When documenting sequelae, what must be indicated in the coding?

When documenting sequelae, it is essential to indicate a condition that results from a previous diagnosis. Sequelae refer to the aftereffects of a disease or injury, which can manifest long after the initial condition has resolved. Proper coding requires clarity on this aspect, as it allows healthcare providers, insurers, and researchers to understand the ongoing impact of a prior condition on the patient's health. This ensures that patients receive appropriate follow-up care and that any necessary treatments are linked to the history of the disease.

In contrast, the other options do not relate to the concept of sequelae. A new and unrelated diagnosis would represent a separate health issue, a preventive treatment method pertains to measures taken to avoid illness rather than documenting existing conditions, and a transitory illness refers to a temporary condition rather than a lasting effect from a prior diagnosis. Therefore, indicating a condition resulting from a previous diagnosis is essential in coding sequelae effectively.
