Valid Values

Notes

Note 1 *• Physician Statement*

  • Physician statement indicating the presence or absence of extranodal extension (ENE) can be used to code this data item when no other information is available

  • Physical exam alone is sufficient to determine Clinical ENE

Note 2 Clinical assessment criteria

  • The assessment of ENE must be based on evidence acquired prior to definitive surgery of the primary site, chemotherapy, radiation, or other type of treatment, i.e., the clinical timeframe for staging.

  • The assessment for ENE may include imaging and/or physical examination.

  • Biopsy of the regional lymph node or surrounding tissue can be used to confirm the presence of metastatic carcinoma and thus verify the clinical assessment, but cannot be used in isolation to determine ENE during clinical staging

  • Fixed nodes are clinical indications of cENE

  • Matted nodes are indications of iENE

  • iENE is identified exclusively on imaging

  • ENE during clinical staging is considered present when cENE and/or iENE are present

  • Note that the rules for coding ENE for head and neck sites compared to non-head and neck sites are different
