Sprain of interphalangeal joint of left index finger, init

This code signifies a ligamentous injury (sprain) affecting the joint between the phalanges of the left index finger. It specifically refers to the initial presentation or active treatment phase of such an injury. The sprain indicates stretching or tearing of the ligaments supporting this particular finger joint.

Use this code for patients presenting with a newly diagnosed sprain of the interphalangeal joint of their left index finger, or when they are actively receiving treatment for this injury. This would include scenarios like an acute injury from a fall, sports activity, or direct trauma to the finger. It is appropriate for the initial evaluation and subsequent visits during the acute phase of care.

• Ensure documentation specifies "left" index finger and "interphalangeal" joint.
• Confirm the encounter is "initial" for this specific injury, not a subsequent encounter for healing or sequela.
• Distinguish from fractures, dislocations, or sprains of other finger joints.
