A type of Hodgkin lymphoma with mixed cellularity affecting lymph nodes in the armpits and upper arms.
Coding Tips
- •Ensure documentation specifies axilla and/or upper limb lymph node involvement
- •Distinguish from other lymph node sites to select the correct fifth character
Clinical Significance
Mixed cellularity Hodgkin lymphoma of axillary and upper limb lymph nodes indicates involvement of the armpit and upper extremity lymph nodes. This peripheral lymph node presentation may be part of multi-site disease or an isolated finding. Mixed cellularity at this site requires pathologic distinction from other lymphoma subtypes and reactive conditions that cause axillary lymphadenopathy.
Documentation Requirements
- ✓Pathology confirming mixed cellularity subtype
- ✓Physical exam and/or imaging documenting axillary or upper limb involvement
- ✓Laterality documented
- ✓Complete staging workup to assess for disease elsewhere
- ✓B-symptoms assessment
- ✓Treatment plan
