C92.Z1

HCC Category Mapping

What This Code Means

A rare or unspecified type of myeloid leukemia (blood cancer) where the cancer is currently in remission following treatment.

Coding Tips

• •The 'Z' indicates 'other' myeloid leukemia types; document the specific characteristics that prevent classification into standard subtypes
• •The '1' suffix indicates remission status; ensure clinical documentation confirms absence of detectable disease

Clinical Significance

Other myeloid leukemia in remission indicates a rare myeloid leukemia subtype that has responded to treatment with no detectable disease. Remission status in these atypical subtypes still requires ongoing surveillance given the potential for relapse and the limited clinical data available for uncommon variants.

Documentation Requirements

• ✓Documentation must explicitly state remission and should include the basis for remission determination, such as bone marrow biopsy showing less than 5% blasts, normalized blood counts, or molecular remission markers.
• ✓The specific type of myeloid leukemia and ongoing surveillance or maintenance therapy plan should be noted.
