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

This code describes a traumatic tear of a ligament in the left ring finger, specifically at either the metacarpophalangeal (MCP) or interphalangeal (IP) joint, that is being treated during a subsequent encounter. This injury is not a sprain, but a complete or partial rupture of a ligament other than the collateral ligaments.

Use this code for follow-up visits, cast changes, physical therapy sessions, or medication management for a patient previously diagnosed with a traumatic rupture of a non-collateral ligament in the left ring finger's MCP or IP joint. This code is appropriate once the initial active treatment phase has concluded and the patient is in the healing or recovery phase.

• Ensure the documentation clearly specifies a rupture and not just a sprain, and identifies the specific ligament if known, or "other ligament" if not.
• Verify the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Confirm the injury is to the left ring finger and at either the MCP or IP joint.
