C92.A2

HCC Category Mapping

What This Code Means

A type of acute blood cancer (myeloid leukemia) where bone marrow cells show abnormal development across multiple cell lines and the cancer has returned after treatment.

Coding Tips

• •The 'A' in C92.A indicates multilineage dysplasia, which is a specific subtype requiring documentation in the medical record
• •The '2' suffix indicates relapse status; ensure treatment records confirm the cancer has recurred after achieving remission

Clinical Significance

Acute myeloid leukemia with multilineage dysplasia in relapse represents a particularly aggressive form of blood cancer where malignant blasts have recurred after prior remission, indicating treatment resistance. The multilineage dysplasia component signals that abnormal cell development spans erythroid, granulocytic, and megakaryocytic lineages, conferring a worse prognosis than standard acute myeloid leukemia subtypes.

Documentation Requirements

• ✓Documentation must confirm the specific subtype of acute myeloid leukemia with multilineage dysplasia via pathology or bone marrow biopsy findings.
• ✓The relapse status requires evidence of prior remission followed by recurrence, including dates of remission achievement and relapse detection, current blast percentage, and ongoing or planned salvage therapy.
