Cutaneous T-cell lymphoma, unsp, intra-abdominal lymph nodes

This code signifies a diagnosis of cutaneous T-cell lymphoma (CTCL) where the specific subtype of CTCL is not documented, and the disease has spread to involve the intra-abdominal lymph nodes. CTCL is a rare type of non-Hodgkin lymphoma that primarily affects the skin but can disseminate to other organs, including lymph nodes.

Apply this code when documentation confirms a diagnosis of cutaneous T-cell lymphoma without further specification of the CTCL subtype (e.g., mycosis fungoides, Sezary syndrome) and explicitly states involvement of intra-abdominal lymph nodes. This code is appropriate when the physician's diagnostic statement indicates "cutaneous T-cell lymphoma, unspecified, with intra-abdominal lymph node involvement."

• Ensure documentation clearly specifies "unspecified" cutaneous T-cell lymphoma and intra-abdominal lymph node involvement.
• Do not use this code if a specific subtype of cutaneous T-cell lymphoma (e.g., C84.0-C84.8) is documented.
• Consider sequencing this code after any codes for the primary cutaneous manifestations if still active and being treated.
