ICD-10 Code C82.32 – Follicular lymphoma grade IIIa, intrathoracic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.32 – Follicular lymphoma grade IIIa, intrathoracic lymph nodes
What it is
C82.32 identifies follicular lymphoma, grade IIIa, involving intrathoracic lymph nodes. Use it when documentation specifies this lymphoma subtype and nodal location.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include enlarged intrathoracic lymph nodes on imaging or biopsy confirmation of follicular lymphoma grade IIIa.
When to use this code
Use C82.32 when the provider documents follicular lymphoma grade IIIa in intrathoracic lymph nodes, such as mediastinal or hilar involvement. Code it from pathology, oncology, or discharge notes when the site and grade are clearly stated. Check documentation if the report names follicular lymphoma without grade or thoracic nodal location.
Do not use for
Do not use this code for other lymphoma grades, unspecified follicular lymphoma, or disease in non-intrathoracic nodes. Check documentation if the record is ambiguous or lists a different anatomic site.
Coding tip
Confirm both the grade and the intrathoracic nodal site before assigning C82.32.
