Follow-up

The follow-up codes are used to explain continuing surveillance following completed treatment of a disease, condition, or injury. They imply that the condition has been fully treated and no longer exists. They should not be confused with aftercare codes, or injury codes with a 7th character for subsequent encounter, that explain ongoing care of a healing condition or its sequelae.

Follow-up codes may be used in conjunction with history codes to provide the full picture of the healed condition and its treatment. The follow-up code is sequenced first, followed by the history code. A follow-up code may be used to explain multiple visits.

Should a condition be found to have recurred on the follow-up visit, then the diagnosis code for the condition should be assigned in place of the follow-up code.

The follow-up Z codes/categories: Z08 Encounter for follow-up examination after completed treatment for malignant neoplasm Z09 Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm Codes Z08, Encounter for follow-up examination after completed treatment for malignant neoplasm, and Z09, Encounter for follow up examination after completed treatment for conditions other than malignant neoplasm, may be assigned following any type of completed treatment modality (including both medical and surgical treatments).
