0.000What This Code Means
Hodgkin lymphoma of unspecified type that is currently in remission, meaning the cancer is not actively growing or has responded to treatment.
Coding Tips
- •Only use this code when documentation explicitly states the patient is in remission or complete response
- •Do not use if there is any evidence of active disease
Clinical Significance
Hodgkin lymphoma of unspecified type in remission indicates a treatment response in a patient whose original histologic subtype was not classified. Despite the lack of subtype specificity, the remission status is clinically meaningful as it drives ongoing surveillance requirements. This code maintains HCC mapping during the post-treatment monitoring period and should be used until the patient is discharged from active oncologic surveillance.
Documentation Requirements
- ✓Explicit provider documentation of remission status
- ✓Supporting imaging demonstrating no active disease
- ✓History of confirmed Hodgkin lymphoma diagnosis
- ✓Surveillance plan with follow-up schedule
- ✓Encounter documentation confirming ongoing remission
Commonly Confused Codes
C81.90-C81.99 — Active unspecified Hodgkin lymphoma codes: use these when disease is still active; transition to C81.9A for documented remissionZ85.71 — Personal history of Hodgkin lymphoma: use only when the patient is considered cured and discharged from oncologic surveillance; C81.9A is for active monitoring in remissionC81.7A — Other Hodgkin lymphoma, in remission: use when the subtype was classified as 'other' rather than truly unspecified
