0.000What This Code Means
Lymphoblastic lymphoma that is currently in remission, meaning the cancer is no longer detectable or has responded well to treatment.
Coding Tips
- •This code should only be used when documentation explicitly states the patient is in remission or has achieved complete response
- •Ensure remission status is clearly documented in clinical notes; do not assume remission without explicit statement
Clinical Significance
Lymphoblastic lymphoma in remission indicates the patient has achieved treatment response following intensive chemotherapy. Given the aggressive nature and treatment intensity (similar to acute leukemia protocols), remission documentation is particularly important for ongoing surveillance and risk adjustment. Relapse surveillance typically continues for several years.
Documentation Requirements
- ✓Explicit provider documentation of complete remission
- ✓End-of-treatment imaging showing no evidence of disease
- ✓Bone marrow biopsy confirming no residual disease
- ✓Date remission was achieved
- ✓Surveillance plan and schedule for relapse monitoring
