Cutaneous T-cell lymphoma, unsp, intrapelvic lymph nodes

This code signifies a diagnosis of cutaneous T-cell lymphoma (CTCL) where the specific type of CTCL is not documented, and the disease has metastasized to or originated in the intrapelvic lymph nodes. CTCL is a rare type of non-Hodgkin lymphoma that primarily affects the skin but can spread to lymph nodes and other organs.

Use this code when documentation confirms a diagnosis of CTCL with involvement of the intrapelvic lymph nodes, but the specific subtype of CTCL (e.g., Mycosis fungoides, Sezary syndrome) is not specified. This code is appropriate when pathology reports or physician notes clearly indicate intrapelvic lymph node involvement.

• Ensure the documentation explicitly states "intrapelvic lymph nodes" and not just "pelvic lymph nodes" if a more specific site is known.
• Do not use this code if a specific subtype of cutaneous T-cell lymphoma is identified; instead, use the more specific code for that subtype.
• Always sequence this code after the primary malignancy if the intrapelvic lymph node involvement is a secondary site.
