Traum rupture of unsp ligmt of l rng fngr at MCP/IP jt, init

This code signifies a tear or complete disruption of an unidentifiable ligament within the left ring finger, affecting both the knuckle (metacarpophalangeal) and finger (interphalangeal) joints. This injury is a direct result of trauma, such as a hyperextension or twisting force.

Apply this code for initial encounters with patients presenting with an acute, traumatic rupture of a ligament in the left ring finger where the specific ligament involved cannot be definitively identified. This is appropriate when the injury affects both the MCP and IP joints of that digit.

• Ensure documentation specifies "left ring finger" and "unspecified ligament" for accurate code assignment.
• Verify the encounter is "initial" for this specific injury; subsequent care will require a different seventh character.
• Confirm the injury involves both the metacarpophalangeal and interphalangeal joints of the ring finger.
