C92.92

HCC Category Mapping

What This Code Means

A type of myeloid blood cancer that cannot be more specifically classified and has returned after a period of remission.

Coding Tips

• •Ensure documentation clearly indicates relapse rather than initial presentation or persistent disease
• •Note the timeline between remission and relapse when available

Clinical Significance

Myeloid leukemia, unspecified, in relapse indicates recurrence of an unspecified myeloid leukemia after prior remission. At the relapse stage, the subtype should be well-characterized from prior diagnostic workup, making this unspecified code inappropriate in most clinical situations. Updated diagnostic testing at relapse should allow reclassification to a more specific code.

Documentation Requirements

• ✓Documentation must confirm prior remission and current relapse.
• ✓Updated bone marrow biopsy, cytogenetics, and molecular testing at relapse should be documented and will typically allow reclassification to a specific subtype.
• ✓Prior treatment history, duration of remission, and salvage treatment plan must be recorded.
• ✓Query the provider for subtype clarification if not documented.
