Other Hodgkin lymphoma, extranodal and solid organ sites

This code represents a diagnosis of Hodgkin lymphoma that originates or has spread to sites outside of the lymph nodes, spleen, or thymus, and is not classified as nodular sclerosis, mixed cellularity, lymphocyte-rich, lymphocyte-depleted, or unspecified type. It indicates involvement of solid organs or other extranodal tissues.

Use this code when documentation specifies Hodgkin lymphoma affecting extranodal sites or solid organs, and the specific histological subtype is identified as "other" or not otherwise classifiable to a more specific C81.x subtype. This applies when the physician explicitly states "other Hodgkin lymphoma" with extranodal involvement.

• Ensure the documentation clearly states "extranodal" or "solid organ involvement" in addition to "other Hodgkin lymphoma."
• Do not use this code if a more specific histological subtype (e.g., nodular sclerosis, mixed cellularity) is documented, even with extranodal involvement.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless another condition is specifically identified as the primary reason for treatment.
