  • Subsequent Encounters in ICD-10

    ICD-10 has a number of codes which refer to ‘Subsequent Encounters’… just what does this term mean?

    For example,

    W59.22XD – Struck by turtle, subsequent encounter

    V93.41XD – Struck by falling object on passenger ship, subsequent encounter

    T75.01XD – Shock due to being struck by lightning,  subsequent encounter


    Carl Natale has an excellent post explaining just what a ‘Subsequent Encounter’ is.  Contrary to popular belief these codes do not mean the 2nd time something happened. After all, what is the probability of being struck by a turtle, an object on a passenger ship or lightning a 2nd time!

    Instead a subsequent encounter simply means that a patient is receiving routine care during the healing process for the injury.

    For most ICD-10 diagnosis codes, the 7th character indicates the following,

    • A – Initial encounter. The patient is receiving active treatment for the injury
    • D – Subsequent encounter. Used for encounters after the patient has received active treatment of the injury and is receiving routine care for the injury during the healing or recovery phase
    • S – Sequela. Used to indicate complications or conditions that arise as a direct result of an injury
