Sprain of interphalangeal joint of right great toe, subs

This code signifies a sprain affecting the joint between the bones of the right great toe, specifically when the patient is receiving follow-up care for this injury. It indicates that the initial treatment has already occurred, and the current encounter is for continued management, healing, or rehabilitation.

Apply this code for office visits, physical therapy sessions, or other encounters where a patient is being seen for ongoing care of a previously diagnosed sprain of the right great toe's interphalangeal joint. This includes monitoring recovery, assessing progress, or managing complications after the acute phase.

• Ensure the encounter is for follow-up care, not the initial injury or a new injury.
• Verify laterality (right great toe) and the specific joint (interphalangeal).
• Always pair with an external cause code if the injury mechanism is known and relevant to the encounter.
