Sprain of interphalangeal joint of right little finger, init

This code signifies a ligamentous injury to the joint between the phalanges of the right little finger. This type of sprain involves stretching or tearing of the connective tissues stabilizing the interphalangeal joint, without a fracture or dislocation. Patients typically present with pain, swelling, and limited range of motion in the affected digit.

Apply this code when documenting an acute sprain of either the proximal or distal interphalangeal joint of the right little finger. This is appropriate for initial evaluations following a traumatic event, such as a hyperextension injury or direct impact. It should be used when the patient is receiving active treatment for the injury.

• Ensure documentation specifies the right little finger and an interphalangeal joint sprain.
• Verify this is the patient's first encounter for this specific injury, indicating active treatment.
• Distinguish from fractures (S62.-) or dislocations (S63.0-S63.1) of the same joint.
