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

This code signifies a traumatic tear of an unidentifiable ligament within the left ring finger, affecting both the knuckle (metacarpophalangeal) and finger (interphalangeal) joints. This diagnosis is specifically for a patient receiving follow-up care for this injury, such as during rehabilitation or post-operative visits.

Apply this code when documenting subsequent encounters for a patient who has previously been diagnosed with a traumatic rupture of an unspecified ligament in their left ring finger, involving both the MCP and IP joints. This includes visits for physical therapy, wound care, cast changes, or follow-up evaluations after initial treatment.

• Ensure the encounter is for follow-up care, not the initial injury.
• Confirm the injury location is the left ring finger and involves both MCP and IP joints.
• "Unspecified ligament" should be used when the specific ligament (e.g., collateral, volar plate) is not documented.
