Cutaneous T-cell lymphoma, unspecified, unspecified site

This code represents a malignant neoplasm of T-lymphocytes that primarily affects the skin, without further specification of the particular subtype of cutaneous T-cell lymphoma (CTCL). It indicates a primary skin lymphoma originating from T-cells, where the specific classification of the CTCL is not documented.

Use this code when the medical record clearly states a diagnosis of cutaneous T-cell lymphoma, but the specific type (e.g., Mycosis Fungoides, Sezary Syndrome) is not identified or documented. This code is appropriate when the physician's diagnosis is simply "cutaneous T-cell lymphoma" without further detail regarding the specific subtype or anatomical location.

• Avoid using this code if a more specific type of cutaneous T-cell lymphoma is documented (e.g., Mycosis Fungoides, Sezary Syndrome), as more specific codes exist.
• Query the provider for clarification on the specific subtype of CTCL if possible, to allow for more precise coding.
• This code also indicates an unspecified anatomical site, so if a specific site is documented, a more precise code should be sought.
