Sprain of MCP joint of right little finger, subs

This code signifies a sprain affecting the joint between the metacarpal bone and the first phalanx of the right little finger. It indicates damage to the ligaments supporting this specific joint, without a fracture or dislocation.

This code is appropriate for follow-up visits, such as during physical therapy, re-evaluation, or medication management, after initial treatment for a right little finger metacarpophalangeal joint sprain. It should be used when the patient is still receiving active treatment for the injury.

• Ensure the encounter is for subsequent care, not the initial injury.
• Verify the sprain is specifically of the metacarpophalangeal joint and not another joint of the finger.
• Confirm the laterality is correctly documented as the right little finger.
