Sprain of MCP joint of right little finger, init

This code signifies a ligamentous injury, or sprain, affecting the joint between the metacarpal bone and the first phalanx of the right little finger. This type of injury typically involves stretching or tearing of the joint capsules and collateral ligaments, resulting in pain, swelling, and limited range of motion.

Apply this code when documentation confirms a sprain of the right little finger's metacarpophalangeal (MCP) joint, such as from a hyperextension injury or direct trauma. This code is specifically for the initial treatment or evaluation of the injury.

• Ensure laterality (right) and specific joint (MCP of little finger) are clearly documented.
• Verify that the encounter is indeed the "initial encounter" for this specific injury.
• Distinguish sprains from fractures, dislocations, or other soft tissue injuries.
