ICD-10 Code C85.94 – Non-Hodgkin lymphoma, unspecified, lymph nodes of axilla and upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.94 – Non-Hodgkin lymphoma, unspecified, lymph nodes of axilla and upper limb
What it is
This code identifies non-Hodgkin lymphoma when the record does not specify the subtype and the involved lymph nodes are in the axilla or upper limb. Use it for documented nodal disease in that anatomic site.
Clinical signs
Typical findings include enlarged, firm, or painless lymph nodes in the armpit or upper arm region. Clinical features vary; refer to documentation for the exact presentation and confirmed nodal location.
When to use this code
Use this code when the provider documents non-Hodgkin lymphoma as unspecified and clearly links it to axillary or upper-limb lymph nodes. It also fits when pathology or imaging supports nodal lymphoma in that location and no more specific lymphoma type is recorded.
Choose this code only when the site is documented as lymph nodes of the axilla or upper limb. If the record names a specific non-Hodgkin lymphoma subtype, code that more specific diagnosis instead.
Do not use for
Do not use this code for Hodgkin lymphoma, other specified non-Hodgkin lymphoma subtypes, or lymphoma in a different nodal region. Check documentation if the involved site is unclear.
Coding tip
Confirm both the unspecified lymphoma type and the exact lymph node site before assigning C85.94.
