Contusion of unspecified ankle, subsequent encounter

This code signifies a bruise to an unspecified ankle that is being treated or evaluated after the initial encounter. It indicates soft tissue damage, such as bleeding under the skin, without a fracture or open wound, affecting the ankle joint area.

This code is appropriate for follow-up visits, such as re-evaluations, physical therapy sessions, or medication adjustments, for a previously diagnosed ankle contusion where the specific ankle (left or right) was not documented. It should be used when the patient is receiving active treatment for the injury.

• Ensure documentation clearly states "subsequent encounter" or indicates ongoing treatment for the contusion.
• Avoid using this code if the laterality (left or right ankle) is specified in the medical record; instead, use the more specific S90.01XD or S90.02XD.
• Do not use for initial encounters; refer to S90.00XA for the initial treatment of an unspecified ankle contusion.
