What This Code Means

A type of slow-growing blood cancer (follicular lymphoma) that is grade II and is currently in remission (no active disease).

Coding Tips

  • Only use this code when remission status is explicitly documented by the physician
  • Remission may be partial or complete; ensure the documentation specifies which type

Clinical Significance

Follicular lymphoma grade II in remission indicates previously active intermediate-grade disease that has responded to treatment or is in a quiescent phase. Remission does not imply cure in follicular lymphoma — relapse rates are high, and lifelong surveillance is standard. This code captures the ongoing disease burden and monitoring needs even during remission.

Documentation Requirements

  • History of biopsy-proven follicular lymphoma grade II
  • Oncologist documentation explicitly stating complete or partial remission
  • Imaging evidence supporting remission (negative or improved PET/CT)
  • Ongoing surveillance plan with follow-up intervals
  • Duration of remission and any maintenance therapy (e.g., rituximab maintenance)
