Subcutaneous panniculitis-like T-cell lymphoma not remission

This code signifies a rare, aggressive form of non-Hodgkin lymphoma characterized by the infiltration of subcutaneous fat by atypical T-cells, mimicking panniculitis. It specifically indicates that the disease is currently active and has not yet responded to treatment sufficiently to be considered in remission.

Apply this code when documentation confirms a diagnosis of subcutaneous panniculitis-like T-cell lymphoma (SPTCL) and explicitly states that the patient has not achieved remission. This typically applies to initial diagnoses, ongoing active disease, or recurrence where remission has not been re-established. Supporting documentation includes pathology reports, oncologist notes, and treatment summaries.

• Differentiate from other cutaneous T-cell lymphomas; SPTCL has distinct clinical and pathological features.
• Ensure documentation clearly states "not having achieved remission" to avoid miscoding for remission status.
• Sequence as a primary diagnosis when it is the reason for the encounter or treatment.
