Hodgkin lymphoma (C81) ICD-10-CM
The C81 code range covers hodgkin lymphoma with 85 ICD-10-CM diagnosis codes. 77 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the C81 range.
Lymphomatoid Papulosis
Clinically benign, histologically malignant, recurrent cutaneous T-cell lymphoproliferative disorder characterized by an infiltration of large atypical cells surrounded by inflammatory cells. The atypical cells resemble REED-STERNBERG CELLS of HODGKIN DISEASE or the malignant cells of CUTANEOUS T-CELL LYMPHOMA. In some cases, lymphomatoid papulosis progresses to lymphomatous conditions including MYCOSIS FUNGOIDES; HODGKIN DISEASE; CUTANEOUS T-CELL LYMPHOMA; or ANAPLASTIC LARGE-CELL LYMPHOMA.
About the C81 Code Range
ICD-10 code C81 covers all forms of Hodgkin lymphoma, a type of cancer originating in the lymphatic system. This section categorizes Hodgkin lymphoma by specific subtypes and anatomic locations, enabling precise coding for diagnosis, treatment, and remission status.
The codes include detailed distinctions such as C81.0 for nodular lymphocyte predominant Hodgkin lymphoma—often referred to as "Hodgkin's disease, nodular sclerosis - lymphocytic predominance"—and C81.1 for nodular sclerosis type, among others. Each subtype further breaks down by lymph node regions like head and neck (C81.01, C81.11, etc.), intrathoracic nodes (C81.02, C81.12), or spleen involvement (C81.07, C81.17), assisting coders in specifying location and histologic details. Synonyms included for many codes help clarify common clinical terms linked to these diagnoses, supporting accurate medical coding. Additionally, remission status codes (e.g., C81.0A, C81.1A) indicate when the disease is inactive.
For health professionals and coders, understanding these distinctions within the ICD-10 code for Hodgkin lymphoma is essential for correctly assigning codes based on subtype, site, and disease progression, which ultimately facilitates clearer communication and appropriate care delivery.
