ICD-10 Code C82.14 – Follicular lymphoma grade II, lymph nodes of axilla and upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.14 – Follicular lymphoma grade II, lymph nodes of axilla and upper limb
What it is
This code identifies follicular lymphoma, grade II, involving lymph nodes in the axilla or upper limb. It specifies both the lymphoma subtype and the anatomic site documented by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Follicular lymphoma commonly presents with painless, enlarged lymph nodes, and diagnosis is based on pathology with site-specific involvement noted in the record.
When to use this code
Use C82.14 when the provider documents grade II follicular lymphoma affecting lymph nodes of the axilla or upper limb. Apply it when the site is clearly stated in pathology, oncology, or discharge documentation.
If the record names follicular lymphoma but does not specify grade or nodal location, check documentation before coding. Use the most specific code supported by the chart.
Do not use for
Do not use this code for other lymphoma types, unspecified follicular lymphoma, or disease in different nodal regions. Check documentation if the axillary or upper-limb site is not confirmed.
Coding tip
Code the lymphoma grade and node location exactly as documented; if either element is missing, query the record before assigning C82.14.
