Sprain of interphalangeal joint of right index finger, init

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

This code is appropriate for documenting an acute sprain of the interphalangeal joint of the right index finger, such as from a "jammed finger" injury during sports or a fall. It should be used for the initial encounter when the patient is receiving active treatment for the injury. Subsequent encounters for follow-up care or healing would require a different seventh character.

• Ensure documentation specifies the right index finger and the interphalangeal joint.
• Verify that the encounter is indeed the initial treatment for this specific injury.
• Distinguish sprains from fractures or dislocations, which have different codes.
