Mycosis fungoides, in remission

This code signifies that a patient with mycosis fungoides, a type of cutaneous T-cell lymphoma, is currently experiencing a period of no detectable disease activity or symptoms. It indicates that the cancer is no longer active and the patient is in a stable, disease-free state following treatment.

Use this code when documentation explicitly states "mycosis fungoides in remission" or similar phrasing indicating the absence of active disease. This applies to patients who have undergone treatment and are now being monitored for recurrence. Supporting documentation would include pathology reports confirming the initial diagnosis and physician notes confirming the current remission status.

• Do not use this code for active mycosis fungoides; refer to codes within C84.00-C84.09 for active disease.
• Always confirm the specific type of cutaneous T-cell lymphoma if documented, as other types have different codes.
• Sequence this code as a secondary diagnosis if the patient is being seen for a complication or follow-up related to the mycosis fungoides, but the primary reason for the encounter is not the remission itself.
