Laceration of posterior tibial artery, unsp leg, subs encntr

This diagnosis code signifies a tear or cut in the posterior tibial artery, located in the lower leg, when the specific leg (left or right) is not documented. It indicates that the patient is receiving follow-up care for this injury after the initial treatment.

Apply this code when a patient presents for ongoing management, such as wound care, monitoring for complications, or rehabilitation, following an acute laceration of the posterior tibial artery where the affected leg is not specified. This would be used after the initial encounter for the injury has been coded.

• Ensure documentation clearly states "subsequent encounter" for this specific injury.
• If the laterality (left or right leg) is documented, a more specific code should be chosen.
• Always sequence this code after any codes for the primary reason for the subsequent encounter (e.g., wound infection, pain management).
