Sprain of interphalangeal joint of left index finger, subs

This code signifies a sprain of the joint located between the phalanges of the left index finger. It indicates that the patient is receiving follow-up care for an injury to the ligaments supporting this specific joint, beyond the initial treatment phase.

Apply this code when documenting subsequent visits for a patient recovering from a left index finger interphalangeal joint sprain. This includes physical therapy, re-evaluation of healing, or management of ongoing symptoms after the initial injury has been addressed. Do not use for the initial injury encounter.

• Ensure documentation specifies the left index finger and the interphalangeal joint.
• Verify the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Confirm the diagnosis is a sprain, not a fracture or dislocation.
