Sprain of MTP joint of left lesser toe(s), subs

This code signifies a sprain affecting the joint where a metatarsal bone meets a phalanx bone in one of the left foot's lesser toes (not the big toe). A sprain indicates damage to the ligaments supporting this joint, ranging from stretching to tearing.

Apply this code when a patient is receiving follow-up care for a previously diagnosed sprain of the metatarsophalangeal joint of a left lesser toe. This includes rehabilitation, cast changes, or ongoing evaluation of healing. It should not be used for the initial injury or for sequelae.

• Ensure documentation specifies "left" and "lesser toe(s)" to differentiate from the great toe or right foot.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Confirm the injury is a sprain, not a fracture or dislocation, and that it affects the MTP joint specifically.
