Cutaneous T-cell lymphoma, unspecified, spleen

This code signifies a diagnosis of cutaneous T-cell lymphoma (CTCL) where the specific subtype of CTCL is not documented, and there is confirmed involvement of the spleen. CTCL is a type of non-Hodgkin lymphoma that primarily affects the skin, but can spread to other organs, including the spleen.

Use this code when documentation clearly states a diagnosis of cutaneous T-cell lymphoma, but the specific type (e.g., Mycosis Fungoides, Sézary Syndrome) is not specified, and splenic involvement is confirmed through imaging, biopsy, or clinical findings. This code is appropriate when the primary site of the lymphoma is the skin, but metastatic or disseminated disease affects the spleen.

• Ensure documentation explicitly states "cutaneous T-cell lymphoma" and "spleen involvement."
• Do not use this code if a more specific subtype of CTCL (e.g., Mycosis Fungoides) is documented; instead, use the appropriate code for that specific subtype with splenic involvement.
• Confirm that the splenic involvement is due to the lymphoma and not an unrelated condition.
