C93.90 - Monocytic leukemia, unspecified, not having achieved remission

Version 2023
ICD-10:C93.90
Short Description:Monocytic leukemia, unsp, not having achieved remission
Long Description:Monocytic leukemia, unspecified, not having achieved remission
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96)
      • Monocytic leukemia (C93)

C93.90 is a billable ICD-10 code used to specify a medical diagnosis of monocytic leukemia, unspecified, not having achieved remission. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

Unspecified diagnosis codes like C93.90 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Acute Myeloid Leukemia

What is leukemia?

Leukemia is a term for cancers of the blood cells. Leukemia starts in blood-forming tissues such as the bone marrow. Your bone marrow makes the cells which will develop into white blood cells, red blood cells, and platelets. Each type of cell has a different job:

When you have leukemia, your bone marrow makes large numbers of abnormal cells. This problem most often happens with white blood cells. These abnormal cells build up in your bone marrow and blood. They crowd out the healthy blood cells and make it hard for your cells and blood to do their work.

What is acute myeloid leukemia (AML)?

Acute myeloid leukemia (AML) is a type of acute leukemia. "Acute" means that the leukemia usually gets worse quickly if it's not treated. In AML, the bone marrow makes abnormal myeloblasts (a type of white blood cell), red blood cells, or platelets. When the abnormal cells crowd out the healthy cells, it can lead to infection, anemia, and easy bleeding. The abnormal cells can also spread outside the blood to other parts of the body.

There are several different subtypes of AML. The subtypes are based on how developed the cancer cells are when you get your diagnosis and how different they are from normal cells.

What causes acute myeloid leukemia (AML)?

AML happens when there are changes in the genetic material (DNA) in bone marrow cells. The cause of these genetic changes is unknown. However, there are certain factors that raise your risk of AML.

Who is at risk for acute myeloid leukemia (AML)?

The factors that raise your risk of AML include:

What are the symptoms of acute myeloid leukemia (AML)?

The signs and symptoms of AML include:

How is acute myeloid leukemia (AML) diagnosed?

Your health care provider may use many tools to diagnose AML and figure out which subtype you have:

If you are diagnosed with AML, you may have additional tests to see whether the cancer has spread. These include imaging tests and a lumbar puncture, which is a procedure to collect and test cerebrospinal fluid (CSF).

What are the treatments for acute myeloid leukemia (AML)?

Treatments for AML include:

Which treatment you get often depends on which subtype of AML you have. Treatment is usually done in two phases:

Chronic Myeloid Leukemia

What is leukemia?

Leukemia is a term for cancers of the blood cells. Leukemia starts in blood-forming tissues such as the bone marrow. Your bone marrow makes the cells which will develop into white blood cells, red blood cells, and platelets. Each type of cell has a different job:

When you have leukemia, your bone marrow makes large numbers of abnormal cells. This problem most often happens with white blood cells. These abnormal cells build up in your bone marrow and blood. They crowd out the healthy blood cells and make it hard for your cells and blood to do their work.

What is chronic myeloid leukemia (CML)?

Chronic myeloid leukemia (CML) is a type of chronic leukemia. "Chronic" means that the leukemia usually gets worse slowly. In CML, the bone marrow makes abnormal granulocytes (a type of white blood cell). These abnormal cells are also called blasts. When the abnormal cells crowd out the healthy cells, it can lead to infection, anemia, and easy bleeding. The abnormal cells can also spread outside the blood to other parts of the body.

CML usually occurs in adults during or after middle age. It is rare in children.

What causes chronic myeloid leukemia (CML)?

Most people with CML have a genetic change called the Philadelphia chromosome. It's called that because researchers in Philadelphia discovered it. People normally have 23 pairs of chromosomes in each cell. These chromosomes contain your DNA (genetic material). In CML, part of the DNA from one chromosome moves to another chromosome. It combines with some DNA there, which creates a new gene called BCR-ABL. This gene causes your bone marrow to make an abnormal protein. This protein allows the leukemia cells to grow out of control.

The Philadelphia chromosome isn't passed from parent to child. It happens during your lifetime. The cause is unknown.

Who is at risk for chronic myeloid leukemia (CML)?

It is hard to predict who will get CML. There are a few factors that could raise your risk:

What are the symptoms of chronic myeloid leukemia (CML)?

Sometimes CML does not cause symptoms. If you do have symptoms, they can include:

How is chronic myeloid leukemia (CML) diagnosed?

Your health care provider may use many tools to diagnose CML:

If you are diagnosed with CML, you may have additional tests such as imaging tests to see whether the cancer has spread.

What are the phases of chronic myeloid leukemia (CML)?

CML has three phases. The phases are based on how much the CML has grown or spread:

What are the treatments for chronic myeloid leukemia (CML)?

There are several different treatments for CML:

Which treatments you get will depend on which phase you are in, your age, your overall health, and other factors. When the signs and symptoms of CML are reduced or have disappeared, it is called remission. The CML may come back after remission, and you may need more treatment.
