Dislocation of interphalangeal joint of left thumb, sequela

This code signifies a past dislocation of the interphalangeal (IP) joint of the left thumb, where the patient is still experiencing residual effects or complications from that prior injury. It indicates that the initial acute phase of the dislocation has passed, but the patient's current condition is a direct consequence of that previous trauma.

Use this code when documenting follow-up care for a patient who previously sustained an IP joint dislocation of the left thumb and is now presenting with chronic pain, instability, stiffness, or other long-term sequelae related to that injury. It is appropriate for conditions like post-traumatic arthritis, chronic ligamentous laxity, or persistent range of motion limitations stemming from the original dislocation.

• Always code the specific sequela first, followed by this sequela code.
• Ensure documentation clearly links the current condition to the prior left thumb IP joint dislocation.
• Do not use for acute dislocations; those require codes from the acute injury section.
