ICD-10 Code C81.74 – Other Hodgkin lymphoma, lymph nodes of axilla and upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.74 – Other Hodgkin lymphoma, lymph nodes of axilla and upper limb
What it is
This code identifies Hodgkin lymphoma classified as “other” and documented in lymph nodes of the axilla or upper limb. Use it when the record specifies this nodal location.
Clinical signs
Typical findings include enlarged, firm lymph nodes in the armpit or upper arm region, sometimes with painless swelling. Clinical features vary; refer to documentation.
When to use this code
Use C81.74 when the provider documents other Hodgkin lymphoma involving axillary or upper-limb lymph nodes. It may appear in pathology, oncology, or discharge documentation. If the site is described only as lymph node involvement without this location, check documentation.
Do not use for
Do not use this code for Hodgkin lymphoma in other lymph node regions or for unspecified nodal disease. Do not assign it when the record does not clearly support axilla or upper-limb involvement.
Coding tip
Confirm both the Hodgkin lymphoma type and the documented nodal site before coding.
