ICD-10 Code C82.62 – Cutaneous follicle center lymphoma, intrathoracic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.62 – Cutaneous follicle center lymphoma, intrathoracic lymph nodes
What it is
C82.62 identifies cutaneous follicle center lymphoma involving the intrathoracic lymph nodes. Use it when documentation specifies this lymphoma subtype and nodal site, not a broader lymphoma diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Typical records may note confirmed lymphoma in intrathoracic lymph nodes, often supported by pathology, imaging, or specialist assessment.
When to use this code
Use this code when the provider documents cutaneous follicle center lymphoma with intrathoracic lymph node involvement. It is appropriate for confirmed disease at this site, including staging or follow-up encounters tied to the documented diagnosis.
If the record only states lymphoma without the subtype or nodal location, check documentation before coding. Code the most specific confirmed diagnosis available.
Do not use for
Do not use for unspecified lymphoma, other cutaneous lymphomas, or lymph node disease without documented cutaneous follicle center lymphoma. Check documentation if the site or histology is unclear.
Coding tip
Confirm both the lymphoma subtype and intrathoracic lymph node involvement in the provider note before assigning C82.62.
