Extranodal NK/T-cell lymphoma, nasal type not remission

This code signifies a diagnosis of extranodal NK/T-cell lymphoma, nasal type, which is a rare and aggressive non-Hodgkin lymphoma primarily affecting the nasal cavity and paranasal sinuses. The "not having achieved remission" component indicates that the disease is still active and has not responded to initial treatment or has relapsed.

This code is appropriate for patients diagnosed with extranodal NK/T-cell lymphoma, nasal type, who are currently undergoing treatment, have failed to achieve remission, or have experienced a relapse. Documentation should clearly state the specific lymphoma type, its extranodal nasal presentation, and explicitly indicate that the patient is not in remission.

• Differentiate from other types of NK/T-cell lymphomas or lymphomas in remission; the "nasal type" and "not having achieved remission" are crucial for accurate coding.
• Ensure supporting documentation from pathology reports and physician notes confirms the specific diagnosis and the current disease status.
• Do not use this code if the patient has achieved complete or partial remission; instead, refer to codes indicating remission status.
