2025 ICD-10-CM code D46

Myelodysplastic syndromes. Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

Use additional code to identify any drug-induced adverse effects.Do not use D46 for drug-induced aplastic anemia (D61.1) or neoplasms of unspecified behavior (D49.-).

Medical necessity for MDS treatment is established by the diagnosis confirmed through bone marrow studies and blood tests.The specific treatment approach is determined by the subtype of MDS, the severity of symptoms (cytopenias), and the patient's overall health status.

Physicians diagnose MDS based on patient history, symptoms, physical exam, and laboratory tests including complete blood count (CBC), peripheral blood smear, bone marrow aspiration and biopsy. Genetic testing may also be performed. Treatment can include supportive care (transfusions, medications to stimulate blood cell production), bone marrow transplant, and medications to suppress the immune system or treat infections.

IMPORTANT:Consider additional codes from Chapter 4 to specify any associated functional activity.

In simple words: Myelodysplastic syndromes are bone marrow diseases where the body doesn't make enough healthy blood cells.Instead, it produces immature, abnormal blood cells that don't function properly.Common symptoms include fatigue, shortness of breath, easy bruising or bleeding, and frequent infections.

Myelodysplastic syndromes (MDS) are a group of cancers in which immature blood cells in the bone marrow do not mature and therefore do not develop into healthy blood cells.This leads to a deficiency of one or more types of blood cells: red blood cells (causing anemia), white blood cells (increasing risk of infection), and platelets (causing bleeding disorders).

Example 1: A 70-year-old male presents with fatigue, pallor, and shortness of breath.Blood tests reveal anemia, and a bone marrow biopsy confirms a diagnosis of MDS., A 55-year-old female with a history of breast cancer treated with chemotherapy and radiation now presents with recurrent infections.A bone marrow biopsy reveals MDS., A 65-year-old male experiences easy bruising and prolonged bleeding after minor injuries.Blood tests show thrombocytopenia, and MDS is diagnosed following a bone marrow examination.

Documentation should include complete blood count (CBC) with differential, peripheral blood smear, bone marrow aspiration and biopsy results, cytogenetic analysis, and any relevant genetic testing.Clinical findings such as fatigue, shortness of breath, easy bruising, bleeding, and infections should also be documented.

** MDS is classified by cell morphology and the percentage of blasts (immature cells) in the bone marrow. Several subtypes of MDS exist, with varying prognoses.Treatment options and prognosis are influenced by the subtype, risk factors (prior chemotherapy or radiation exposure), the patient's age, and overall health.
