Cutaneous T-cell lymphoma, unspecified, in remission

This code represents a diagnosis of cutaneous T-cell lymphoma (CTCL) where the specific subtype is not documented, and the disease is currently in a state of remission. CTCL is a rare type of non-Hodgkin lymphoma that primarily affects the skin, characterized by the proliferation of malignant T-lymphocytes. Remission indicates a significant reduction or disappearance of disease signs and symptoms.

Use this code when documentation confirms a past diagnosis of unspecified cutaneous T-cell lymphoma, and the patient is currently experiencing a period of remission, with no active disease manifestations. This code is appropriate when the medical record explicitly states "in remission" for CTCL without further specification of the lymphoma subtype.

• Ensure documentation clearly specifies "unspecified" CTCL and "in remission."
• Do not use this code if the specific subtype of CTCL (e.g., Mycosis Fungoides, Sezary Syndrome) is documented; instead, use the appropriate specific code.
• Sequence this code as a secondary diagnosis if the patient is being seen for a complication or follow-up related to the history of CTCL, or as a primary diagnosis if the encounter is solely for monitoring the remission status.
