Sprain of interphalangeal joint of left ring finger, init

This code signifies a ligamentous injury to the joint between the phalanges of the left ring finger. It indicates a stretching or tearing of the connective tissues supporting this specific joint, without a fracture or dislocation. The "initial encounter" designation means the patient is receiving active treatment for this acute injury.

Apply this code when a patient presents with a sprain of the interphalangeal joint of their left ring finger, such as from a sports injury, fall, or direct impact. This code is appropriate for the initial visit where the injury is diagnosed and treatment begins. Subsequent encounters for follow-up care or healing would require a different seventh character.

• Ensure the documentation clearly specifies the left ring finger and the interphalangeal joint.
• Verify that the injury is indeed a sprain and not a fracture or dislocation, which would require different codes.
• Confirm "initial encounter" is appropriate for the patient's current stage of treatment.
