Sprain of MCP joint of right middle finger, init

This diagnosis code indicates a sprain, or ligamentous injury, affecting the joint between the metacarpal bone and the first phalanx of the right middle finger. This injury involves stretching or tearing of the ligaments supporting this specific joint, often resulting in pain, swelling, and limited range of motion.

Apply this code when documenting the initial treatment for a patient presenting with a sprain of the right middle finger's metacarpophalangeal joint. This typically occurs following a hyperextension injury, direct impact, or twisting force to the finger. It is appropriate for the first visit related to this specific injury.

• Ensure laterality (right) and specific digit (middle finger) are accurately documented.
• Confirm the encounter is indeed the "initial encounter" for this injury; subsequent care would use a different seventh character.
• Distinguish from fractures or dislocations, which would require different codes.
