Subcutaneous panniculitis-like T-cell lymphoma, in remission

This code signifies a diagnosis of subcutaneous panniculitis-like T-cell lymphoma (SPTCL) that is currently in remission. SPTCL is a rare, aggressive form of non-Hodgkin lymphoma characterized by infiltration of the subcutaneous fat by malignant T-cells, often mimicking panniculitis. Remission indicates a period where the signs and symptoms of the lymphoma have significantly decreased or disappeared.

This code is appropriate when documentation explicitly states that a patient has a history of SPTCL and is currently in a state of remission. It should be used for follow-up encounters, surveillance, or when the patient is receiving ongoing treatment for maintenance of remission. Supporting documentation would include pathology reports confirming the initial diagnosis and physician notes indicating the current remission status.

• Ensure documentation clearly specifies "in remission" for SPTCL; do not use for active disease or unspecified status.
• Do not confuse with other types of cutaneous T-cell lymphomas or non-lymphoma panniculitis.
• Sequence this code as a secondary diagnosis if the encounter is for a complication or sequela of the lymphoma, or for treatment of another unrelated condition.
