Sublux of unsp interphaln joint of l little finger, sequela

This code signifies a partial dislocation or misalignment of an interphalangeal joint in the left little finger that is no longer an acute injury but rather a long-term consequence. It indicates that the joint surfaces are still in partial contact, but their normal anatomical relationship is disrupted, leading to potential ongoing symptoms or functional limitations.

Apply this code when documenting a patient presenting with a history of a finger injury to the left little finger, where imaging or physical examination confirms a persistent subluxation of an interphalangeal joint. This is appropriate for follow-up visits addressing chronic pain, stiffness, or functional impairment directly attributable to the past subluxation. It should be used when the initial acute injury has resolved, but the subluxation remains as a sequela.

• Ensure documentation clearly states the left little finger and specifies "sequela" to justify this seventh character.
• Do not use this code for acute subluxations; those require different seventh characters (e.g., A, D).
• Pair this code with an external cause code if the original injury mechanism is known and relevant for the encounter.
