In cases where a primary malignancy has been previously treated, how should the encounter be coded if there's no current malignancy evidence?

In cases where a primary malignancy has been previously treated, using a Z85 code is correct because Z85 codes are specifically designated to indicate a personal history of malignant neoplasm. This coding signifies that while there is no current evidence of malignancy, the individual has a history that may be pertinent to their health status and future medical decisions.

The Z85 code serves an important purpose in patient records by informing healthcare providers that the patient has dealt with cancer in the past, which could impact ongoing care, monitoring, and treatment for other conditions. It allows for proper documentation and continuity of care, highlighting the necessity to be vigilant for any potential recurrence or related health issues.

In contrast, coding for malignancy detection would imply that there is an active assessment for current cancer, which is not the case here. A secondary neoplasm code would suggest that there is an active, currently diagnosed secondary cancer, which is also not applicable in the absence of current malignancy evidence. Finally, stating that no code is needed would disregard the importance of documenting a history of malignancy, which is required for comprehensive patient care.
