HCC Category Mapping

What This Code Means

A rare type of blood cancer where cancer cells develop from red blood cell precursors and the cancer has responded to treatment.

Coding Tips

• •Confirm pathology diagnosis of acute erythroid leukemia; this is a rare subtype requiring specific identification
• •The fifth character '1' indicates remission; document the remission status clearly in the medical record

Clinical Significance

Acute erythroid leukemia in remission indicates this rare erythroid-lineage leukemia has responded to intensive chemotherapy. Given the rarity and aggressive nature of this subtype, achieving remission often requires combination chemotherapy similar to other acute myeloid leukemia protocols, and long-term survival remains guarded.

Documentation Requirements

• ✓Documentation must explicitly confirm remission, supported by bone marrow biopsy showing less than 5% blasts and normalized erythropoiesis.
• ✓The specific remission criteria met (complete vs.
• ✓partial), date of remission, and ongoing surveillance or consolidation therapy plan must be recorded.
