neutropenia?

D70 is the ICD-10-CM category for neutropenia, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is D70 (Neutropenia) a billable code?

No. This is a category header that groups the codes for neutropenia, and headers cannot be submitted on claims. Claims for neutropenia need a more specific code from this category, such as D70.0, D70.1, and D70.2.

Can D70 be reported with D73.81?

Not as a rule. The Excludes1 note on D70 lists "neutropenic splenomegaly (D73.81)". 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).

Does D70 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code for any associated: fever (R50.81). The additional code is reported after D70.
