Cutaneous follicle center lymphoma, intrapelvic lymph nodes

This code signifies a specific type of non-Hodgkin lymphoma, cutaneous follicle center lymphoma, when it has metastasized or originated in the lymph nodes located within the pelvic region. It indicates a primary or secondary involvement of intrapelvic lymph nodes by this particular indolent B-cell lymphoma.

Use this code when documentation clearly states a diagnosis of cutaneous follicle center lymphoma affecting intrapelvic lymph nodes. This typically arises from pathology reports confirming the lymphoma subtype and imaging or biopsy results indicating pelvic lymph node involvement.

• Ensure the documentation specifies "cutaneous follicle center lymphoma" and not another subtype of follicle center lymphoma.
• Verify that the affected lymph nodes are explicitly identified as "intrapelvic" or within the pelvic region.
• Do not confuse with other sites of cutaneous follicle center lymphoma (e.g., skin, extranodal sites outside the pelvis).
