D46.2 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of refractory anemia with excess of blasts [raeb]. 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 Refractory anemia with excess of blasts [RAEB]

Non-specific codes like D46.2 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 refractory anemia with excess of blasts [raeb]:

  • Use D46.20 for Refractory anemia with excess of blasts, unspecified - BILLABLE CODE

  • Use D46.21 for Refractory anemia with excess of blasts 1 - BILLABLE CODE

  • Use D46.22 for Refractory anemia with excess of blasts 2 - BILLABLE CODE

Patient Education


Myelodysplastic Syndromes

Your bone marrow is the spongy tissue inside some of your bones, such as your hip and thigh bones. It contains immature cells, called stem cells. The stem cells can develop into the red blood cells that carry oxygen through your body, the white blood cells that fight infections, and the platelets that help with blood clotting. If you have a myelodysplastic syndrome, the stem cells do not mature into healthy blood cells. Many of them die in the bone marrow. This means that you do not have enough healthy cells, which can lead to infection, anemia, or easy bleeding.

Myelodysplastic syndromes often do not cause early symptoms and are sometimes found during a routine blood test. If you have symptoms, they may include:

  • Shortness of breath
  • Weakness or feeling tired
  • Skin that is paler than usual
  • Easy bruising or bleeding
  • Pinpoint spots under the skin caused by bleeding
  • Fever or frequent infections

Myelodysplastic syndromes are rare. People at higher risk are over 60, have had chemotherapy or radiation therapy, or have been exposed to certain chemicals. Treatment options include transfusions, drug therapy, chemotherapy, and blood or bone marrow stem cell transplants.
