Valid for Submission
C94.30 is a billable diagnosis code used to specify a medical diagnosis of mast cell leukemia not having achieved remission. The code C94.30 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code C94.30 might also be used to specify conditions or terms like aleukemic leukemia, aleukemic mast cell leukemia, malignant white blood cell disorder, mast cell leukemia , mast cell leukemia affecting skin , systemic mast cell disease, etc.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C94.30:
Inclusion TermsInclusion Terms
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.
- Mast cell leukemia with failed remission
- Mast cell leukemia NOS
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Aleukemic leukemia
- Aleukemic mast cell leukemia
- Malignant white blood cell disorder
- Mast cell leukemia
- Mast cell leukemia affecting skin
- Systemic mast cell disease

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert C94.30 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C94.30 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
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:
- White blood cells help your body fight infection
- Red blood cells deliver oxygen from your lungs to your tissues and organs
- Platelets help form clots to stop bleeding
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 are the types of leukemia?
There are different types of leukemia. Which type of leukemia you have depends on the type of blood cell that becomes cancer and whether it grows quickly or slowly.
The type of blood cell could be
- Lymphocytes, a type of white blood cell
- Myeloid cells, immature cells that become white blood cells, red blood cells, or platelets
The different types can grow quickly or slowly:
- Acute leukemia is fast growing. It usually gets worse quickly if it's not treated.
- Chronic leukemia is slow growing. It usually gets worse over a longer period of time.
The main types of leukemia are
- Acute lymphocytic leukemia (ALL), which is the most common type of cancer in children. It can also affect adults.
- Acute myeloid leukemia (AML), which is more common in older adults but can also affect children
- Chronic lymphocytic leukemia (CLL), which is one of the most common types of leukemia in adults. It often occurs during or after middle age.
- Chronic myeloid leukemia (CML), which usually occurs in adults during or after middle age
What causes leukemia?
Leukemia happens when there are changes in the genetic material (DNA) in bone marrow cells. The cause of these genetic changes is unknown.
Who is at risk for leukemia?
For the specific types, there are different factors which can raise your risk of getting that type. Overall, your risk of leukemia goes up as you age. It is most common over age 60.
What are the symptoms of leukemia?
Some of the symptoms of leukemia may include
- Feeling tired
- Fever or night sweats
- Easy bruising or bleeding
- Weight loss or loss of appetite
- Petechiae, which are tiny red dots under the skin. They are caused by bleeding.
Other leukemia symptoms can be different from type to type. Chromic leukemia may not cause symptoms at first.
How is leukemia diagnosed?
Your health care provider may use many tools to diagnose leukemia:
- A physical exam
- A medical history
- Blood tests, such as a complete blood count (CBC)
- Bone marrow tests. There are two main types - bone marrow aspiration and bone marrow biopsy. Both tests involve removing a sample of bone marrow and bone. The samples are sent to a lab for testing.
- Genetic tests to look for gene and chromosome changes
Once the provider makes a diagnosis, there may be 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 leukemia?
The treatments for leukemia depend on which type you have, how severe the leukemia is, your age, your overall health, and other factors. Some possible treatments might include
- Radiation therapy
- Chemotherapy with stem cell transplant
- Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells
