Code Classification

  • Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism
    • Other disorders of blood and blood-forming organs
      • Other disorders of white blood cells

D72.1 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of eosinophilia. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Eosinophilia

Non-specific codes like D72.1 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for eosinophilia:

  • Use D72.10 for Eosinophilia, unspecified - BILLABLE CODE

  • D72.11 for Hypereosinophilic syndrome [HES] - NON-BILLABLE CODE

  • Use D72.110 for Idiopathic hypereosinophilic syndrome [IHES] - BILLABLE CODE

  • Use D72.111 for Lymphocytic Variant Hypereosinophilic Syndrome [LHES] - BILLABLE CODE

  • Use D72.118 for Other hypereosinophilic syndrome - BILLABLE CODE

  • Use D72.119 for Hypereosinophilic syndrome [HES], unspecified - BILLABLE CODE

  • Use D72.12 for Drug rash with eosinophilia and systemic symptoms syndrome - BILLABLE CODE

  • Use D72.18 for Eosinophilia in diseases classified elsewhere - BILLABLE CODE

  • Use D72.19 for Other eosinophilia - BILLABLE CODE

Clinical Classification

Clinical Information

  • Eosinophilia

    abnormal increase of eosinophils in the blood, tissues or organs.
  • Eosinophilia-Myalgia Syndrome

    a complex systemic syndrome with inflammatory and autoimmune components that affect the skin, fascia, muscle, nerve, blood vessels, lung, and heart. diagnostic features generally include eosinophilia, myalgia severe enough to limit usual activities of daily living, and the absence of coexisting infectious, autoimmune or other conditions that may induce eosinophilia. biopsy of affected tissue reveals a microangiopathy associated with diffuse inflammation involving connective tissue. (from spitzer et al., j rheumatol suppl 1996 oct;46:73-9; blackburn wd, semin arthritis rheum 1997 jun;26(6):788-93)
  • Pulmonary Eosinophilia

    a condition characterized by infiltration of the lung with eosinophils due to inflammation or other disease processes. major eosinophilic lung diseases are the eosinophilic pneumonias caused by infections, allergens, or toxic agents.
  • Eosinophils

    granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • pulmonary eosinophilia J82

Patient Education

Eosinophilic Disorders

Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body's immune response. They can also build up and cause inflammation.

Normally your blood doesn't have a large number of eosinophils. Your body may produce more of them in response to:

  • Allergic disorders
  • Skin conditions
  • Parasitic and fungal infections
  • Autoimmune diseases
  • Some cancers
  • Bone marrow disorders

In some conditions, the eosinophils can move outside the bloodstream and build up in organs and tissues. This can happen in many different parts of the body, including the esophagus, heart, lungs, blood, and intestines. Treatment of eosinophilic disorders can vary, depending on the cause and which part of the body is affected. Steroids are often part of the treatment.
