Sprain of interphalangeal joint of left lesser toe(s), init

This code signifies a sprain affecting one or more of the interphalangeal joints (PIP or DIP) of any of the lesser toes (toes 2-5) on the left foot. It indicates that the ligaments supporting these joints have been stretched or torn, but not completely ruptured or dislocated.

Apply this code when documenting the initial treatment for a patient presenting with pain, swelling, and tenderness localized to an interphalangeal joint of a left lesser toe following a twisting injury or hyperextension. This is appropriate for the first encounter for this specific injury, regardless of whether definitive treatment is provided or further evaluation is planned.

• Ensure documentation specifies the left foot and identifies the affected joint as interphalangeal, not metatarsophalangeal.
• Confirm this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from fractures or dislocations, which would be coded differently.
