Sprain of metacarpophalangeal joint of left ring finger, initial encounter

📋Clinical Description

This diagnosis code signifies a ligamentous injury (sprain) affecting the joint between the metacarpal bone and the first phalanx of the left ring finger. It indicates damage to the connective tissues stabilizing this specific knuckle joint.

🎯When to Use

Use this code for a patient presenting with an acute injury to the left ring finger's metacarpophalangeal joint, such as from a fall, direct impact, or hyperextension. This code is appropriate for the initial visit where the injury is first evaluated and treated.

💡Coding Tips

Ensure documentation clearly specifies the left ring finger and the metacarpophalangeal joint.
Verify the encounter is indeed the "initial encounter" for this specific injury.
Distinguish from dislocations (S63.2-) or fractures (S62.6-) of the same joint.
