0.000What This Code Means
A type of cancer of the lymph system (follicular lymphoma) that is in remission, meaning the cancer is responding to treatment or has resolved.
Coding Tips
- •Only use this code when documentation explicitly states the patient is in remission or complete response
- •This code can be used regardless of the original site of involvement; remission status takes precedence
Clinical Significance
Follicular lymphoma, unspecified type, in remission indicates that a follicular lymphoma of undetermined grade has responded to treatment. Despite the unspecified grade, remission status is clearly documented by the treating physician. This code maintains active cancer diagnosis for risk adjustment during surveillance. The patient requires ongoing monitoring due to the high relapse rate of follicular lymphomas, even when grade is not specified.
Documentation Requirements
- ✓Physician documentation explicitly stating remission
- ✓Most recent imaging confirming no active disease
- ✓Date remission was achieved and type (complete vs. partial)
- ✓Ongoing surveillance plan
- ✓Original pathology report (even if grade was not determined)
- ✓Maintenance therapy documentation if applicable
